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.

Hex Shank for Power Tools

Phillips

Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.

Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

High-Torque Phillips Bits

Hex Shank for Power Tools

Phillips

Less likely to crack or break apart under high torque than standard bits, these are often used with power tools to install machine screws.

Diamond-coated bits have better wear resistance than uncoated bits.

Quick-Change Combination Countersinking
Drill and Screwdriver Bit Sets

Fasten differently sized screws with these sets. They save you the effort of switching three separate bits in and out of a power tool, instead letting you flip between a countersinking drill and a screwdriver bit with a single hand. You can also attach your own countersinking drills and screwdriver bits as long as they have a 1/4” hex shank.

Countersinking drills have an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.

Countersinking Drill and Screwdriver Bits

Drill, countersink, and drive screws without switching three separate bits in and out of your power tool. With a single hand, flip between drilling countersunk holes and driving screws. The countersinking drill and screwdriver bit are secured with set screws, so you can switch them out for any bits with a 1/4” hex shank.

The countersinking drill has an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.
