How to use a hinge drill bit

Updated: 23 October 2026

You have a sprung guide in the chuck and a butt hinge on the bench. The nose has to be seated before the drill starts, and the sleeve will not cut a full-length hole for a 30 mm screw. Seat it, drill square, clear the dust, and stop when the job is no longer scrap. Which set to buy stays on the [hinge drill bit comparison](/hub/drilling-and-accessories/hinge-drill-bit).

What the sleeve is for

The tapered nose sits in the countersink already in the hinge or the lock plate. The spring holds that nose while a small bit drills on the same centre. You are not aiming at a pencil cross. The leaf is the template, after you have placed it. The sleeve is a short starter. Trend reviews say the pilot stops early, and the listing prints no travel distance. FAMAG lists about 9 mm and 10 mm on similar guides, which is that maker’s figure, not a rule here. A 30 mm screw still needs an ordinary bit of the same diameter. Hammer mode walks the nose out of the countersink, even when a bullet says the hex fits an impact driver.

Drill one pilot

Clamp the door or the frame, and wear eye protection. At work the drill is work equipment under PUWER 1998: suitable, maintained, and used by trained people. At home the same habits still matter, because a small bit grabs when the nose is only half in the hole. Choose the guide that matches the screw in that packet. Seat the nose fully in the countersink with the drill still. If you can see a gap, a spinning bit will walk. Start slowly in rotary mode, keep the drill square, and let the sleeve compress. Withdraw straight out, still turning slowly. Drive one screw by hand before you drill the rest of the leaf. If the head sits proud or off to one side, stop.

When it clogs or stops short

Sawdust packs the windows, especially in oak. The spring fails to return, the bit stays proud, and the next hole leaves the centre. Stop, clear the side gaps, and check that the sleeve slides. Trend and Ancable reviews both describe this seizure. A short hole can still be the right start. Follow with a twist bit of the same diameter. KAHEIGN’s listing says to stay around 2,000 to 3,000 rpm or the bit will run off centre, break or jam. That note is the seller’s, not an HSE limit. Stop if the sleeve will not compress or the bit snaps.

When to put the drill down

A certificated fire door is not scrap. The British Woodworking Federation treats hinges as essential hardware on that assembly. The DHF and GAI code points timber fire-door hinges to EN 1935, with screws not smaller than No.8 and not shorter than 30 mm unless the certificate says otherwise. A self-centring bit does not make an unapproved hinge or a short screw acceptable. Stop as well for glass, for rated metal, and for a finished door you cannot replace. Boring distance and cup depth belong on the 35 mm hinge drill bit page.

Common questions

Do I mark the hole or sit the bit in the countersink?
Sit the nose in the countersink. The hinge or the lock plate is already the template. A pencil mark is only for placing the leaf, not for aiming the bit. If you start on a mark beside the leaf, you have thrown away the only jig the guide has.
How deep will the sleeve go?
Often only a starter. Trend reviews say the sleeve stops early, and the listing does not print a travel figure. FAMAG quotes about 9 mm to 10 mm on its own guides, which is that maker’s tip. Finish a 30 mm hinge screw with a twist bit of the same diameter.
What do I do when the sleeve sticks?
Stop, withdraw the guide, and clear the dust windows before you drill again. Oak is the usual culprit. If the sleeve still will not return, or the spring has collapsed, that guide is finished for the day. Do not keep the drill running in the hope that speed will free it.
Should I use an impact driver or hammer mode?
Use rotary mode if the 1/4 inch hex fits. A listing that names an impact driver is talking about the shank. Hammer mode knocks the nose out of the countersink. If the hex will not seat, change the chuck or the guide.
How do I know the pilot is centred?
Drive one screw before you drill the rest. The head should sit in the middle of the countersink. A head on one rim means the nose was not seated or the bit is the wrong size.
When do I stop and call a joiner?
Stop for a certificated fire door, for glass or rated metal, or if a mistake would scrap a finished leaf. Also stop if the bit has snapped or the hinge will not sit flush. An ordinary softwood internal door is the job this method is for.
Does this method cut a 35 mm cup?
No. The spring guide is a few millimetres across. A concealed cabinet hinge needs a 35 mm recess to a depth on that hinge’s sheet. This method on a cabinet door gives you a screw pilot and no cup. A plastic fence is not the drawing.
