PATIKIL 4.8mm Drill Bit, M42 8% Cobalt High-Speed Steel

NOTE: High cobalt HSS typically has a higher number of drilling times than M2 HSS and M35 HSS under the same conditions, potentially thousands or more. DRILLCO 400N JOBBER LENGTH DRILL BIT SET, BLACK/GOLD, 1/16 TO⅜ IN, 135... The harder the material, the lower the drilling speed should be. A1302 | Dormer A130 Series High Speed Steel Jobber Drill Bit, 50.8mm... 10pcs 0.5mm-13mm Cobalt Drill Bit Set M42 HSS Jobber Metal Twist Drill INSTRUCTION: The twist drill should be at a 90° angle to the workpiece. When drilling different materials, the drilling speed needs to be adjusted. PACKING LIST: 5 packs of drill bits in 4mm(0., 16 inch ≈ 5/32 inch) cutting diameter, 41mm / 1., 61 inch flute length, 72mm / 2., 83 inch overall length, 135-degree split point FEATURE: M42 high-speed steel is formulated with a high 8% cobalt, high hardness and wear resistance, especially suitable for processing hard materials, excellent heat resistance, suitable for high-speed cutting. It is suitable for drilling various materials, including stainless steel, iron, aluminum, copper, plastics, and wood. √APPLICATIONThe M42 8% Cobalt HSS Gold Finish twist drill is engineered for high-hardness, high-viscosity, and high-temperature materials due to its exceptional red hardness, wear resistance, and anti-adhesion properties. It optimally balances high-temperature hardness, wear resistance, and durability. Adjusting the speed can improve cutting efficiency, extend tool life, and reduce material damage. 4mm Drill Bit Set For Hard Metal PATIKIL 4.8mm Drill Bit, M42 8% Cobalt High-Speed Steel Gold Finish Drill Bits For Stainless Steel It is suitable for drilling: High-temperature alloys, Titanium alloys, Stainless steel, Hardened steel, Cast iron, Hard plastics, and Wood√PACKING LIST:-Cutting Edge Diameter: 4mm/0., 16 inch ≈ 5/32inch-Shank Diameter: 4mm-Flute Length: 41mm/1., 61 inch-Total Length: 72mm/2., 83 inch-Package Content: 5pcs x Drill Bit√NOTE:During the machining process, friction between the drill bit and the material generates significant heat. This design improves heat dissipation and tool durability, making it suitable for hardened steel, cast iron, and other tough alloys.
