Bosch HSS-Co Metal Twist Drill Bit 7mm - Pack of 10

Summary

The Bosch 7 mm HSS-Co Metal Twist Drill Bit is a cobalt-alloyed, fully ground jobber-length drill bit designed for fast, precise drilling in tough and hard metals. Supplied in a pack of 10, it is aimed at trades professionals in construction, engineering, and metalwork who demand consistent performance and extended bit life. The cobalt content delivers superior heat and wear resistance compared to standard HSS bits.

Features

• Manufactured from alloyed high-speed steel with 5% cobalt content (HSS-Co) for outstanding heat and wear resistance.
• Conforms to DIN 338 Type N (standard flute angle) with diameter tolerance h8 for consistent, accurate hole sizing.
• 135-degree self-centring split-point tip provides precise starting without wandering, eliminating the need to centre-punch.
• Split-point geometry removes the requirement to pilot-drill holes up to 10 mm diameter.
• Enables up to 40% faster drilling rates and up to 50% lower feed pressure compared with standard HSS drill bits.
• Two-flute design with two cutters efficiently removes chips and reduces heat build-up during use.
• Suitable for drilling alloyed and non-alloyed steels, stainless steel, cast iron, and other hard metals.
• Compatible with pillar drills, drill stands, and standard rotary drills and drivers with a keyed or keyless chuck.
