To stop stripping screws, use the exact bit profile and size that fits the screw head, hold the tool square to the fastener, keep steady pressure along the screw’s axis, and start slowly. On a drill/driver, begin with a low clutch setting and raise it only until the screw reaches the intended depth. On an impact driver, feather the trigger and use a lower-speed or precision mode when available. Release the trigger as soon as the head is flush or the planned depth is reached.
Neither tool is strip-proof. A worn bit, poor fit, excessive torque, a pilot hole that is too small, or a workpiece that moves can damage the head even when the tool is functioning normally. The procedures below show how to choose the tool, set it up, drive the screw, and recover when something starts to go wrong.

Why screw heads strip
Stripping (also called cam-out) happens when the driver bit loses full contact with the recess in the screw head. The bit then rides up the angled surfaces, rounding the recess or damaging the bit. The usual causes are related:
- Wrong profile or size: A Phillips bit in a Pozidriv recess, or a bit that is too small, contacts only part of the recess.
- Bit held at an angle: Side loading lets the bit climb out instead of pushing into the recess.
- Insufficient axial pressure: If you do not press in line with the screw, the bit can bounce out as torque rises.
- Too much speed or torque: A fast start or an aggressive clutch setting can spin the head before the threads are seated.
- Worn or damaged accessories: Rounded bit tips cannot transmit torque reliably, even when the profile is correct.
- Material resistance: A hard knot, dense material, or an undersized pilot hole can require more torque than the screw head can tolerate.
- Moving work: A board that shifts or a part that is not clamped makes it difficult to keep the tool square.
The fix is not simply “use an impact driver.” The bit, screw, material, tool setting, and your technique all determine whether the recess survives.

Choose the right tool for the job
| Consideration | Drill/driver with clutch | Impact driver |
|---|---|---|
| How torque is delivered | Continuous rotation, limited by the adjustable clutch when screwdriving | Rotational hammering pulses that can deliver substantial force |
| Control for delicate work | Generally straightforward to set for repeatable seating | Requires careful trigger control; use a lower-speed or precision mode if the model provides one |
| Typical advantage | Controlled driving of smaller fasteners and repeated assemblies | Longer or more demanding screws where extra rotational force is useful |
| Main stripping risk | Clutch set too high, speed too high, or bit allowed to cam out | Impact force and speed used after the screw has seated, or trigger squeezed too aggressively |
| What the manual controls | Torque-collar numbering and clutch behavior vary by model | Speed, impact, and precision modes vary by model |
A clutch-equipped drill/driver is often the easiest choice for cabinet hardware, trim, electronics enclosures, and other work where screw depth must be consistent. An impact driver can be the better choice for long structural screws or stubborn fasteners, but its additional force does not compensate for a poor bit fit or a crooked tool.
Manufacturer descriptions characterize impact drivers as tools that combine rotation with hammering action for screws and bolts. That describes the operating principle, not a promise that every impact driver is safer for screw heads than every drill/driver.
Prepare before you pull the trigger
Match the bit to the recess
- Read the screw packaging or inspect the head to identify the profile (for example, Phillips, Pozidriv, Torx, hex, or another system).
- Select the size that fills the recess without forcing it. The bit should sit fully down in the head with minimal side-to-side movement.
- Replace a tip that is rounded, chipped, twisted, or polished from slipping. A new bit cannot repair a recess that is already damaged, so change it before starting a fresh screw.
- For an impact driver, use a bit or bit holder rated for impact use. An impact-rated set is designed for the repeated shock loads; it does not make an incorrectly sized bit fit a different screw profile.
Full, even contact is the goal. If the bit rocks in the recess while the tool is switched off, choose another size or profile rather than trying to compensate with more pressure.

