SMART365 HSS-Co Step-Tec kierreporat 5,0 mm, 10 kpl:n pakkaus

The SMART365 HSS-Co Step-Tec twist drill bit set offers precision and durability for demanding metal drilling applications. Manufactured from high-speed steel with 5% cobalt content, these bits provide excellent heat resistance and extended tool life when working with stainless steel, alloyed steel, cast iron, and non-ferrous metals. The 135° split point ensures self-centering and reduces walking, while the fully ground cylindrical shank guarantees concentricity and secure chuck grip. Each bit conforms to DIN 338 standard with h8 tolerance for consistent hole quality. This 10-piece set includes bits with a 5.0 mm diameter, ideal for professional workshops and industrial maintenance tasks.

Advantages

Enhanced durability and heat resistance thanks to cobalt alloy; self-centering split point eliminates the need for pilot holes; precise h8 tolerance ensures accurate drilling; bright/bronze surface finish reduces friction and chip buildup; suitable for both corded and cordless drills as well as drill presses.
