3-flute countersinks are designed for general purpose work.

The 3/4" and 1" countersinks have 1/2" shank. The 1/2" countersink has a 3/8" shank and the 1/4" & 3/8" countersinks have a 1/4" shank.

These countersinks are suitable for enlarging and beveling holes, typically for countersinking screw heads. They may also be useful in chamfering edges and corners of holes, and deburring sharp edges or burrs.

Timothy J. ★★★★★

I needed a good set for flattening screw heads on a cabinet job, and the three-flute design on these cuts cleanly without chattering. The 1/2" shank on the larger two bits gives a solid, wobble-free feel in my drill press.

Eli V. ★★★★★

The 1/4" countersink with its 1/4" shank cut through some oak trim like butter, leaving a perfectly clean chamfer. It’s a solid set that covers most common sizes without feeling cheap.

Julian ★★★☆☆

The three-flute design cuts pretty clean in softwood, but I found the 1/2-inch shank on the larger sizes wobbles slightly in my drill press. Fine for light use, though the set covers most common screw sizes.
