Zero Flute Countersink Sets — Chatter-Free Deburring & Countersinking Kits

The Zero Flute Countersink Sets collection includes professional countersink kits engineered for smooth, chatter-free deburring and precise countersinking across a wide range of hole sizes and materials. Featuring Champion’s proven zero flute cutting geometry, these sets are designed for users who want versatility, consistency, and clean finishes without switching between individual tools.

Zero flute countersinks maintain continuous cutting contact with the workpiece, eliminating vibration, reducing grabbing, and producing superior surface finishes—especially on thin materials and softer metals. These characteristics make zero flute countersinks ideal for finishing operations, flat-head fastener seating, and edge breaking.

This collection includes shop-ready and job-site-ready sets such as the CSK-SH-SET for hex shank and impact driver use, along with CSK-SET-1 and CSK-SET-5 for expanded size coverage in fabrication, maintenance, and assembly environments.