Secure the workpiece and plan the depth
- Clamp or otherwise secure the material so it cannot rotate or slide as the screw enters.
- Mark the intended stopping point. Decide whether the head should be flush, slightly countersunk, or stopped above the surface for a washer or bracket.
- Keep hands clear of the rotating bit and wear eye protection. Follow the safety instructions for the exact tool model.
Securing the work also protects the bit. When a board moves, you may instinctively twist the tool to follow it, which increases the chance of cam-out and reaction torque.
Decide whether to drill a pilot hole
A pilot hole can make a wood screw easier to drive and can help prevent splitting. The appropriate diameter depends on the screw’s design and the material; there is no single size that applies to every wood screw. Use the guidance for your screw and tool, and test on scrap of the same material when possible. A pilot hole that is too small leaves excessive material for the threads to displace, while one that is too large can reduce holding strength.
Step-by-step: driving a screw with a drill/driver
- Install the bit. Tighten the chuck securely and check that the bit is centered. If the bit is not straight in the chuck, it will orbit and make it harder to stay square.
- Select screwdriving mode. Use the clutch or screw icon rather than the drill setting when your model provides one. The drill setting commonly bypasses the torque-limiting clutch.
- Start at a low clutch number. Numbered collars represent a torque range; higher numbers generally allow more torque. The exact values are model-specific. The DCD708/DCD709 manual, for example, advises starting low, advancing as needed, and making practice runs in scrap or an unseen area.
- Place the bit before starting. With the trigger released, seat the tip fully in the screw recess. Keep the drill aligned with the screw’s centerline.
- Apply straight-in pressure. Press firmly enough to keep the bit engaged, but do not lean the tool sideways. Keep both hands positioned so you can resist the tool’s reaction torque.
- Feather the trigger. Begin at low speed. Let the threads start, then increase speed gradually only if the bit remains fully seated.
- Watch the head and surface. As the screw approaches the planned depth, ease off the trigger. Stop when the head reaches the mark; do not continue driving after it is flush or otherwise seated.
- Check the result. If the head is proud, increase the clutch one step and make another controlled pass. If the bit slips, stop, inspect the recess and bit, and replace either one if damaged.
The clutch is a torque limiter, not a depth gauge. Changes in screw length, material, pilot-hole size, and friction can make the same number stop at different depths. For a batch of identical screws, drive one test screw first and use it to establish a setting.

Step-by-step: driving a screw with an impact driver
- Fit an impact-rated accessory. Use the exact profile and size required by the screw. Verify that the holder has locked the bit in place.
- Select the gentlest useful mode. If the tool has speed levels, a precision setting, or a mode intended for small screws, start there. Makita’s T-mode on the XPT02Z is one model-specific example: it downshifts and reduces rotation and impact speed before seating to help limit thread stripping, screw breakage, and work damage. This feature should not be assumed on other models.
- Place the switched-off tool on the fastener. Make sure the bit is fully engaged before pressing the trigger. Bosch safety instructions warn that “Rotating driver tools can slide off the fastener,” so keep the tool aligned and maintain control.
- Use a feather-light trigger at first. Let the initial rotation start the screw. Avoid immediately squeezing the trigger fully; the impact mechanism can deliver force faster than a soft material or small screw can accept it.
- Maintain axial pressure. Keep pushing straight into the screw as the impacts begin. If the bit begins to climb out, release the trigger immediately rather than trying to overpower the slip.
- Release before final seating. As the head reaches the intended depth, let go of the trigger. Impact drivers can continue tightening after the head appears flush, potentially damaging the recess, threads, or work surface.
- Use a test screw. Confirm the mode and trigger technique on scrap or an inconspicuous area made from the same material. Adjust one variable at a time: speed mode, trigger travel, pilot hole, or bit.
The pulsing action is useful for long or demanding fasteners, but it also means the tool can twist opposite the bit as the fastener seats or is removed. Brace the tool without placing fingers near moving parts, and follow the model manual’s instructions for reaction torque.

How to set a drill clutch without stripping screws
Start low, then increase gradually
There is no universal “correct” clutch number. A low number permits less torque; a higher number permits more, but the scale and actual torque differ among tools. Start at the lowest setting that might drive the screw, then increase one step at a time until the screw reaches the intended depth.
Use a repeatable test
- Use a spare screw and a piece of matching scrap.
- Drive until the clutch slips or the screw stops short.
- Raise the setting by one increment and repeat.
- Stop at the lowest setting that consistently reaches the target depth without crushing the surface.
Test again when you change screw length, diameter, coating, material, or pilot-hole size. A setting that works in soft pine may be inadequate in hardwood and excessive in a thin panel.

Know when the clutch is not the problem
If the bit slips before the clutch engages, inspect alignment and fit first. If the head is already damaged, a higher clutch setting will usually make the damage worse. Install a fresh, correctly sized bit and start with a new screw.
Speed, pressure, and stopping technique
Why slow starts matter
Low speed gives the bit time to settle into the recess and lets you detect a poor fit before the head is rounded. Once the screw is tracking straight, a moderate speed can shorten the job, but there is no benefit to maximum speed during the final turns.
How much pressure to use
Use steady pressure along the screw’s axis. Too little pressure allows the bit to bounce out; excessive force can bend the bit, damage the recess, or make it difficult to release the trigger when the screw seats. Keep your wrist aligned with the tool rather than pushing from the side.

