Features and benefits

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.

Create Solution to calculate Feeds and Speeds

After creating a solution just choose the Feeds & Speeds icon and our system will provide recommendations. You can customize the information by adding your machine and specifications or make adjustments using the sliders.
