Drill Bit Stuck? Here’s How To Get It Out

You’ve finished drilling and the bit won’t come out. The chuck turns but the bit stays put. Or the collar won’t pull back at all. Or the bit snapped and half of it is still inside.

Here’s the thing most people get wrong: a stuck bit is almost never a broken chuck. The chuck is a simple mechanical device with very little to fail. What fails is the interface between the chuck and the bit — a burr on the shank, debris packed into the jaws, or a mechanism that’s seized. The tool is fine. The bit and the chuck are just stuck together.

That means the fix is usually free, and it usually works. There are six techniques, and the order matters — start with the easiest and stop when the bit releases.

For the complete procedure with every technique and the retention-screw step that most people miss, see the guide linked at the bottom.

Quick Checks Before You Reach For Tools

Run through these first. They cost nothing, and they resolve a surprising number of jams.

• Is the tool de-energised? Remove the battery or unplug it. A drill that spins while your hand is on the chuck will break fingers.
• Which type of chuck do you have? Keyless (three jaws, hand-tightened), keyed (uses a chuck key), or an impact driver (hex quick-release). The release procedure differs.
• Can you see a burr on the bit shank? Look at where the shank enters the jaws. Raised metal on the edge means the shank has deformed and is catching in the jaw tracks.
• Is the chuck fully open? Sometimes the bit is just seated deeper than you think, and opening further releases it.
• Has the bit spun in the chuck before? If it slipped under load, the shank has almost certainly burred.
• Was the bit over-tightened? If you tightened by holding the chuck and pulling the trigger, the jaws are driven deeper than hand-tightening.
• Is there rust or debris visible? Shine a torch into the gap between the jaws and the bit.

If none of those resolve it, work through the techniques below in order.

1. Penetrating Oil

Why it works: most stuck bits are seized by rust, debris, or dry jaws. Penetrating oil softens and loosens all three. It’s the single most effective method for a seized mechanism.

Symptoms it solves:

• Chuck collar won’t turn
• Chuck turns but the jaws don’t move
• Impact driver collar won’t pull back
• Bit stuck after the tool has been stored for a while

How to do it:

1. Remove the battery or unplug the drill.
2. Spray penetrating oil into the gap between the chuck jaws and the bit — from the front, from the sides, and from below if you can get at it.
3. For a keyless chuck, also spray into the collar mechanism where the two halves rotate against each other.
4. For an impact driver, spray into the collar opening and the bore from the bit side.
5. Let it sit for 10 to 15 minutes. The oil needs time to penetrate.
6. Try the release again — turn the collar, or pull the collar back and pull the bit.
7. If it doesn’t release, apply more oil and leave it an hour.

Cost: $5 to $15 for the oil.

2. The Tap Method

Why it works: vibration frees mechanisms that oil alone can’t reach. The shock breaks the bond between the seized surfaces.

Symptoms it solves:

• Seized jaws that oil didn’t free
• Stuck ball detent in an impact driver
• Debris binding the mechanism

How to do it:

1. Remove the battery or unplug the drill.
2. Hold the drill body firmly in one hand.
3. With a rubber mallet or a wooden block held against the chuck, tap the chuck firmly and repeatedly in the direction the jaws need to move.
4. For a keyless chuck, alternate taps on the top and bottom of the chuck body.
5. For an impact driver, tap the chuck body from the side, not from the bit end.
6. After 10 to 15 taps, try the release again.
7. Repeat if it doesn’t release first time.

Important: use a rubber mallet or a wooden block. Never use a metal hammer — you’ll crack the chuck.

Cost: $0.

3. The Two-Plier Method

Why it works: the technique that resolves most burred shanks. By gripping the bit and the chuck separately and twisting in opposite directions, you can overcome the burr that’s catching in the jaw tracks.

