RUKO HSSE Co 5 Spiral Fluted Step Drill Bit with Split Point, Bright Finish, 4.0 20.0 mm Diameter, Size 1, 75.0 Length, R101051E

Ruko Hss-e Co 5 9 Step Drill Bit 4-20 Mm. RUKO HSS-E Co 5 Step Drill Bit 4-20 mm | Professional High-Performance Metal DrillingElevate your metalworking projects with the RUKO HSS-E Co 5 9 Step Drill Bit, the definitive solution for professionals demanding precision, efficiency, and durability. Designed as a superior accessory for your electric tools, this individual step drill bit masters the challenge of drilling multiple hole sizes from 4 to 20 mm in a single, seamless operation. It is expertly engineered for high-performance applications in metal, including tough materials like alloyed and non-alloyed steel, stainless steel sheets, and non-ferrous metals. Say goodbye to carrying multiple drill bits and hello to the streamlined power of one versatile tool.Unmatched Performance and Quiet OperationExperience a new standard in cutting performance. The CBN ground and spiral flutes guarantee exceptionally quiet running and high cutting performance, allowing for smooth and controlled drilling every time. A key innovation of this design is the optimized chip flow. This advanced feature ensures that even long, non-breaking chips, often a problem in metal drilling, are removed easily and efficiently from the workpiece. This superior chip evacuation protects the delicate cutting edges from damage, significantly reduces the formation of built-up edges, and prevents cold weld marks on your material. Furthermore, the integrated cone design makes it easier to withdraw the tool from the material, saving you time and preventing damage to the freshly drilled hole.Engineered for Durability and PrecisionThis 20 mm step drill is crafted for professionals who cannot compromise on quality. The robust construction ensures a long service life even under demanding conditions, making it a reliable partner for electricians, plumbers, HVAC technicians, and industrial maintenance crews. The split point (Shape C) design provides an immediate, precise start without the need for center punching or a pilot hole, preventing the bit from walking on the material surface. Each of the 9 steps is clearly defined, allowing you to drill clean, burr-free holes to the exact diameter required. The 3-way clamping surface on the shank ensures a secure, non-slip grip in your drill´s chuck, delivering maximum torque transfer and enhancing operational safety. For any project requiring clean, accurate holes in metal, this individual step drill bit is the ultimate choice.Specifications:* Diameter Range (Ø): 4.0 - 20.0 mm* Total Length (L1): 75.0 mm* Shank Diameter (Ø): 8.0 mm* Size No.: 1* 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°* Tolerance: work´s specification* Weight: 0.06000 KG. tradeinn Bricoinn
