ريشة حفر HSS M2 ثلاثية المجاري 6 مم

The Ronix RH-5769 M2 HSS Three-Flute Drill Bit 6 mm is designed for precision hole drilling with a 6 mm size, 57 mm working length, and 113 mm overall length. Made from M2 material with a titanium surface finish and 63–65 HRC hardness, this drill bit has a 3-flute cutting design that helps increase chip removal rate and reduce drilling time. The reduced thermal and mechanical stresses on the cutting part help increase the drill bit’s lifespan, while the 124° point angle, right-hand spiral, and three cutting edges support precision drilling performance.
