ADVANTAGES
• Helical HSS bit Made from high quality super fast steel 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 < 1000 N/mm².
• Double spiral groove for an optimal debris extraction.
• 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 1000 N/mm2, non ferrous metals like aluminum, copper, brass, hard plastics and medium alloys.
USE
Use with a hand drill, bench drills with a 10 mm or more chuck.
