ADVANTAGES
• Helical HSS bit Made from high quality super fast steel DIN 338, roll laminated, right cutting, Type N, Cylindrical shank.
• Sharppened bit tip with a 118° attack angle, to improve the drilling quality on soft materials.
• Tensile strength < 900 N/mm².
• Double spiral groove for an optimal debris extraction.
• High elasticity to reduce small diameter bits breaking.
• Black oxide coating to improve the cutting quality while increasing the bit s heat resistance.
APPLICATIONS
Specially suited to drill cast iron and steels with a hardness level up to 900 N/mm2, non ferrous metals
like aluminum, copper, brass, hard plastics and soft alloys.
USE
Use with a hand drill, bench drills with a 10 mm or more chuck.
