Ruko Hss 9 Step Drill Bit 4-20 Mm. RUKO HSS 9 Step Drill Bit 4-20 mm | Precision Metal DrillingElevate your drilling capabilities with the RUKO HSS 9 Step Drill Bit, a masterclass in efficiency and precision for all your metalworking projects. As a leading product in electric tool accessories, this individual 20 mm step drill bit is engineered for professionals and craftsmen who demand superior performance and flawless results. It is the ultimate tool for drilling clean, perfectly round holes in a variety of metals, replacing a full set of conventional drill bits and streamlining your workflow.Key Benefits & Superior PerformanceThis versatile HSS step drill bit allows you to create 9 different hole sizes, ranging from 4 mm to 20 mm, with a single, robust tool. This eliminates the constant need to switch bits, saving you valuable time on the job and reducing the weight of your toolkit. Its design is optimized for drilling into sheet metals, stainless steel, non-ferrous metals, and plastic panels, delivering burr-free holes without deforming the material. The Shape C split point at the tip ensures immediate self-centering, preventing the bit from wandering and eliminating the need for a preliminary pilot hole. The secure 3-way clamping surface on the shank guarantees a non-slip grip in your drill chuck, providing maximum torque transfer and enhanced safety during operation.The core of its exceptional performance lies in its advanced geometry. 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, ensuring a smooth and snag-free process from start to finish. This meticulous engineering not only boosts cutting speed but also significantly extends the service life of the drill bit.Attributes:* Max Diameter: 20 mm* Type: Individual* Primary Material: MetalSpecifications:* Diameter Range (Ø): 4.0 - 20.0 mm* Total Length (L1): 75.0 mm* Shank Diameter (Ø): 8.0 mm* Size Number: 1* Number of Steps: 9* Material: HSS (High-Speed Steel)* Surface: Bright* Cutting Direction: Right Hand Cut* Shank: 3-way clamping surface* Point Angle: 118°* Point Cut: Shape C Split Point* Step Angle: 90°. tradeinn Bricoinn
