Description

TRUXON^® Nano-Coated Cobalt Step Drills

TRUXON^® nACo^® Coated Cobalt Step Drills are designed for professionals who need fast, accurate hole drilling in tough metals. Available in 4-20mm and 4-30mm ranges, these heavy-duty step drills cut cleanly through mild steel, hardened steel, stainless steel, cast iron, and titanium, ideal for electrical, fabrication, automotive, and workshop use.

Made from premium M35 cobalt steel, they deliver superior hardness and long-lasting edge retention, even under high heat and continuous use. The advanced nACo^® blue coating reduces friction, increases cutting speed, and provides excellent heat and wear resistance, extending tool life on demanding jobs. A two-flute spiral design improves chip control, reduces binding, and produces smoother, more controlled cuts, while laser-etched size markings remain easy to read for quick, accurate hole sizing without guesswork.

Backed by TRUXON^® Premium Tools Satisfaction Guarantee.
