Zero Flute Countersinks — Chatter-Free Deburring & Precision Countersinking Tools

The Zero Flute Countersinks collection features professional-grade countersinking and deburring tools engineered to deliver smooth, chatter-free finishes across a wide range of materials. This collection includes Champion’s trusted CSK, DBK, and CSKA zero flute countersinks, along with complete countersink sets designed for shop, production, and job-site use.

Unlike traditional multi-flute countersinks, zero flute countersinks maintain continuous cutting contact with the workpiece. This design eliminates vibration, reduces grabbing, and produces a superior surface finish—especially on thin materials, soft metals, and applications where appearance and fastener seating are critical.

This collection also includes essential countersink sets such as CSK-SH-SET for hex shank and impact driver use, as well as CSK-SET-1 and CSK-SET-5 for expanded size coverage in fabrication shops and maintenance environments.

• CSK — Standard zero flute countersinks for smooth deburring and countersinking.

• CSK-SH-SET — Hex shank zero flute countersinks for impact drivers.
