What is a drill-in hinge?
A drill-in hinge is a hinge whose cylindrical parts are inserted into a drilled hole in the door edge and in the frame. Because the hinge disappears into the timber, only the knuckle (the pivot point) shows, or the hinge is fully hidden when the door is closed. It is also called an insert hinge or barrel hinge.
Application
Drill-in hinges are used where a clean, discreet look is wanted:
- Internal doors — a concealed hinge gives a smooth, modern appearance without surface-mounted leaves.
- Furniture and cabinet doors — the cylinders are small and vanish into the edge of the panel.
- Renovation — handy when an old hinge hole needs to be reused or hidden.
Fitting
The cylinders need an accurately drilled hole with the right diameter and depth, so drill with a stop or a drill stand to keep the door and frame in line. A small error already causes binding or a sagging door. Many drill-in hinges can be adjusted in three directions after fitting, which makes hanging easier. Choose the hinge size and number of hinges to suit the door weight: a heavy door needs three sturdy hinges.
Depending on quality and finish, the price is usually between a few euros and a few tens of euros each. For external doors, choose a corrosion-resistant version and a certified type where security is required.
