Brands: EXOPRO^® WHO-Ni Drills

DUROREY Coating

Outstanding performance in high-hardness steels

Lower helix angle

Lower helix angles create stronger cutting faces, essential when cutting Ni-Alloys and hardened steels.

Internal coolant holes

Coolant delivery at the cutting edge reduces heat and improves chip evacuation, thereby increasing tool life and enabling faster drilling speeds.

Nickel Alloys (Inconel, Waspaloy), Heat Resistant Super Alloys, Hardened Steels 40-55HrC

Holes up to 3X diameter in depth, where coolant-through is an option.

Any application where productivity and the lowest cost-per-hole is the goal.
