RUKO Hss-e Co 5 9 Step 4-12 Mm 101050-9E

RUKO HSS-E Co 5 9 Step Drill Bit 4-12 mm | Precision Metal DrillingExperience unparalleled precision and efficiency in your metalworking with the RUKO HSS-E Co 5 9 Step Drill Bit. Engineered for professionals and discerning craftsmen, this individual drill bit is the ultimate solution for drilling clean, accurate holes in a variety of metal materials. It replaces nine separate drill bits, offering a versatile range from 4 mm to 12 mm in a single, robust tool. Ideal for electrical installations, plumbing, automotive work, and general metal fabrication, this step drill streamlines your workflow, saving you time and space in your toolbox.Designed for superior performance, this step drill excels where others falter. The CBN ground and spiral flutes guarantee quiet running and high cutting performance. This advanced geometry significantly reduces vibration, providing you with a smoother drilling experience and greater control over the tool. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily from the borehole. This exceptional chip evacuation protects the cutting edges from damage and reduces the occurrence of built-up edges and cold weld marks. The result is consistently clean, burr-free holes and a significantly extended tool lifespan, even when working with tough materials. The cone makes it easier to withdraw the tool from the material, preventing snags and ensuring a seamless operation from start to finish.This is more than just a drill bit, it is a high-performance cutting tool designed for accuracy and durability. The split point (Shape C) design ensures immediate, precise centering without the need for a center punch, preventing the bit from walking on the material surface. The 3-way clamping surface on the shank provides a secure, slip-free grip in your drill´s chuck, ensuring maximum torque transfer for efficient cutting power. Whether you are drilling thin sheet metal, profiles, or pipes made of steel, stainless steel, or non-ferrous metals, this 12 mm step drill delivers professional-grade results every time.Specifications:* Drilling Range (Ø): 4.0 - 12.0 mm* Total Length (L1): 65.0 mm* Shank Diameter (Ø): 6.0 mm* Size Number: 0/9* Number of Steps: 9* Material: HSSE-Co 5* Surface: Bright* Cutting Direction: Right-hand cut* Shank: 3-way clamping surface* Point Angle: 118°* Point Cut: Shape C: Split point* Step Angle: 90°
