Punta elicoidale RUKO SPB-TL3000 9,0 mm DIN338 HSS-G

Precision ground from high-speed steel to DIN 338, this 9.0 mm twist drill bit delivers clean, accurate holes in steel up to 900 N/mm² tensile strength. The bright, uncoated surface reduces friction and heat build-up, while the 118° point angle and right-hand cutting geometry ensure fast chip evacuation and long tool life.

Overview

The RUKO SPB-TL3000 is a professional-grade twist drill bit engineered for reliable performance in a wide range of materials. Its cylindrical shank fits standard drill chucks, and the h8 tolerance guarantees consistent diameter for precise holes. The standard helix flute design provides excellent rigidity and efficient swarf removal, making it suitable for both hand-held and stationary drilling machines.
