Cork tears and compresses easily, so a sharp centre point and light feed pressure matter more than raw drilling power. Brad-point bits are the sensible first choice for small holes; Forstner bits are the better alternative for wide, flat-bottomed recesses. Back the cork with scrap wood, run a test hole, and do not use a worn twist bit that can grab and shred the edge.

Buying tips
- For small holes, begin with a sharp brad-point bit; for wide recesses, step up to a Forstner bit.
- Clamp cork against a scrap-wood backer and reduce feed pressure as the bit exits.
- Test on an offcut first because cork density and adhesive-backed sheets behave differently.
