Three Flute Countersinks — Balanced Countersinking for Machine & Shop Applications

The Three Flute Countersinks collection features the Champion 799 series, engineered for balanced, controlled countersinking in machining and shop environments. With a three-flute cutting geometry, these countersinks provide an ideal compromise between aggressive material removal and smooth surface finish.

Compared to single flute designs, three flute countersinks offer improved stability and surface finish, while still maintaining better chip evacuation than higher flute counts. This makes the Champion 799 a versatile choice for general-purpose countersinking where accuracy, consistency, and reliability are required.

Manufactured from high-speed steel (HSS), the 799 series is optimized for use in drill presses, CNC machines, and rigid drilling setups. It is widely used in fabrication shops, machine shops, and industrial production for flat-head fastener seating and chamfering operations.