Symptoms it solves:

• Chuck opens but the bit won’t release
• Burred shank visible at the jaw line
• Bit turns in the chuck but won’t come out

How to do it:

1. Remove the battery or unplug the drill.
2. If the chuck will open — even partially — open it fully.
3. Grip the bit shank with a pair of locking pliers. Grip it firmly, close to the chuck jaws.
4. Grip the chuck body with a second pair of locking pliers. Grip on the chuck body itself, not the collar.
5. Hold both pliers and twist in opposite directions — the bit one way, the chuck body the other.
6. Use a steady turning force, not a sudden yank.
7. If the bit starts to move, keep twisting gently.

For an impact driver: use one pair of locking pliers on the bit, pull the collar back with your other hand, and twist the bit as you pull.

Be careful not to crush the bit with the pliers. The goal is a firm grip, not further deformation.

Cost: $0.

4. Chuck Removal

Why it works: if the bit won’t release with the chuck in place, taking the chuck off lets you work on it directly — and the bit can often be pushed out from behind once the chuck is off the spindle.

Symptoms it solves:

• Bit stuck with a seized chuck
• Chuck won’t turn at all
• Any case where the techniques above have failed

How to do it — keyless chucks:

1. Remove the battery.
2. Open the chuck jaws fully so the internal screw is visible at the bottom of the jaw opening.
3. Look inside. Most keyless chucks have a left-hand thread retention screw. Turning it clockwise loosens it. Turning it counter-clockwise tightens it.
4. With a screwdriver that fits the screw head, turn the screw clockwise to remove it. This is often the hardest step — these screws are frequently seized.
5. Once the screw is out, the chuck unscrews from the spindle. Grip the chuck body with locking pliers, put an Allen key in the jaw opening, and turn the Allen key counter-clockwise while holding the chuck.
6. Once off, the chuck can be soaked in penetrating oil and the jaws freed, or replaced.

How to do it — keyed chucks:

1. Remove the battery.
2. Open the jaws fully.
3. Remove the screw at the bottom of the jaw opening (often left-hand threaded).
4. The chuck unscrews from the spindle. Hold the spindle still with locking pliers padded with cloth, and turn the chuck counter-clockwise.

The retention screw is the step most people miss. If your chuck won’t come off with the usual method, look inside the jaw opening for the screw — it’s almost always there, and it’s almost always left-hand threaded.

Cost: $0.

5. Impact Driver Collet Release

Why it works: impact drivers use a ball detent and collar rather than jaws. The release technique is different, and disassembly is possible on most tools.

Symptoms it solves:

• Collar won’t pull back
• Bit moves a few millimetres but won’t release
• Detent ball visibly seized

How to do it:

1. Remove the battery.
2. Pull the collar fully back and hold it. If the bit moves freely, the bit groove is the issue — the ball is retracting but the groove is burred.
3. If the collar won’t pull back at all, the collar mechanism is seized. Apply penetrating oil and leave 10 to 15 minutes.
4. Pull the collar back and push the bit inward slightly before pulling it out. The pressure relief sometimes releases the ball.
5. If it still won’t release, the collar assembly can be disassembled on most tools. Look for a retaining ring or snap ring holding the collar together, and work it out carefully with a flat-blade screwdriver. It’s spring-loaded and will fly across the room.

Cost: $0 to $15 for oil.

6. Drilling Out A Snapped Bit

Why it works: the last resort, and only needed if the broken piece can’t be gripped with pliers. A screw extractor bites into a drilled pilot hole and backs the broken piece out.

Symptoms it solves:

• Bit snapped off inside the chuck
• Piece is flush with or below the jaw line
• Locking pliers can’t grip the piece

How to do it:

1. Remove the battery.
2. Open the chuck fully.
3. If the broken piece protrudes even slightly, try locking pliers first. A snapped bit often comes out with gentle twisting.
4. If it doesn’t, you’ll need to drill into it. This is the one step where you cannot use the tool the bit is stuck in. Use a separate drill.
5. Select a drill bit smaller than the stuck piece. Hardened bits can’t be drilled with a normal HSS bit — you’ll need a carbide or cobalt bit if the stuck bit is hardened steel.
6. Wear safety glasses. Metal shavings travel fast.
7. Apply cutting oil and drill slowly into the centre of the broken piece.
8. Insert a screw extractor into the hole. Turn it counter-clockwise to bite into the broken piece.
9. Turn the extractor counter-clockwise until the broken piece comes free.

