A cordless drill can remove many stripped screws, but the wrong bit, speed, or pressure can make the damage worse. Start with the simplest method that fits the screw, then move to extraction tools only if needed. The goal is to keep the drill straight, protect the surrounding material, and stop before the screw head breaks off.
What we cover
Check the screw and the workpiece
Clear away paint, dirt, or debris so you can see the screw head. Identify the drive type—Phillips, square, Torx, or another shape—and use a bit that fully fits it. A bit that wobbles or sits proud is more likely to slip. If the head is badly rounded, a larger bit or a different extraction method may be needed.
Check what the screw is holding and what lies behind it. In wood, a small amount of surrounding damage may be acceptable; in a metal panel, cabinet face, or finished surface, it may not be. If the screw is in a wall, avoid drilling until you know there are no wires or pipes behind it. Wear eye protection, especially when drilling metal or using an extractor.
Try a fitting bit first
Seat a fresh, correctly sized bit firmly in the screw head. Set the drill clutch low enough to reduce the chance of driving past resistance, and select a slow speed. Keep the drill square to the screw and press firmly along its axis. Use short trigger pulls rather than a long burst. If the bit starts to climb out of the recess, stop; continuing will round the head further.
A manual screwdriver can be a better first choice for a small screw or delicate work because it gives you more feel. For a larger, accessible screw, the drill is useful once the bit has a solid grip. If the head is only slightly worn, a fresh bit may be all that is needed.
Improve grip on a lightly stripped head
For a shallowly damaged Phillips head, try a slightly larger Phillips bit or a compatible bit with a tighter fit. Do not force a bit into the recess if it does not seat fully. A wide rubber band between the bit and screw can add friction, but it is a low-cost try, not a dependable extraction method; it usually fails when the recess is badly rounded or the screw is tight.
If the screw head stands above the surface, locking pliers may grip its outside edge more reliably than a drill. Clamp them tightly and turn slowly. This works best when the head is accessible, but can mar the head and nearby finish.
Choose an extraction method
When ordinary bits slip, use a method suited to the screw’s condition and location. A dedicated screw extractor can bite into a drilled pilot hole; a left-hand drill bit may catch and turn the screw out while drilling. Extractors are useful but brittle, so forcing one can snap it off in the screw and make the job much harder. Follow the tool’s instructions, and use a drill with a controllable low-speed setting.
For occasional repairs, a basic screw extractor set is usually a more appropriate purchase than a specialized powered tool. Check that the set includes sizes suitable for your screw diameter and that your drill can hold the required bit. Very small screws may call for precision hand tools instead.
| Method | Best for | Main trade-off |
|---|---|---|
| Correct replacement bit | Lightly worn drive recess | Quick and inexpensive, but won’t grip a rounded head |
| Rubber band or gripping material | Minor damage on a low-torque screw | Cheap, but unreliable under higher load |
| Locking pliers | Raised head with accessible edges | Can damage the finish and needs room to turn |
| Extractor or left-hand bit | Badly damaged head when other methods fail | More controlled, but requires careful drilling and can break if forced |
Drill a pilot hole for an extractor
Choose an extractor matched to the screw size; the package should specify the pilot-hole diameter. Use a center punch, if available, to mark the middle of the screw head. This helps keep the drill from wandering. Fit the specified drill bit, set the drill to low speed, and drill straight into the screw head only as deep as the extractor instructions require. Keep the bit centered and clear metal chips as needed.
Some extractors use a separate drilling bit and extraction end; others are designed for a particular sequence. Follow the set’s directions rather than guessing at the hole size. If the bit walks off-center, stop and correct it before the hole grows. A hole drilled too wide can leave too little material for the extractor to bite.
Fit the extractor and turn it in the stated direction, often counterclockwise, using low speed or a hand tool as directed. Apply steady pressure, not a sudden burst. If it does not bite, stop rather than increasing drill speed or leaning harder. Recheck the hole size and alignment. A broken extractor is hard metal and difficult to drill through with ordinary bits.
Use the right drill setting
A standard cordless drill is generally enough for removing a screw. Select low gear and a low-to-moderate speed, keep the tool aligned, and use the clutch where it helps limit torque. An impact driver can deliver strong bursts of rotational force, but those bursts can worsen a damaged recess or break a small extractor. It is not the first choice for delicate extraction.
If you need a drill or bits for other fastening and repair work, compare a cordless drill-driver kit with your current setup. For this task, a costly drill is rarely necessary; controllable low speed and a secure bit fit matter more than maximum power. Hammer mode is for masonry drilling and should be off when working on a screw.
Know when to stop
Stop if the screw head begins to deform further, the bit repeatedly slips, the extractor twists without turning the screw, or the drill heats the workpiece. Repeated attempts can turn a removable screw into a broken fastener or enlarge the surrounding hole. If the screw is in a valuable finished surface, near wiring, or embedded in hard metal, a repair shop or experienced tradesperson may be safer than improvising.
After removal, inspect the hole and replace the screw with the right size and drive type. For wood, a damaged hole may need a properly sized plug or filler before refastening. Use a fresh bit that matches the replacement screw, keep the drill straight, and stop when the head is seated rather than driving it hard into the material.
