RUKO SPB-DIN338 broca helicoidal HSS-G rectificada 10,8 mm punta en cruz

Twist drill bit with 10.8 mm diameter, fully ground from high-speed steel (HSS-G) to DIN 338. The split point tip with 135° point angle centres precisely on contact and reduces walking, while the bright finish and standard helix angle support efficient chip evacuation in metal, plastic, and wood.

Advantages

Self-centring split point for accurate hole positioning. Fully ground flutes and tapered core provide stability and smooth cutting. HSS-G material offers good heat resistance and long tool life in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics.
