Toolex HSS-E Piloted Counterbore Metric 180° - M3.5 M&D while the uncoated surface supportsThe Toolex HSS E Piloted Counterbore Metric 180 M3. 5 is a precision cutting tool designed to create clean, flat bottom counterbores for flush fastener seating. Built for machinists, fabricators, and serious hobbyists, it combines a cobalt enhanced HSS core with a guided piloted design for repeatable accuracy. Material: HSS E (high speed steel with cobalt) for superior strength, wear resistance, and heat tolerance under demanding cutting conditions.
