RUKO Hss 9 Step 6-30.5 Mm 101098

RUKO HSS 9 Step Drill Bit 6-30.5 mm | Precision Metal DrillingElevate your drilling capabilities with the RUKO HSS 9 Step Drill Bit, the ultimate accessory for professionals and craftsmen demanding precision, efficiency, and versatility. Designed as an individual, high-performance solution, this single bit replaces a full set of 9 conventional drill bits, allowing you to seamlessly drill multiple hole sizes from 6 mm to 30.5 mm without ever changing the tool. It is expertly engineered for drilling into various materials, especially metal sheets, offering unparalleled performance for electricians, plumbers, automotive technicians, and metal fabricators.Experience a new standard in drilling excellence. This step drill bit is not just a tool, but a guarantee of clean, burr-free holes with every use. Its advanced design ensures a smooth and stable drilling process from start to finish. The precision-engineered point cut (Shape C: Split point) allows for effortless self-centering, eliminating the need for a center punch and preventing the bit from walking on the material surface. This ensures perfect hole placement every time. Furthermore, the robust 10.0 mm shank features a 3-way clamping surface, providing a secure, slip-free grip in your drill´s chuck for maximum torque transfer and operational safety.Superior Performance with Advanced Flute TechnologyThe core of this bit´s exceptional capability lies in its state-of-the-art construction. The CBN ground and spiral flutes guarantee quiet running and high cutting performance. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. The cone makes it easier to withdraw the tool from the material, enhancing workflow efficiency and reducing user fatigue. This meticulous design translates to faster cutting speeds, longer tool life, and a superior finish on the workpiece, saving you time and money.Specifications:- Ø: 6.0 - 30.5 mm- Total length L1: 80.0 mm- Shank Ø: 10.0 mm- Size no: 8- Steps: 9- Material: HSS- Surface: Bright- Cutting direction: Right hand cut- Shank: 3-way clamping surface- Point angle: 118°- Point cut: Shape C: Split point- Step angle: 90°- Tolerance: work´s specification- Weight: 0.12500 KG
