Product Description

*For use in alloyed and unalloyed steels up to 900 N/mm2 tensile strength, sheet metal and thin-walled profile material(pipes and without pre-punching), where exact and clean drilling is required.

* For use with impact drivers.

*Special designed pilot point penetrates material faster and allows precise drilling on curved surfaces.

* Optimized flute geometry specially ground shoulder cutting flutes for milling exact circular holes with clean edges.

* Titanium coating for increased wear resistance, corrosion resistance and up to 2x life(vs black oxide).

* Core reinforcement 2x longer life, 2x stronger core. Constantly increasing core diameter in the direction of the shaft for increased durability. Gives maximum fracture stability.

* Quick change shank DIN6.35E for rapid change of accessory.



*Other special sizes are also available on the customers' special request.
