Back To Top
    • GOdrill 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.
