Product Features

1.A little longer is better!

A semi-long shape allows for more efficient external lubrication and achieves excellent machining results.

2.lmproved torque reduction!

The combination of a unique thread relief and a coating that maximizes the benefits of surface treatments results in reduced torque and improved welding-resistance.

3.Optimized flute shape!

A slightly wider flute means a higher volume of lubricant can be applied, resulting in improved lubricity and cooling abilities.

4.Optimized for medium-hard steels!

Adopting a tool material suitable for the work materials in combination with a special coating means EHRZ is suitable for medium-hard steels up to 40HRC as well as stainless steels.
