HSS-STANDARD SERIES ANNULAR CUTTERS
THE STANDARD BESTSELLER CORE DRILLS
HSS-Standard annular cutters are reliable core drills for metal manufactured from premium M2 high-speed steel. These fully ground annular cutters deliver precise drilling, clean burr-free holes, and fast material removal. Ideal for steel, structural metal, and general fabrication using magnetic drilling machines in workshops and industrial environments.
Designed in Germany, HSS-Standard annular cutters for metal drilling provide excellent durability, high heat resistance, and consistent hole accuracy. Optimized cutting geometry reduces cutting forces and improves chip evacuation. Perfect for everyday professional drilling in steel construction, metalworking shops, and industrial maintenance with magnetic drilling machines.
