COMBINED DRILL & COUNTERSINKS RADIUS TYPE
M2 HSS
The Special Profile on this tool is more robust than the 60° angle on a regular combined drill & countersink. The radius serves as a protective chamfer, helping to eliminate the risk of breakage and making it easier to locate the center hole on automatic feeding machines. The radius on this tool works well for 60°, 82°, or 90° angle.
