Bosch HSS-G Metal Drill Bits, Long Series, 4.5mm (Pack of 5)
Precision-ground Bosch HSS-G drill bits (4.5mm) for fast, accurate metal drilling. Self-centring tip, no pilot needed. Pack of 5.
The Bosch HSS-G Metal Drill Bits are precision-engineered for drilling through metal with exceptional accuracy and efficiency. Made from high-speed steel (HSS), these bits offer superior durability and performance, ideal for both alloyed and non-alloyed metals, cast iron, and hard plastics.
Key features include a 135-degree self-centering split-point tip, which ensures active cutting and perfect centring without wandering. This eliminates the need for pre-punching or pilot drilling up to 10mm diameters, saving you time and effort. The precision-ground HSS construction allows for up to 40% faster drilling speeds and 50% lower feed pressure compared to standard HSS bits, making your work quicker and easier.
Designed for use in drill stands and drill drivers, these bits have a cylindrical shank system (shank diameter equals drill bit diameter) and comply with DIN 338 standards. The Type N flute angle and h8 diameter tolerance ensure consistent and reliable performance.
