Bosch 2608577172 HSS PointTeQ Metal Twist Drill Bit 8.5 x 117 mm

The Bosch 2608577172 HSS PointTeQ Twist Drill Bit 8.5 mm is a single-piece accessory engineered for metalworking. This twist drill bit bores efficiently through alloyed and unalloyed steel, cast iron, and other ferrous materials. It functions primarily as a clearance tool for continuous fabrication tasks. Designed with a self-centering PointTeQ tip, the bit establishes immediate contact with the work surface to minimise wandering. Securing a stable entry point helps maintain accurate alignment throughout the drilling process. Built for standard rotary applications, the bit provides consistent material removal.

Integrating directly into existing tool setups, the accessory relies on a straight shank design fitting conventional chucks. Its geometry allows for secure clamping, which prevents the tool from slipping under heavy load. Silver-finished flutes channel metal swarf away from the cutting zone to keep the bore clear. The bit operates reliably with standard power drills and drill drivers. Because it requires no proprietary holders, it serves as a straightforward replacement in active shop inventory. Operators rely on this High-Speed Steel construction for sustained durability during routine mechanical repairs.

• 8.5 mm cutting diameter provides exact sizing for clearance holes in metal fabrication projects.
• 117 mm overall length offers extended reach to access recessed or layered workpieces.
• 75 mm working length enables continuous deep boring before flute capacity is exhausted.
• 135° point angle improves initial penetration and removes the need for prior centre-punching.
• 8.5 mm cylindrical shank matches the cutter diameter to maintain balanced rotation in standard drill chucks.
