Description
Version:
Corrected thread profile for milling exact internal threads (ensure stable clamping conditions). Incorporating a countersink profile for a 90° countersink. A stronger core diameter, two narrow geometrically optimised chip flutes and a special drill point result in good chip formation and low cutting pressure.
Advantage:
Drilling, countersinking and thread milling all with a single tool!
