Bosch High-Speed Steel Cobalt Drill Bit Set, 3-Flute Helical, 80mm Overall Length, 4.5mm Shank, 135° Point Angle 2608585883

Bosch 2608585883 high-speed steel cobalt drill bit set comprises 10 precision-engineered drill bits manufactured from HSS-Co alloy with 5% cobalt content, providing exceptional heat and wear resistance. With a 3-flute helical design and an overall length of 80mm, these bits are designed for high accuracy and extended service life in demanding drilling applications.

The 135-degree self-centring split-point tip reduces wandering for precise hole placement, eliminating the need for pre-punching or pilot holes up to 10 mm diameter. The right-hand cutting direction combined with spiral helix flute geometry enables rapid removal of swarf, ensuring efficient drilling performance.

These bits conform to DIN 338/1414 standards, making them suitable for drilling alloyed and non-alloyed steels up to 1000 N/mm² tensile strength, as well as plastics, wood, and various metals. They are ideal for use with pillar drills, drill stands, and hand or machine tools, making them fundamental tools in mechanical, construction, and engineering industries where speed and precision are critical.

The pack contains 10 drill bits, each with a 4.5mm cylindrical shank and a drilling length of 47mm, providing versatility for multiple applications. Manufactured from alloyed high-speed steel with 5% cobalt for enhanced durability.
