Bosch PointTeQ High-Speed Steel Twist Drill Bit 4.5 mm Cylindrical Shank 1 piece

This 1-piece Bosch PointTeQ HSS twist drill bit is designed for metalworking applications. Made from high-speed steel, it withstands the friction of continuous drilling into tough industrial materials without blunting. It is rated for use on both standard steel and solid cast iron, and its hardened composition supports consistent chip removal when boring through dense stock. It serves as a direct replacement or a size addition for existing workshop toolkits.

The PointTeQ tip design helps the bit centre on contact, reducing wandering across smooth workpieces. Because it establishes a secure starting position, a centre punch is not usually required. The bit is built to operate with standard right-hand rotation and is intended for use with a conventional rotary drill or drill driver, ensuring predictable performance in a standard powered setup.

• 4.5 mm cutting diameter for precise hole creation to match specific fasteners and pilot requirements.
• 47 mm working length, defining the maximum depth of material the bit can penetrate in a single pass.
• 80 mm overall length, balancing reach and rigidity under rotational load.
• Cylindrical shank that fits standard three-jaw drill chucks without the need for specialised adapters.
• 4.5 mm shank diameter, matching the cutting width for uniform torque transfer from the chuck jaws.
