Bosch HSS-G Metal Twist Drill Bit 8 x 117 mm

This single-piece Bosch HSS-G twist drill bit is designed for metalworking. Made from ground high-speed steel, it is intended for drilling holes in a range of industrial and workshop materials. Its composition allows it to penetrate alloyed and unalloyed steel, as well as cast steel and iron powder ceramics. It is also rated for grey and malleable cast iron, covering a wide range of fabrication work. The bit can be used on non-ferrous metals and hard plastics.

It fits directly into compatible handheld or stationary drills. The bright finish makes it easy to spot in a cluttered toolbox or storage organiser. Weighing 37 g, it adds minimal bulk to the chuck while remaining rigid during high-friction work. The shank seats securely in the drill jaws to maintain rotational balance. The design ensures consistent performance across the supported materials.

• 8 mm drill bit diameter provides accurate sizing for hardware clearance and fastening.
• 117 mm total length offers sufficient reach for recessed or deeper drilling areas.
• 75 mm working length ensures sustained cutting through thicker material cross-sections.
• 135° point angle starts cuts cleanly and minimises wandering on smooth metal surfaces.
• Two distinct cutting edges facilitate efficient chip clearance to prevent binding during operation.
• 8 mm cylindrical shank ensures direct compatibility with standard drill chucks without adapters.
