Bosch High-Speed Steel Cobalt Drill Bit Set, 10 Pieces, 75mm Overall Length, 4.2mm Shank Size, 135° Point Angle 2608585882

Bosch 2608585882 high-speed steel cobalt drill bit set consists of 10 pieces of premium HSS-Co drill bits with an overall length of 75mm, designed for demanding industrial, construction, and engineering applications. Manufactured to DIN 338 standards, these drill bits are alloyed with 5% cobalt content to provide superior heat resistance and durability when working on tough, hardened steels and other hard materials.

The set features cylindrical shanks of 4.2mm diameter compatible with standard chucks, and each drill bit is precision ground with 3 helical flutes to enable rapid removal of debris and efficient cutting. The 135-degree split-point tip design delivers excellent positional accuracy with self-centering capability, eliminating the need for pre-punching or pilot holes up to 10mm diameter.

These drill bits can be reliably used for drilling in various materials including alloyed and non-alloyed steel with tensile strength up to 1000 N/mm², as well as plastics, wood, and metal. The right-hand cutting direction combined with a 43mm drilling length ensures efficient penetration and clean holes.

This Bosch drill bit set is suited for both hand-held use and machine tools such as pillar drills and drill stands. The cobalt alloy contributes to up to 40% faster drilling rates and 50% lower feed pressures compared to standard HSS bits, enhancing productivity in mechanical, fabrication, and maintenance tasks.

Constructed from heat-resistant HSS-Co with 5% cobalt alloy. Precision-ground helical flutes optimize cutting and swarf evacuation. 135° split-point tip prevents wandering and improves accuracy. Compliant with German DIN 338/1414 industry standards.

Suitable for a wide range of materials including steel, wood, and plastics. Configured with a 4.2mm cylindrical shank for secure holding. Facilitates faster drilling speeds with less feed pressure. Versatile for hand and machine use in industrial and workshop environments.

Set contains 10 pieces, making it comprehensive for multi-size drilling needs. Manufactured in China under Bosch standard quality controls. Explore the extensive range of Bosch Drill Bits at EnvMart for quality performance in industrial, laboratory, construction, and manufacturing settings.
