Product Description
Bosch 2608585893 HSS-Co Cobalt Drill Bits set features 10 precision-engineered drill bits made from alloyed high-speed steel containing 5% cobalt. This composition provides exceptional heat and wear resistance, making these drill bits suited for tough and hard steel materials. Each drill bit is manufactured to the DIN 338 standard with a cylindrical 7.5mm shank and 3 helical flutes.
The drill bits have a 135-degree self-centring split-point tip that ensures accurate positioning and prevents wandering during drilling operations. This feature also eliminates the need for pilot holes or pre-punching when drilling holes up to 10mm diameter, improving operational efficiency.
The spiral helix flute design facilitates rapid removal of swarf and debris to maintain smooth drilling progress. These cobalt drill bits outperform standard HSS bits delivering up to 40% faster drilling rates and requiring 50% less feed pressure. They are suitable for drilling alloyed and non-alloyed steel materials with tensile strength up to 1000 N/mm².
Compliant with DIN 338/1414 standards, this set is ideal for industrial, construction, engineering, and metalworking applications. They can be used with pillar drills, drill stands, or hand drills.
High-speed steel with 5% cobalt for enhanced durability. 135° split-point tip for precision and no walking. Helical flutes for efficient chip removal. Suitable for hard steel up to tensile strength of 1000 N/mm². Compatible with manual and machine drilling operations.
The package contains 10 drill bits with an overall length of 109mm and a drilling length of 69mm each. The shank size is 7.5mm cylindrical type with a right-hand cutting direction. These drill bits are manufactured in China, ensuring reliable industrial quality and performance.
Bosch drill bits deliver superior drilling accuracy, prolonged tool life, and higher productivity.
