Drill Chuck Sets for Trade, DIY and Workshop Use
A worn or slipping drill chuck ruins your work and wastes time. Whether you need to replace a Milwaukee drill chuck or replace a DeWalt drill chuck, we have the right part. This range covers keyed drill chucks, keyless drill chucks, hex adapter drill chucks, and SDS adapters. All suitable for corded and cordless drills used across the UK. Find the correct chuck size and thread type before you order.
What Is a Drill Chuck and Why Does It Matter?
A drill chuck holds the drill bit in place during use. It grips the shank of the bit firmly so it does not slip. A faulty chuck causes bit wobble, inaccurate holes, and safety risks.
Over time, chucks wear out. The jaws lose grip. The threads can strip or seize. This is normal after heavy use. Replacing the chuck is far cheaper than buying a new drill.
This range covers replacement drill chucks for popular brands. It also includes chuck adapters, hex shank adapters, and SDS-plus adapters. Suitable for most standard drills used on UK sites and in home workshops.
Quick tip: Check your drill's spindle thread before ordering a replacement chuck. Common UK threads are 1/2 inch UNF and 3/8 inch UNF. Using the wrong thread will prevent the chuck from fitting correctly.
Types of Drill Chucks in This Range
Not all drill chucks are the same. Here is a breakdown of each type and what it is best for.
Keyless Drill Chuck
A keyless chuck tightens and loosens by hand. No chuck key is needed. You can swap bits quickly between tasks. Popular on cordless drills and driver-drills. Good for general drilling and screw driving in trade and DIY.
Keyed Drill Chuck
A keyed chuck uses a small T-handle key to tighten the jaws. It gives a stronger and more secure grip than keyless types. Preferred for heavy-duty drilling in metal, masonry, and hardwood. Common on bench drills, pillar drills, and older corded drills.
Hex Adapter Drill Chuck
A hex adapter drill chuck fits into any drill with a 1/4 inch hex quick-release chuck. It allows you to use standard round-shank drill bits in an impact driver or screwdriver. Very handy when you want to switch between driving and drilling on the same tool.
SDS-Plus Adapter Chuck
An SDS adapter chuck fits onto an SDS-plus rotary hammer drill. It converts the SDS fitting to accept standard round-shank bits. This saves you needing a second separate drill for regular drilling jobs.
Self-Tightening Chuck
A self-tightening chuck grips tighter as torque increases. It reduces bit slippage during heavy drilling. Useful for drilling concrete, brick, and dense timber. Less common but worth considering for demanding site use.
Replacement Brand-Fit Chucks
These are chucks made to replace the original on branded drills. Options include parts that are compatible to replace a DeWalt drill chuck or replace a Milwaukee drill chuck. Always check the thread size and spindle spec before buying.
How to Replace a Drill Chuck on a Cordless Drill
Replacing a drill chuck is a straightforward task. You do not need specialist tools for most standard drills. Here is how to do it safely.
Step 1. Open the jaws of the old chuck fully. Look inside for a retaining screw at the base of the jaws. This screw has a left-hand thread. Turn it clockwise to remove it. Not all drills have this screw. Check before you start.
Step 2. Insert a hex key or Allen key into the chuck jaws. Tighten the chuck firmly onto the key. Give the key a sharp anti-clockwise strike with a mallet or tap against a workbench. This will unscrew the chuck from the spindle.
Step 3. Thread the new chuck onto the spindle by hand. Turn it clockwise until it is fully tight. Refit the retaining screw if your drill has one. Turn it anti-clockwise to tighten (left-hand thread).
Important: Always disconnect the drill from its battery or power source first. Work on a stable, flat surface. If the chuck is very tight, hold the drill body firmly in a vice with soft jaws.
How to Pick the Right Replacement Drill Chuck
Getting the right chuck depends on three key things. These are: thread size, chuck capacity, and chuck type.
