Forstner Bits

Forstner bits bore flat bottomed holes in wood, making them perfect for mortises, hinge recesses and overlapping holes.  Their rim cutting edges leave clean sidewalls and are excellent for drilling at angles.

What are Forstner bits used for?
Forstner bits are designed to drill precise, clean, flat-bottomed holes in wood. They’re ideal for:

  • Cabinetry and furniture making

  • Drilling concealed hinge holes (e.g. 35 mm Euro hinges)

  • Overlapping or angled holes

  • Cutting partial holes near edges without wandering
    Unlike spade or twist bits, Forstner bits produce minimal tear-out, making them the preferred choice for fine woodworking.

How are Forstner bits different from other drill bits?
Forstner bits feature:

  • A center point for accurate positioning

  • A circular rim with sharp cutting edges for smooth walls

  • The ability to drill at angles, into end grain, and create flat-bottomed or overlapping holes
    They cut cleaner and more accurately than hole saws, auger, or spade bits—especially in hardwoods and laminated boards.

How do I use Forstner bits effectively?

  • Use a drill press for best results, especially on harder materials

  • In handheld drills, drill slowly and steadily to maintain control

  • Clear chips often to prevent burning and overheating

  • For deep holes, use a bit extension or multiple passes
    Choose the correct diameter (commonly 10–50 mm), and keep the bit sharp and clean for best performance.
