Description

Four Flute

Countersinks

 

High Speed Steel

Treated (Black Oxide)

 

Often called "machine countersinks"

 

For chamfering, deburring, and countersinking. The longer shank length is ideal for use in turret lathes for screw machine work.

Four flutes allow higher feed rates than single flute countersinks and greater chip clearance than six flute countersinks.

Black Oxide increases wear resistance, reduces galling and chip welding, improves chip flow and increases lubricant retention.
