Drill for counter boring has great performance. Spot facing machining capability for a wide range of applications such as spot facing on slope, correction of eccentric holes, and thin plate machining. Aqua EX Coating Better heat and wear resistance from Aqua EX coating for a super long life. Drilling efficiency improvement due to reduced processing time 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.
