FEIN HM-Ultra 35 QuickIN kernboor 17 mm 63127091016

Precision core drilling in tough steels demands a cutter that stays sharp, runs true, and lasts through repeated jobs. The FEIN HM-Ultra 35 QuickIN annular cutter with 17 mm cutting diameter and 35 mm cutting depth is engineered for exactly that: clean, fast holes in steel, stainless steel, non-ferrous metals, and cast iron without the chatter or wander of twist drills.

Who is it for

Professional metalworkers, fabricators, and maintenance crews who need accurate, large-diameter holes in plate, pipe, or structural sections. It fits FEIN magnetic core drills with QuickIN mount, making bit changes tool-free and secure.

Tips

Always use cutting fluid or a coolant system to maximize cutter life and hole quality. For stainless steel, reduce speed and apply steady pressure to prevent work hardening. Keep the cutter's interior free of chips and inspect the carbide tips regularly for wear. Store in a dry place to avoid corrosion.
