Best Budget Door Lock for Woodworkers: Kata Kit Wins

The best budget door lock for woodworkers is the Kata KT20531 installation kit, because it adjusts across 1-3/8" to 1-3/4" doors and ships with the 1" and 2-1/8" hole saws you'd otherwise buy separately. The Milescraft 1338 Lock Mate PLUS is the pick if your shop has metal-skinned doors, since its bi-metal cobalt hole saws cut both wood and metal. I compared the published specifications for seven listings side by side and picked the deciding differences by hand.

A quick note on the search itself. "Woodworkers" as a qualifier is only partly reflected in what Amazon returned: some picks are installation jigs a woodworker will actually use, others are finished locks or lockout devices that any homeowner might buy. I've flagged which is which so you aren't guessing.

Best budget door lock for woodworkers at a glance

How I sorted seven listings into a working shortlist

The keyword covers two very different jobs. One is fitting a lock into a fresh door, which is where the drilling jigs earn their keep. The other is adding or restricting a lock on a door that's already hung. I judged each pick by the criteria that matter for its own job, so I'm not scoring an installation kit against a portable travel lock on the same scale.

Three criteria did most of the sorting.

1. Fit range. The jig picks had to publish a door-thickness range that covers standard residential stock. Both jigs here list 1-3/8" and 1-3/4", which is what a woodworker sees on nearly every interior door.
2. What's included. A budget kit that ships hole saws and an arbor saves you a second trip. The Kata KT20531 and the Milescraft 1338 both list the same 1" and 2-1/8" hole saws.
3. Honest scope. The Kata listing says outright it's for wood doors and not for metal, security or fiberglass. That's the right sort of disclosure for a budget kit, and it's why the Milescraft is the pick if you also need to cut steel.

Two picks in this set aren't locks for installation at all. The PRIME-LINE S 4180 and the PUGED handle cover restrict access to an existing lock. The AceMining is a portable brace. I've kept them in because a shop or a home workshop often needs one of these to solve a specific problem faster than swapping hardware.

What actually decides a shop door lock buy

Most guides for the best budget door lock for woodworkers compare finishes and key counts. Those don't decide the purchase. The deciding criterion is the match between three numbers: your door thickness, the backset for the latch, and the bore diameter your new lock needs. Get any one of those wrong and the lock doesn't sit flush, the latch doesn't reach, or the knob spins.

The two installation jigs in this roundup both target the two most common thicknesses in North American interior doors: 1-3/8" and 1-3/4". The Alarm Lock DL2700 lists a slightly different range, 1-5/8" to 1-7/8", which is worth noting if you're upgrading a heavier shop door. The bore diameters the jigs cut are standard for cylindrical locksets: 2-1/8" for the face bore and 1" for the edge bore.

Here's the trick with budget kits. The plastic template in a low-cost jig is the part that fails first, so a metal-lined bushing (as the Milescraft lists) matters more than the finish on the hole saws. If a template goes soft, the hole drifts and the lock face won't sit square. That single detail is why the two jigs land where they do in this ranking.

1. Kata KT20531 Installation Kit — Best overall

The Kata kit is the pick for a woodworker who needs a working door lock jig without paying for pro-grade tooling.

Best for: a woodworker fitting or replacing knob locks on 1-3/8" to 1-3/4" wood doors Skip it if: your shop door is steel-clad or fiberglass

This is the cheapest of the seven picks, and it's built to do one job cleanly. The kit includes a U-type adjustable reinforced plastic guide template, a 1" hole saw, a 2-1/8" hole saw, and an arbor with a drill bit for the latch bore. That's four pieces (specs list a count of 4) covering the two cuts every cylindrical lockset needs. Total weight is 0.73 lb, and the packed dimensions of 3.3 x 7 x 6.4 in mean it stores flat on a shelf beside your other jigs.

Kata is direct in the listing about what it isn't for: not metal doors, not security doors, not fiberglass, not commercial use. That's exactly the honesty a budget tool needs. The trade-off against the Milescraft is the template material. Kata's is reinforced plastic; Milescraft uses metal-lined stepped drill guide bushings. If you're fitting one or two locks a year on wood interior doors, plastic is fine. If you fit ten a year across mixed materials, it isn't.

Pros:

• Cheapest kit in this set
• Covers 1-3/8" to 1-3/4" doors in one jig
• Ships 1" and 2-1/8" hole saws included
• Arbor and drill bit for the latch bore in the same box
• Limited warranty listed

Cons:

• Plastic guide template, not metal-lined
• Wood doors only, not metal or fiberglass
• No self-clamping mechanism
• Only one seller lists it

2. Milescraft 1338 Lock Mate PLUS — Runner-up

The Milescraft is the pick if your shop door might be steel-skinned or hollow-core metal.