Check the Spindle Thread
The spindle thread must match the new chuck exactly. Common sizes are 1/2 inch by 20 UNF and 3/8 inch by 24 UNF. Some brands use metric threads. Always check your drill's manual or the old chuck markings.
Check the Chuck Capacity
Chuck capacity is the maximum shank diameter it can hold. Most DIY drills take up to 10mm or 13mm shank bits. Trade drills and bench drills often need a 16mm or larger capacity chuck.
Keyed vs Keyless
Keyless chucks are faster to use for everyday work. Keyed chucks grip harder and suit heavy drilling tasks. Match the type to how you will use the drill most often.
Using an Adapter Instead
If you just want to use different bit types on your drill, an adapter may be enough. A hex adapter drill chuck lets you use round-shank bits in an impact driver. This avoids the need to replace the full chuck assembly.
Brand Compatibility
Many chucks are universal if the thread matches. However, some brands like DeWalt and Milwaukee use specific thread sizes. Always verify before ordering to avoid returns or wasted time.
Drill Type Matters
SDS-plus drills need a separate adapter chuck to use standard bits. Combi drills and driver-drills use standard threaded chucks. Pillar drills and bench drills use keyed chucks with Morse taper or JT33 arbors.
Common Drill Chuck Thread Sizes
Use this table as a quick guide when ordering a replacement chuck. Always confirm with your drill's manual or the markings on the old chuck.
| Thread Size | Common Drill Types | Notes |
|---|---|---|
| 3/8 inch by 24 UNF | Light cordless drills, compact driver-drills | Very common on smaller 10.8V and 12V drills |
| 1/2 inch by 20 UNF | Full-size cordless drills, heavy corded drills | Standard on 18V and 20V DeWalt and Milwaukee drills |
| 1/2 inch by 16 UNF | Some older UK and European corded drills | Less common but still found on certain Bosch models |
| B16 (Morse Taper) | Bench drills, pillar drills, drill presses | Requires a matching arbor and chuck key |
| 1/4 inch hex shank | Impact drivers, screwdrivers | Needs a hex adapter drill chuck to accept round-shank bits |
If you cannot find the thread marking on your drill, measure the spindle diameter. A 10mm spindle usually takes a 3/8 inch thread. A 14mm spindle usually takes a 1/2 inch thread.

Frequently Asked Questions
How do I know what size drill chuck I need?
Check the thread markings stamped on the side of your old chuck. Common sizes in the UK are 3/8 inch by 24 UNF and 1/2 inch by 20 UNF. If unmarked, check your drill's manual or measure the spindle diameter.
Can I replace a DeWalt drill chuck myself?
Yes. Most DeWalt cordless drills use a 1/2 inch by 20 UNF threaded chuck. You need a hex key, a mallet, and sometimes a small flat-head screwdriver for the retaining screw. The job takes around 10 to 15 minutes on most models.
What is a hex adapter drill chuck used for?
A hex adapter drill chuck fits into the 1/4 inch hex receiver of an impact driver or screwdriver. It allows you to use standard round-shank drill bits in the tool. This is useful when you want to drill and drive without switching tools.
Is replacing a Milwaukee drill chuck the same as other brands?
The process is similar but the thread size may differ by model. Milwaukee 18V drills typically use a 1/2 inch by 20 UNF thread. Always confirm the thread before purchasing a replacement chuck.
What is the difference between a keyed and keyless drill chuck?
A keyed chuck requires a T-key to tighten the jaws. It grips more firmly. A keyless chuck tightens by hand and allows faster bit changes. Keyed chucks suit heavy work. Keyless chucks are better for everyday use.
Will a replacement chuck fit any drill brand?
Only if the spindle thread matches. Thread size varies between drill brands and models. A chuck with the correct thread will fit regardless of brand name.
Can I use a standard drill chuck on an SDS drill?
Not directly. You need a specific SDS adapter chuck to accept standard round-shank bits. This adapter slots into the SDS fitting and then holds regular drill bits. It does not allow hammer action, so use it in rotation mode only.
