Drills for high speed drilling of stainless steels and exotics

To complement its successful range of universal high performance carbide drills, Guhring has launched a new range of drills for stainless steels, nimonics, Inconel, titanium and titanium alloys (RT100VA).

The RT100VA range covers four variants: 3xd plain shank, type HA; 3xd whistle notch shank, type HE; 5xd plain shank, type HA; and 5xd whistle notch shank, type HE.

The RT100VA range is produced from a new grade of Guhring carbide, has completely optimised geometry and a features new wear-resistant coating, TiAlN NanoA.

The results are a very strong rigid drill able to perform at elevated feed rates that allows for the maximum volume of internal coolant supply thereby allowing excellent heat dissipation via the chips and, in addition counteracting the possibility of work hardening.
