EX-SUS-GOLD Drills (1600)

Drills Designed for Stainless Steel


The Ex-SUS-Gold drill line is famous worldwide for its incredible performace gummy materials, like stainless steel. Its high helix and refine X-thinning point geometry yield incredible sharpness, which make it the ideal solution for processing soft materials. Available in stub and jobber lengths and in diameter increments of every 0.0004" (0.01mm).


X-Thining Point Geometry

No center drills neeeded. Achieves high accuracy high shearing forces ideal in gummy materials.

HSS-Vanadium Substrate

Added heat resistance via 3% Vanadium content yields superior performance to standard High Speed Steel drills.

Titanium Nitride Coating

Increased hardness and lubricitiy inceases wear resistance thereby extending tool life.

As small as 0.5mm in diameter increments every 0.01mm (0.0004").

Over 3,500 sizes available from stock, with diameter tolerances that can replace reaming operations
