○ Suitable for drilling small diameter holes less than 3mm. It is possible to operate stably due to aqua coating and new geometric. Tipping resistance.wear resistance of corner edge is increase
○ By Aqua Coating (PAT.P). which is wealthy in the lubrication with the work material and excellent to heat-resistance.
