The versatile screw tap for drilling UNC threads for universal use in steels up to a strength of 1,000 N/mm², stainless steels and non-ferrous metals, such as aluminium, aluminium alloys, bronze and plastics.

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.

Notice

Sufficient coolant and lubricant must be added when cutting threads.
