Bosch Professional HSS-Co Metal Drill Bit 2.5 x 30 x 57mm DIN 338

Summary

The Bosch Professional HSS-Co Drill Bit is a cobalt-alloy, fully ground high-speed steel twist drill bit designed for demanding metal-drilling applications, including stainless steel and heat-resistant alloys. Manufactured to DIN 338 standard, it offers exceptional wear and heat resistance, making it the go-to choice for trade professionals working with hard or tough materials. Its split-point tip ensures accurate, self-centring entry without the need for a centre punch.

Features

• Manufactured from cobalt alloy and fully ground HSS, providing superior heat and wear resistance compared to standard HSS bits.
• Contains 5% cobalt content, accounting for its robust performance in demanding drilling conditions.
• 135-degree split-point tip delivers active cutting and precise self-centring without wandering.
• Two cutters and two flutes efficiently remove chips, extending bit life during continuous use.
• Type N flute angle geometry, optimised for metal drilling applications.
• Diameter tolerance of h8 ensures accuracy and consistency in hole size.
• Cylindrical shank (shank diameter equals drill bit diameter), compatible with drill stands and drill drivers.
• Suitable for alloyed and non-alloyed steel (up to 1000 N/mm2 tensile strength), stainless steel V2A/V4A, cast iron, cast steel, and acid/heat-resistant steels.
• Manufactured to DIN 338 standard for reliable, repeatable performance.