Best for: someone who wants a jig that self-clamps and cuts metal doors too Skip it if: you only ever drill one or two locks a year

Milescraft says this jig self-clamps to the door with no screws or hardware, and no surface damage. That matters on a finished door where a screwed-on template would leave witness marks. The listing also says the metal-lined stepped drill guide bushings prevent damage and extend the life of the jig, which is the single durability advantage over the Kata. The hole saws are bi-metal cobalt alloy in 1" and 2-1/8" sizes, and the listing states they cut both wood and metal, solid or hollow core.

The jig adjusts for the same 1-3/8" and 1-3/4" standard thicknesses as the Kata. Milescraft sits in the premium price band of this set, and it's the second-most expensive here. Against the Kata, you're paying for two things: the self-clamping action and the bi-metal saws. If your shop has a steel-clad entry door, that's money well spent. If it's all interior wood, the Kata does the same core job.

Pros:

• Self-clamps without screws or surface damage
• Bi-metal cobalt hole saws cut wood and metal
• Metal-lined stepped drill guide bushings
• Adjusts for 1-3/8" and 1-3/4" doors
• Solid or hollow-core capable

Cons:

• Priced in the premium band of this set
• Fewer published dimensions than the Kata
• No warranty listed
• Only one seller lists it

3. AceMining Portable Door Lock — Best for beginners

A no-drill brace for anyone who wants a lock without touching the door.

Best for: renters or travellers who need a lock they can add without drilling Skip it if: you need a permanent lock for a shop entry door

At 4.16 oz and 0.8 x 5.12 x 1.65 in, this is the smallest and lightest pick in the set. AceMining says it installs in seconds without tools, even in the dark, and the ABS cover is there to keep the metal from marking the door. The listing describes strong stainless steel construction and two holes of different sizes to match different lock types. It's the one buyers choose most often here, if the category sales data is anything to go by.

For a woodworker, this isn't a shop-door solution. It's a travel or rental solution, and it fills a gap none of the other picks addresses. If you rent a workshop space and can't modify the door, this adds a physical barrier without a jig, without a drill, without ever pulling out a screwdriver. The trade-off is obvious: it only works from the inside, and it comes off with the door. Against the two jigs, it isn't installing anything at all.

Pros:

• No tools needed
• 4.16 oz packable weight
• Stainless steel with ABS cover
• Works with two lock hole sizes
• Cheapest non-installation pick here

Cons:

• Only works from the inside
• Not a permanent solution
• No warranty listed
• Doesn't help a woodworker fit a new lock

4. PRIME-LINE S 4180 Door Knob Lock-Out — Best large-capacity

Covers the keyhole on a keyed doorknob without replacing the knob.

Best for: a landlord or shop owner blocking keyholders from a doorknob they don't want to swap Skip it if: your knob is larger than 2-7/16 in. in diameter

The PRIME-LINE is a diecast metal shell that fits round doorknobs up to 2-7/16 in. in diameter with a 1-3/16 in. circular shaft opening. It weighs 1.34 lb, sits at 2.75 x 3.75 x 2.25 in, and comes with a removable cylinder secured by an O-ring for cleaning when unlocked. PRIME-LINE lists a one-year warranty against manufacturing defects, which is one of only two published warranties in this set.

The use case is narrower than the jigs but specific: rentals, home sales, evictions, job sites, offices, storage rooms. If a woodworker runs a rental workshop or a shared shop, this blocks other keyholders from getting in without swapping the entire knob assembly. Measure the outside diameter of your doorknob before ordering; it's the one number that decides fit. Against the PUGED cover below, this one is for round knobs, not lever handles.

Pros:

• Fits knobs to 2-7/16 in. diameter
• Diecast metal construction
• Removable cylinder for cleaning
• One-year warranty listed
• Two sellers stock it

Cons:

• Round knobs only, not levers
• Doesn't fit knobs over 2-7/16 in.
• No included key measurement guidance beyond the listing
• Not a solution for fitting a new lock

5. PUGED Keyed Handle Lockout — Best for families

A code-lock cover that blocks a lever-handle door without replacing it.

Best for: households locking out a lever-handle bedroom or office door with a code Skip it if: your handle shaft falls outside 1.1 to 1.26 in.

The PUGED cover works only on handle locks where the connecting shaft between the handle and the lock body measures 1.1 to 1.26 in. That number is the whole story: measure it before you order or the cover won't fit. PUGED says the shell is made of high-quality metal with powder coating for long-time use, and the code design means no key to lose. It weighs 0.7 lb and measures 2.17 x 3.76 x 2.75 in.

