RUKO SPB-DIN338-HSS-TiAlN kierrepora 12,0 mm

The RUKO SPB-DIN338-HSS-TiAlN twist drill bit stands out with its titanium aluminum nitride coating, which reduces friction and heat buildup for faster drilling and longer tool life compared to uncoated HSS bits. Ground from solid high-speed steel to DIN 338 tolerances, it delivers precise holes in demanding materials.

Highlights

• TiAlN coating for high wear resistance and heat protection
• Ground from solid HSS for accuracy and durability
• 130° point angle optimised for metal drilling
• Right-hand cutting, cylindrical shank, diameter 12.0 mm

In daily use

This bit is suited for steel, stainless steel, cast iron, and non-ferrous metals. The TiAlN coating allows higher cutting speeds and feeds, while the h8 shank tolerance ensures a secure grip in standard drill chucks. The 101 mm working length provides good reach for most workshop tasks.
