Bosch HSS-G Drill Bit - 4.3mm, Pack of 10

Introducing the Bosch 4.3mm High-Speed Steel (HSS) Ground Drill Bit, available in a pack of 10. Engineered for precise metal drilling, these drill bits showcase an innovative 135-degree self-centering split-point tip that guarantees spot-on centring and active cutting without any wandering. The result? Unfailing precision every time. What's more, the split-point feature completely eliminates the necessity of pre-punching or pilot drilling up to a diameter of 10mm. It's all about saving time without compromising on performance. Crafted from high-speed steel (HSS), these precision-ground drill bits are designed to work wonders. Boasting up to 40% enhanced drilling speed and 50% lesser feed pressure, they outclass ordinary HSS drill bits with chisel edges. Versatility is another prime feature. Whether it's alloyed or non-alloyed steel, cast steel or iron, sintered iron or malleable cast iron, or even hard plastics and non-ferrous metals, these Bosch drill bits can efficiently create holes in a wide array of materials. Constructed in compliance with DIN 338 standards, the Bosch HSS drill bits sport a Type N flute angle with a diameter tolerance of h8. Fit them snugly into their cylindrical shank system – designed to mirror the drill bit diameter – and they’re all set to be used in drill stands and drill drivers.