For a family shop where a lever-handle office door needs to be locked to kids without replacing the handle, this solves the problem faster than a new lockset. The trade-off against the PRIME-LINE is form factor: this one is for lever handles, the PRIME-LINE is for round knobs, and neither fits both. It's mid-priced in this set, sitting above the two entry-band lockout picks but well below the premium ones.

Pros:

• Combination code, no key needed
• Powder-coated metal shell
• Removable and portable
• Works from the outside on lever handles
• Specific fit range published

Cons:

• Only fits shafts 1.1" to 1.26"
• Lever handles only
• No warranty listed
• The slowest seller of the three lockout picks

6. MCAVORY Storefront Mortise Cylinder — Best for heavy use

Replacement cylinder for aluminum-frame storefront doors.

Best for: aluminum storefront or narrow-frame glass doors on a workshop Skip it if: you have a standard residential wood door

If your shop entry is a glass storefront door in an aluminum frame, this is the only pick that fits it. The MCAVORY set is a standard 1-inch length, 1-5/32" diameter mortise cylinder that fits Adams Rite, Kawneer, Vistawall, and most other storefront door locksets. The kit includes a keyed lock cylinder, two keys, a thumbturn, and two cylinder collars. Keys are SC1 with a 5-pin C keyway and Adams Rite cam.

This is a component, not a lock kit. You need an existing storefront deadbolt, hook lock, or deadlatch to install it into. For a woodworker who runs a small commercial shop with a glass front door, the MCAVORY is often the cheapest way to rekey. Against the residential picks in this list, it targets a completely different door type. Best for heavy use as an award reflects the commercial-glass context, not extra durability testing.

Pros:

• Fits Adams Rite, Kawneer, Vistawall frames
• Includes two keys, thumbturn, two collars
• SC1 5-pin C keyway
• Standard 1-inch mortise length
• Commercial application coverage

Cons:

• Only fits narrow aluminum-frame storefront doors
• No warranty listed
• Not usable on wood or metal residential doors
• Only one seller lists it

7. Alarm Lock DL2700 Trilogy — Best premium

Electronic keyless lever lock with 100 user codes.

Best for: a busy shop that needs keyless entry with up to 100 user codes Skip it if: you want a simple mechanical fix

This is the most expensive pick here, and it's the odd one out on a budget list. Alarm Lock says the DL2700 is programmable through the keypad for 100 user entry codes, with a fixed 6-pin key cylinder on the SC1 keyway as a key override. The lever is reversible for right- or left-hand operation. It's built for interior doors 1-5/8" to 1-7/8" thick, weighs 8 lb, and measures 11.9 x 9 x 11.8 in in the box. The trim is stainless steel with a satin chrome finish.

For a woodworker running a shared shop, keyless entry with per-user codes solves the "who has a key" problem outright. Alarm Lock mentions real-time automated lock/unlock schedules in the listing. This isn't a budget pick in the strict sense, but it's the option to know about when a mechanical solution won't scale. The trade-off is obvious: it costs several times what the Kata kit does, and it doesn't help you fit a lock into a new door.

Pros:

• 100 user codes programmable via keypad
• 6-pin SC1 key override
• Reversible lever
• Stainless steel with satin chrome trim
• Real-time schedules listed

Cons:

• Most expensive pick in this set
• Fits only 1-5/8" to 1-7/8" doors
• No warranty listed
• The slowest seller of the seven

Installation kit or finished lock: which do you need?

This is the fork in the road for anyone searching the best budget door lock for woodworkers. An installation kit is a jig plus hole saws. A finished lock is the hardware you fit with the kit. You need both to complete a door, and this roundup mostly covers the kit side, plus three retrofits that skip installation altogether.

• Choose a kit if you're fitting a new lock into a fresh door slab or replacing an existing lockset in wood or metal. The Kata KT20531 for wood-only, the Milescraft 1338 for mixed.
• Choose a retrofit cover if you have a working lock but need to block a specific keyholder. PRIME-LINE for round knobs, PUGED for lever handles.
• Choose a portable brace if you can't modify the door. AceMining.
• Choose a component if you're rekeying an existing storefront cylinder. MCAVORY.
• Choose an electronic lock if you want per-user codes on a shared shop door. Alarm Lock DL2700.

For most woodworkers doing shop or home projects, the kit is the answer. The rest are edge cases with sharp use profiles.

What to check before you drill the first hole

Before you clamp a jig on a finished door, work through this list. Ninety percent of failed lock installs trace back to a missed measurement or a mismatched bore.

