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.
- For the machine tap/material assignments, see the overview tables
