Uxcell Reduced Shank Drill Bit Shank High-Speed Steel Twist Hss 9341 - 1/2 Inch / 20.5Mm

Material:-9341 high speed steel, after heat treatment, exhibits excellent hardness, making it suitable for use in high-friction environments.-Drill bits made from high speed steel can effectively resist wear, extending their service life and making them suitable for drilling metals and other hard materials.-9341 Reduced Shank Drill Bit can drill a variety of materials, including stainless steel, carbon steel after heat treatment, iron, aluminum alloy, copper, wood, plastic, etc., with strong adaptability, also including auto repair, modification, appliance installation repairSurface Treatment:-The black nitriding layer formed during the nitriding process effectively resists oxidation and corrosion, making it suitable for use in harsh environments and reducing maintenance frequency, provides lubricity, while the small pore structure effectively retains coolant, enhancing the cooling effect during the cutting process and reducing wearTIP:-When ues reduced shank drill bit, it's important to maintain a 90-degree vertical angle to ensure precision and accuracy.-For power drills, it's recommended to use a model with a power rating of 750W or higher.-Use water or coolant to lower the temperature and prevent the drill bit from overheating, especially when drilling stainless steel materials.-For metals with high hardness and dense grain structure, use a slower drill speed than normal drilling, and cooling the workpiece will yield better results.-When machining thick workpieces, if there are issues with chip removal, promptly clear the debris.Package Content:-1pcs x Reduced Shank Drill Bit