When to release the trigger
Release as soon as the screw reaches the planned depth. “One more second” after the head is flush can countersink too far, strip the recess, break a small screw, or compress a soft workpiece. If you need a deeper seat, make a deliberate second pass rather than holding the trigger continuously.

| Symptom | Likely cause | Correction |
|---|---|---|
| Bit jumps out immediately | Wrong profile or size; bit not seated squarely | Stop, compare the bit and recess, fit the correct size, and restart slowly with straight pressure |
| Bit slips near the end | Torque or impact force rises as the head seats; trigger held too long | Use a lower clutch or gentler impact mode, feather the trigger, and release earlier |
| Screw stops proud | Clutch too low, pilot hole too small, or material unusually hard | Check the bit and pilot hole; increase clutch one step or use a controlled second pass |
| Wood splits | No pilot hole, or pilot hole is unsuitable for the screw/material | Back the screw out, assess the damage, and drill a correctly sized pilot hole on the next attempt |
| Tool twists in your hand | Reaction torque or impact action; fastener is binding | Release the trigger, secure the work, reposition both hands, and inspect the screw and hole |
| Recess is already rounded | Continued driving after cam-out or a worn bit | Stop using that bit and screw; try an appropriate extraction method only if the workpiece and fastener allow it |
Recovering a partially stripped screw
- Stop immediately. Continued rotation removes what little recess remains.
- Inspect under good light. Determine whether the damage is limited to the screw or whether the bit tip is also rounded.
- Try a new, exact-fit bit. Seat it firmly and turn at low speed with strong axial pressure. Do not substitute a different profile simply because it appears to fill the opening.
- Reduce the load. If the screw is binding, back it out a fraction, clear debris, or enlarge the pilot hole only when that is appropriate for the material and fastening method.
- Use manual control for the final removal. A hand driver can provide better feel than a powered tool when the recess is marginal.
- Escalate carefully. If the head cannot be engaged, choose a removal method suited to the fastener and workpiece. Protect the surrounding surface and expect that the screw may need replacement.
Do not keep increasing clutch or impact power in an attempt to rescue a damaged head. More torque usually rounds it further.
Safety and control checklist
- Read the exact drill/driver or impact-driver manual before using unfamiliar modes or accessories.
- Wear eye protection, especially when drilling pilot holes or working with hardened fasteners.
- Clamp the workpiece and keep the other hand away from the rotating bit and chuck.
- Check that the bit is locked in the chuck or holder before applying power.
- Keep the tool square and maintain two-handed control when reaction torque is likely.
- Use only accessories rated for the tool’s operating conditions; impact drivers require impact-rated bits and holders.
- Release the trigger before repositioning the bit, changing settings, or setting the tool down.
- Stop if the bit, screw, or material shows unexpected heat, vibration, cracking, or movement.
Choosing accessories and settings for repeatable work
Impact-rated bit sets
An impact-rated screwdriver bit set is useful when you routinely drive screws with an impact driver. Manufacturers design these bits for impact-driver use and may optimize tip geometry to reduce wear, cam-out, and stripping. Those are product-design claims, not a guarantee that a bit will fit every fastener or last a specific number of cycles. Match the profile and size to each screw.
Variable-speed and precision controls
A variable-speed trigger lets you start gently and accelerate only after the screw is tracking straight. Some impact drivers add a precision or “T” mode that changes speed and impact behavior before seating. Because modes differ by model, read the manual instead of assuming that a setting has the same behavior on another tool.
When a clutch-equipped drill is the better investment
If your work involves many small screws, repeated assemblies, or surfaces that are easy to damage, an adjustable-clutch drill/driver offers a simple way to limit torque. It still requires a correct bit, straight alignment, and a controlled stop; the clutch cannot compensate for cam-out caused by a poor fit.
A practical decision guide
Use a drill/driver when
- You need consistent depth across many similar screws.
- The fasteners are small or the material is easy to damage.
- You want to tune torque with a clutch and make controlled, non-impacting starts.
Use an impact driver when
- The screw is long or the material demands more driving force.
- You can maintain firm axial pressure and control the trigger throughout the run-down.
- The tool offers a lower-speed or precision mode that suits the fastener.
Use neither powered tool at full speed when
- The screw head is already damaged.
- The workpiece cannot be secured.
- You are unsure of the bit profile or pilot-hole requirement.
In those cases, pause and correct the setup first. The fastest way to finish is usually the method that prevents a stripped head and a damaged workpiece.
Quick Recap
Key points to remember
- Fit matters more than brand: use the exact profile and size, and replace worn bits.
- Keep the bit straight and apply pressure along the screw’s axis.
- Start slowly; on a drill/driver, begin with a low clutch setting and increase only as needed.
- On an impact driver, feather the trigger and use a precision or low-speed mode when available.
- Release the trigger at the intended depth, not after the screw has been driven farther.
- Use a correctly chosen pilot hole in wood when it will ease driving or reduce splitting.
- Secure the workpiece, expect reaction torque, and follow the exact model manual.
