Bosch HSS-Co Metal Drill Bits 8mm DIN 338 - Pack of 5

Summary

The Bosch HSS-Co 8mm Twist Drill Bit is a high-performance cobalt-alloy metal drill bit designed for demanding metalworking applications. Manufactured to DIN 338 standard, it is suited to trade and professional use in engineering, construction, and fabrication. Supplied in a pack of five, it offers excellent value for repetitive or heavy-duty drilling tasks.

Features

• Manufactured from fully ground high-speed steel with 5% cobalt content, providing superior heat resistance and wear durability compared to standard HSS bits.
• Suitable for drilling alloyed and non-alloyed steel, stainless steel (V2A/V4A), cast steel, cast iron, and acid- and heat-resistant steels.
• 135-degree self-centring split-point tip delivers active cutting and precise centring without wandering, eliminating the need for centre-punching up to 10mm.
• Type N flute geometry to DIN 338 with diameter tolerance h8 ensures consistent, accurate hole sizing.
• Dual cutters and dual flutes rapidly evacuate swarf for cleaner holes and extended bit life.
• Cylindrical shank (shank diameter equal to drill diameter) is compatible with standard three-jaw drill chucks.
• Suitable for use with pillar drills, drill stands, and handheld drill drivers; not compatible with SDS chucks.
• Use of universal cutting oil is recommended to maximise service life when drilling tough steels.
