About Single Flute Countersinks

Single flute countersinks produce excellent results for light burr-free countersinking operations, are excellent at small hole chamfers, can operate at slightly higher RPM and may be reground many times. The positive shear cutting edge suits non-rigid machining setups and machines with less than precision spindles. Countersinks larger than 1" are not pointed but have flat ends.

Available in premium M2 High-Speed Steel and Carbide.
