Bosch HSS-G Twist Metal Drill Bit 6 x 93 mm

The Bosch HSS-G Twist Drill Bit 6 x 93 mm is a single-piece high-speed steel accessory designed for drilling into metal and hard plastics. It is rated for a range of dense materials, including alloyed and unalloyed steel, cast steel, and grey cast iron. The bit also handles sintered iron, malleable cast iron, and various non-ferrous metals. Its ground twist geometry supports clean, accurate hole formation across these applications. This single unit offers a dedicated solution for tasks requiring a specific bore size in standard workshop environments.

A cylindrical shank allows the bit to mount directly into standard keyed or keyless drill chucks. At 6 mm, the shank diameter matches the cutting body, ensuring uniform rotation under load. The tool relies purely on standard rotary action, as the design does not support hammer drilling. Its straight-fluted profile continuously channels swarf up and out of the hole during use. Operating without hammer force prevents unnecessary material fracturing when working with brittle plastics.

• 93 mm overall length provides sufficient reach for standard structural and component work.
• 57 mm working length determines the maximum achievable bore depth in a single pass.
• 135° split-point angle improves centering and removes the need for pre-punching.
• 6 mm cutting diameter creates accurate clearances for matching hardware, fasteners, or tapped threads.
• Two distinct cutting edges support consistent material removal and a uniform bore wall.
• Bright finish results directly from the grinding process applied to the high-speed steel.
