·　Reduces set up time

·　No more CBN-ground flutes without burrs mean a superior cutting edge an longer tool life.

·　Each step has a radially adjusted relief produced by CBN grinding,relating directly to the diameter of the step, so the cutting edge is always the highest point of the diameter

·　Each step is axially CBN relief-ground, meaning the cutting edge is also the highest point of the axial cutting axis

·　The cutting edge of each step has relief angle,meaning the cutting edge is also the highest point in advance direction
Use Steel drills for :

·　Sheet metal working in electrical, sanitary engineering, heating technologies, automotive, mechanical engineering,switching systems and aviation

·　Non-ferrous metal,steel,stainless steel,thermoplastics, duroplastics ,sheet metals up to 0.16”(8 ga.)thick

·　Center,spot-drill,bore and debur - all in one operation
