||Drill for counter boring has great performance.
Aqua EX Coating
- Spot facing machining capability for a wide range of applications such as spot facing on slope, correction of eccentric holes, and thin plate machining.
Drilling efficiency improvement due to reduced processing time
- Better heat and wear resistance from Aqua EX coating for a super long life.
- Counter boring and guide hole drilled at the same time.
- Effective screw length is assured when drilling set screw holes in thin material, without increasing work.