Cost: $10 to $25 for a screw extractor set. $5 to $15 for a carbide or cobalt drill bit.

Repair or Bin? Repair, unless the piece is so deep that the chuck needs replacing.

Which Symptom Points To Which Method

Prevention: How To Stop It Happening Again

The reason bits get stuck is almost always one of three habits. All three are free to change.

• Don’t spin-tighten the chuck. Hand-tighten a keyless chuck. Don’t hold the chuck and pull the trigger — it drives the jaws into the shank and burrs it.
• Don’t over-tighten keyed chucks. The chuck key should be snug, not forced.
• Keep the chuck clean and dry. Wipe the jaws after use, and don’t store the tool with the chuck closed against a bit for months.

One more worth knowing: inspect bits regularly. A burred shank is a bit that’s about to jam. Replace any bit with visible deformation before it sticks.

Repair vs Replace: The 50% Rule

If the repair costs more than 50% of the price of a comparable replacement, replacement makes more sense.

New drill cost: $50–$150 for consumer tools; $150–$400 for pro tools.

When to repair: the fault is a burred shank, seized mechanism, or replaceable chuck — which covers most cases — and the tool is under eight years old.

When to bin: a seized chuck on a budget drill past seven years, or a stripped ring gear where the chuck can’t be removed from the spindle.

The reassuring part: releasing a stuck bit is free in the majority of cases. A tool replacement is only a consideration when a component has genuinely failed.

What You Can Safely Do Yourself

Safe DIY:

• Penetrating oil and the tap method
• The two-plier method
• Push-in-then-pull on an impact driver
• Chuck removal, including the retention screw
• Impact driver collet disassembly
• Drilling out a snapped bit with a screw extractor
• Chuck replacement

Technician recommended:

• Removing a chuck that’s welded to the spindle by rust
• Stripped ring gear where the chuck can’t be removed
• Any repair to the drill’s internal mechanism

Safety note: remove the battery or unplug the tool before any work. Do not strike the chuck with a metal hammer — use a rubber mallet or a wooden block. Penetrating oil is flammable; use it in a ventilated area. Wear safety glasses when drilling out a snapped bit.

FAQ

How do I get a drill bit unstuck?
Penetrating oil first, leave 10 to 15 minutes. Then tap the chuck with a rubber mallet. Then the two-plier method — one pair on the bit, one on the chuck, twist in opposite directions. Those three resolve the majority of cases for free.

Why is my drill bit stuck in the chuck?
Usually a burred shank. The bit spun in the chuck at some point, and the hardened steel deformed against the jaws. The burr now catches in the jaw tracks.

Why won’t my DeWalt drill chuck release the bit?
Same reason as any other — burred shank, debris, or over-tightening. DeWalt chucks are standard three-jaw, so the same techniques apply. Some models have a spindle lock that helps.

How do I release a bit from an impact driver?
Pull the collar fully back and hold it, then push the bit inward slightly before pulling it out. If it doesn’t release, tap the bit sideways with a punch, or apply penetrating oil and wait.

Can a stuck bit damage the drill?
Not directly — the drill doesn’t know the bit is stuck. But forcing a seized chuck can strip the ring gear on a keyed chuck, or crack the collar on a keyless one. If the chuck won’t turn with moderate force, apply oil and wait rather than forcing it.

What if the bit snapped off inside?
Try locking pliers if any part protrudes. If it’s flush or below the jaws, you’ll need a screw extractor — drill a small pilot hole and back the piece out.

Can I replace the chuck myself?
Yes, on most drills. There’s a retention screw inside the jaw opening (often left-hand threaded), and once it’s out, the chuck unscrews from the spindle.

Is it worth repairing a drill with a stuck chuck?
Almost always, yes. Releasing a stuck bit is free in most cases, and a replacement chuck is $20 to $60 — well under the 50% line on any drill under ten years old.