1. Door thickness. Measure at the latch edge, not through a rebate. Standard residential is 1-3/8" or 1-3/4". Confirm your jig covers your number.
2. Backset. This is the distance from the door edge to the centre of the face bore, usually 2-3/8" or 2-3/4". Your lockset lists the backset it needs; the jig has to match.
3. Face bore diameter. Cylindrical locksets almost always take a 2-1/8" bore. Both jigs here include the 2-1/8" hole saw.
4. Edge bore diameter. Standard is 1", which both jigs also cover.
5. Door material. Wood-only for the Kata. Wood or metal, solid or hollow core, for the Milescraft.
6. Strike plate location. Mark and mortise the jamb before hanging the lock; a jig doesn't cover the frame side.

Skip this list at your peril: the hole saw won't back out cleanly once you're wrong.

Which pick fits your door thickness?

Door thickness is the single most-quoted number in this roundup, and it splits the picks into three clear bands. Here's how they fall.

• 1-3/8" to 1-3/4": Kata KT20531, Milescraft 1338. Standard residential range, covers most interior doors in North American homes.
• 1-5/8" to 1-7/8": Alarm Lock DL2700. Heavier interior stock, more typical of commercial or heavy shop doors.
• Not thickness-dependent: AceMining (portable brace), PRIME-LINE S 4180 (fits knob diameter), PUGED (fits handle shaft length), MCAVORY (fits aluminum storefront frame).

If your door thickness falls outside 1-3/8" to 1-7/8", none of the installation picks here will match without modification. That's a real limit of the budget category. A woodworker fitting locks on a 2-1/4" solid slab, for instance, needs a jig with a wider fit range than any of these list.

The verdict

The winner is the Kata KT20531 installation kit. It's the cheapest of the seven picks, it covers the two door thicknesses most woodworkers actually meet, and it ships every part you need to cut both the face and edge bores in one box. That combination is what the best budget door lock for woodworkers should mean, and no other pick here matches it at this price position.

Two conditions flip the pick. First, if your shop has steel-skinned or hollow-core metal doors, the Milescraft 1338 Lock Mate PLUS is the right answer. It self-clamps without marking the door, its metal-lined bushings outlast a plastic template, and its bi-metal cobalt hole saws cut metal cleanly. Second, if you're not installing a lock at all and you need to restrict access to one that's already fitted, one of the three retrofits solves the problem without a jig: PRIME-LINE for round knobs, PUGED for lever handles, or AceMining for a no-drill brace.

The Alarm Lock DL2700 is the specialist pick for a shared shop that needs per-user codes, but it isn't a budget lock in any honest reading. Start with the Kata.

FAQ

Is a budget door lock installation kit worth it for a woodworker?

A budget installation kit is worth it for a woodworker fitting one to five locks a year on residential doors. The Kata KT20531 includes the 1" and 2-1/8" hole saws and an arbor with drill bit, so you're not buying accessories separately. The plastic template is the durability limit; if you fit ten or more locks a year, step up to the metal-lined bushings on the Milescraft 1338.

What door thickness do these budget kits actually fit?

The door thickness range on both jig picks is 1-3/8" to 1-3/4", which covers standard North American interior doors. The Alarm Lock DL2700 lever lock fits 1-5/8" to 1-7/8" doors instead, so it targets heavier stock. If your slab falls outside 1-3/8" to 1-7/8", none of the installation picks in this roundup will match without extra work on the jig.

Kata KT20531 or Milescraft 1338 Lock Mate PLUS: which should I buy?

Choose between the Kata KT20531 and the Milescraft 1338 by door material. Kata is cheaper and cuts wood doors only, per its listing. Milescraft costs more, self-clamps without screws, and its bi-metal cobalt hole saws cut both wood and metal, solid or hollow core. For a home shop with wood interior doors, buy Kata. For a shop with steel-clad or hollow metal doors, pay up for Milescraft.

Can I use a portable door lock instead of drilling one in?

You can use a portable door lock like the AceMining as a brace, but it's not a substitute for a fitted lock. It weighs 4.16 oz, installs in seconds without tools, and works from the inside only. That means it protects a room while you're in it, not while you're away. For a shop entry door you leave unattended, drill in a proper lockset with the Kata or Milescraft jig.

What's the biggest mistake when buying a budget lock kit?

The biggest mistake when buying a budget lock kit is ignoring backset. Most cylindrical locksets need either a 2-3/8" or 2-3/4" backset, and your jig has to line up the face bore to match the lockset you're installing. The second mistake is buying a wood-only kit like the Kata for a metal door. Read the listing's material notes before you clamp anything on.

The best next step is to measure your door thickness at the latch edge, note the backset your existing lockset uses, and confirm those two numbers before you click buy. For the majority of woodworkers, that check ends with the Kata KT20531 in the cart: it's the cheapest working kit in this set, its 1" and 2-1/8" hole saws match the standard cylindrical lockset bores, and the 1-3/8" to 1-3/4" fit range covers the doors you're most likely to be working on. Keep the Milescraft in mind if a metal door shows up on the job.
