For work in an extensive range of materials
The universal geometry allows processing of many different materials.
Long service life and good process reliability
The X allowance ensures an increased service life and process reliability.
Very good adhesion of coolants and lubricants as well as reduced tendency for build-up of materials
The vaporised surface enables coolants and lubricants to stick well and reduces the tendency for deposits to build up.
Sufficient coolant and lubricant must be added when cutting threads.
Datasheets(X)
Before reversing the screw tap, the entire spiral point of the tool must be removed from the drill hole. Failure to do so may cause cutting edges to chip or the tool to break.
