Countersink bits cut a cone-shaped recess so flat-head screws sit flush with or below the surface. Carpenters and cabinet makers use them for neat screw heads, and metal workers use them to deburr drilled holes in steel, aluminium and plastic.
How to choose a countersink bit
- Wood or metal: wood countersinks with a drill bit, such as the Bosch wood drill bit with countersink and the Milescraft CounterBit set, drill the pilot hole and countersink in one step. HSS 90° countersinks like the Diager 504C and Irwin rose countersink are for metal and deburring.
- Shank: hex shanks fit impact drivers and quick-change chucks. Round shanks fit any drill chuck.
- Sets: 3- to 5-piece sets cover the common screw sizes.
