Product Family Table


For the carbide family of these tools, the three-flute represents the ideal “general purpose” countersink. They have enough chip clearance in the three-flute design for a variety of ferrous and non-ferrous materials, while providing enough strength with the radial relief design to attack hardened materials up to 40Rc.
