the first microdrill from Kennametal - General purpose SC drill for a wide range of materials
- Marginless design for reduced friction and heat
thus longer tool life - Optimized gashing design for microdrilling ensures free flow of chips in the center of the drill
- Uninterrupted straight cutting lip allows no starting point for wear and enables even distribution of cutting forces for longer tool life in all materials and less chipping on cutting edge
- KC7325™ grade contains a double coating for broad-band applications, and a TiN top layer serves as a wear indicator for easier monitoring of small drills, which can be difficult to see
