Champion CSK-18SH 82° Zero-Flute 1/4" Hex Shank Countersink | No. 10-12-14 Screws — Pilotless Hex-Shank Deburring Tool
The CSK-18SH is an exact 82° pilotless zero-flute countersink with a 1/4" hex shank for No. 10-12-14 screws. Its single cutting edge is designed for fast stock removal, clean chamfering and controlled deburring without a separate pilot.
This short, impact-ready Champion CSK-SH countersink fits compatible impact drivers, portable power drills and drill presses. The 1/4" hex shank supports quick tool changes, while the zero-flute geometry helps produce a chatterless finish in metal, plastic, wood and aluminum when the tool is used correctly.

Why Choose a Zero-Flute Hex-Shank Countersink?
The pilotless, single-edge design removes material quickly and supports a smooth finish across the specified No. 10-12-14 screw-size group. The 1/4" hex shank is made for fast changes in impact drivers and portable drills, without adding a bulky adapter to the setup.
