Create higher quality U drills
Imported materials + double spiral holes
Technology + surface coating

Producible diameter size
According to customer needs

Using an asymmetrical u drill  to enter a workpiece creates an imbalance.

Step technology provides a progressive cut with lower cutting forces, resulting in higher productivity and tight hole tolerances.
* Wiper geometry for optimal surface finish or higher feed possibilities
*Optimized chip channel accelerates chip evacuation
*Easy identification by laser marking drill bit, blade and screw codes on the drill shank
Two or four cutting edges depending on drill diameter
*Optimized geometry ensures high performance for most materials
*Optimized material ensures longer blade life
