HSS-R twist drill
The powerful HSS-R twist drills are suitable for all normal drilling operations in most commonly used materials. Due to the rool-forged production process, the material is solidified and provides an increased breakage resistance.
The drills are suitable for alloyed and unalloyed cast steel up to 900 N/mm², steel, grey cast iron, malleable iron, spheroidal graphite iron and pressure die-casting, sinter iron, nickel silver, graphite, short-chipping aluminium alloys, brass and bronze.
