About Drill Bits

About Masonry Drill Bits

About Countersinks

Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring.

Use with handheld power drills, drill presses, and in hammer drills. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits drill faster and penetrate material with less pressure than rotary-only bits. Also called percussion or impact bits.

Chip-Clearing Round-Shank Masonry Drill Bit Sets for Rotary Hammers

A more controlled chip removal reduces heat buildup, making these bits good for use on brittle material such as block and brick. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

High-Speed Steel Countersink Sets for Screws

Titanium Nitride (TiN)-Coated Steel

Choose fewer flutes for a faster cut or more flutes for a smoother finish. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.

TiN (titanium nitride) coated countersinks last longer and withstand more heat than black-oxide coated or uncoated countersinks.
