Bosch High-Speed Steel Cobalt Drill Bit Set 65mm Length 3-Flute Helical Shank 3.3mm 10 Pieces 2608585878

Bosch 2608585878 high-speed steel cobalt (HSS-Co) drill bit set is engineered for superior performance and durability in drilling applications involving tough and hard steels. This set contains 10 pieces, each with an overall length of 65mm and a drilling length of 36mm, making it suitable for precision and efficient drilling tasks.

Featuring 3 helical flutes and a cylindrical shank measuring 3.3mm, these drill bits are designed for use with standard drill chucks and are not compatible with SDS drills. The 135° self-centring split-point tip ensures excellent positional accuracy and eliminates the need for pre-punching or pilot drilling up to 10mm diameter holes. The high-speed steel alloyed with 5% cobalt offers enhanced heat resistance, enabling faster drilling rates by up to 40% and reducing feed pressure by 50% compared to conventional HSS bits.

Manufactured to comply with DIN 338/1414 standards, the bits deliver excellent wear resistance and reliability for industrial and workshop use. Their right-hand cutting direction aids in rapid swarf removal, improving drilling efficiency and hole quality.

This drill bit set is well-suited for applications in metalworking, construction, engineering, and fabrication where drilling through alloyed and non-alloyed steels up to 1000N/mm² tensile strength is required. The set is also applicable on plastic, wood, and other materials, making it versatile for varied job site conditions.

The pack’s contents enable compatibility with pillar drills and drill stands for added stability during precision drilling operations. The set includes 10 cobalt-enriched HSS drill bits with a 65mm overall length each. Three helical flutes and precision ground split-point tip deliver quick, accurate drilling.

Resistant to heat and wear from high cobalt content alloy composition. Suitable for alloyed steels and materials up to 1000 N/mm² tensile strength. Right-hand cutting direction for optimal chip evacuation during drilling.

Compliant with DIN 338/1414 ensuring consistent high quality and performance. Compatible with pillar drills and drill stands for industrial operations. Manufactured in China adhering to Bosch quality standards.
