Bosch Professional HSS-Co Metal Drill Bit 4.5mm x 47mm x 80mm

Summary

The Bosch Professional HSS-Co Twist Drill Bit is a single, fully ground cobalt-alloy drill bit designed for demanding metalworking applications, particularly in stainless steel and high-tensile alloys. Manufactured to DIN 338 standards, it is well suited to trade professionals who require consistent, precise results when pre-drilling holes for anchors, rivets, and fixings. Its cobalt-enriched construction delivers superior wear and heat resistance compared to standard HSS bits.

Features

• Manufactured from fully ground high-speed steel with a 5% cobalt alloy content, providing excellent wear resistance and heat protection during extended use.
• Split-point 135deg tip ensures active cutting and precise centring without wandering, reducing the need for a centre punch.
• Two-cutter, two-flute design removes chips efficiently, extending bit life and maintaining hole quality.
• Suitable for drilling alloyed and non-alloyed steel, stainless steel (V2A/V4A), cast steel, cast iron, and acid- and heat-resistant steels.
• Manufactured to DIN 338 with Type N flute angle and a diameter tolerance of h8 for consistent, accurate results.
• Cylindrical shank system (shank diameter equal to drill diameter) compatible with standard drill chucks, drill stands, and drill drivers.
• Recommended for use with cutting oil to maximise bit longevity when working on hard metals.
