RUKO SPB-DIN338 punta elicoidale HSS-G 6,75 mm affilatura a croce

The RUKO SPB-DIN338 HSS-G Kreuz 6.75 mm is a precision twist drill bit ground from solid high-speed steel, featuring a cross-ground split point for immediate self-centering without a centre punch.

• Cross-ground split point: self-centering, no walking
• 135° point angle reduces thrust and improves hole quality
• DIN 338 standard with h8 shank tolerance for precise chuck fit
