Ruko Hss N22 Ø 5-22.5 Mm Conical Drill Bit. RUKO HSS N22 Conical Drill Bit Ø 5-22.5 mm | Precision Step Drill for MetalAchieve flawless, burr-free holes in sheet metal with the professional-grade RUKO HSS N22 Conical Drill Bit. As a premier accessory for your electric tools, this individual step drill is engineered to deliver unparalleled precision and efficiency, replacing an entire set of conventional drill bits. It is the ultimate solution for drilling and enlarging holes in a variety of metal materials, offering a seamless drilling range from 5.0 mm to 22.5 mm in precise 2.5 mm increments with a single tool.Designed for professionals who demand perfection, this conical drill bit stands out for its superior cutting quality. The CBN ground flutes guarantee quiet running and high cutting performance. This advanced grinding method produces exceptionally sharp cutting edges that create clean, perfectly round holes without burrs on either side of the workpiece, saving you critical time by eliminating the need for post-drilling deburring. The optimized flute geometry ensures smooth chip removal for consistent and efficient operation.Ease of use is at the core of its design. The Shape C split point tip allows the bit to self-center, making it incredibly easy to start a hole precisely where you want it without the need for a preliminary center punch. This prevents the bit from walking across the material surface, ensuring accuracy from the very first rotation. Once your drilling is complete, the unique cone makes it easier to withdraw the tool from the material, preventing snags and protecting your workpiece from damage.For maximum power transfer and safety, the drill bit features a 3-way clamping surface on its shank. This innovative design prevents the bit from slipping in the drill chuck, even under high torque, ensuring that all the power from your drill is delivered directly to the cutting edge for optimal performance in demanding metal drilling tasks. Crafted from high-speed steel (HSS), this durable and reliable conical drill bit is built for a long service life in industrial and workshop environments.Specifications:- Drilling range Ø1-Ø2: 5.0 - 22.5 mm- Total length L1: 79.0 mm- Shank Ø: 8.0 mm- Size no.: 9- Material: HSS- Surface: bright- Cutting direction: right hand cut- Shank: 3-way clamping surface- Point cut: Shape C: Split point- Point angle: 118°- Point cut: work´s specification- Cone angle: 20-30°- Tolerance: work´s specification- Weight: 0.06200 KG. tradeinn Bricoinn
