ADVANTAGES
• Helical HSS-Co made from high quality super fast steel alloyed with 5% Cobalt , DIN 338, rectified, right cutting, Type N, Cylindrical shank.
• Sharppened bit tip with a 135° attack angle, improved drilling on hard materials increasing the drilling speed over beveled edge bits. Sharpened in accordance to DIN 1412 C.
• Split Point to avoid bit sliding while improving drilling quality.
• Milled bit for an optimal precission.
• Tensile strength < 1200 N/mm².
• Double spiral groove for an optimal debris extraction.
• Long lifespan: Cobalt alloy significantly improves heat and wear resistances.
APPLICATIONS
Specially suited for stainless steel drilling, alloyed and non alloyed steels with a tensile strength up to 1200 N/mm², grey casting and steel casting.
USE
Use with a bench drill, not sutiable for hand drills due to the bits hardness.
