Description

Description:

This shape is also called the "Takenoko Drill". The spiral groove on the 2-blade has a chip breaker function that reduces the amount of grains that occur during use, and reduces the amount of heat generated to extend the life of the blade for speedy drilling work and cutting edge. The tip is thinned for a very good bite. If you have not had a lot of drills or hole saws, you can expand the holes gradually.
