Bosch HSS-G Extra Length Drill Bit - 9mm, Pack of 5

Revamp your drilling work using our Bosch HSS-G Extra Length Drill Bit. Coming in a pack of 5 and with a 9mm diameter, it has been specifically designed to drill deep holes in metals, both alloyed and non-alloyed, cast steel, cast iron, malleable cast iron, sintered iron, non-ferrous metals, and even hard plastics. This precision-engineered drill bit features a unique 135-degree self-centering split-point tip that provides optimal centering, active cutting, and no wandering, allowing you to work with the utmost precision even while drilling deeply—no need for pre-punching or pilot drilling up to diameters of 10 mm. In addition, the bit's high-speed steel (HSS) composition allows up to a 40% faster drilling rate and reduces the feed pressure by up to 50% in comparison with standard-ground HSS drill bits with chisel edges. Its custom extended length comes tailored to your deeper drilling requirements. Manufactured as per DIN 340 standards, this drill bit boasts a Type N flute angle—giving you the perfect balance of efficiency and durability. With a diameter tolerance of h 8 and a working length of 115 mm and a total length of 175 mm, it affords an unmatched level of control and precision. Also, its cylindrical shank system - with a shank equal to the drill bit diameter - makes it suitable for use in both drill stands and drill drivers. In a nutshell, the Bosch HSS-G Extra Length Drill Bit makes drilling deep holes in varying materials a hassle-free process.
