uxcell 28mm Drill Bit 1/2" Reduced Shank 4341 High-Speed Twist HSS Nitriding Black 135° for Light-Duty Soft Metal Aluminum Alloy Wood Plastic

uxcell 28mm Drill Bit 1/2" Reduced Shank 4341 High-Speed Twist HSS Nitriding Black 135° for Light-Duty Soft Metal Aluminum Alloy Wood Plastic

SIZE: Cutting edge diameter: 28mm, shank diameter: 1/2 inch, total length: 150mm/5.9 inch, flute length: 59.436mm/2.34 inch, small and easy to carry, suitable for various material MATERIAL: Precision-treated 4341 high-speed steel delivers superior hardness, making it ideally suited for high-friction applications. The material delivers exceptional wear resistance, while its nitriding black finish provides enhanced oxidation and corrosion protection, significantly extending tool service life 135-DEGREE SPLIT-POINT TIP: Provides excellent processing stability, is suitable for hard metal, and can effectively reduce the risk of cutting edge chipping, improving drilling efficiency and hole quality. WIDE APPLICATIONS: These drill bits are specifically designed for metalworking applications, effectively drilling through various metals, including thin steel, thin stainless steel, aluminum, copper, and brass. (They are not suitable for application with super-hard metals) TIP: Use a slower drill speed. Drill a smaller hole first to ensure precise positioning and prevent drill deviation. When drilling thick workpieces, use water or coolant to lower the temperature and prevent the drill bit from overheating. Specifications:
-Cutting Edge Diameter: 28mm
-Shank Diameter: 1/2 inch
-Cutting Edge Length: 59.436mm/2.34 inch
-Total Length: 150mm/5.9 inch
-Split Point: 135°

Material:
-The 4341 High-speed steel twist drill bits delivers high hardness, wear resistance, and toughness for light-duty machining of low-carbon steel, aluminum, brass, acrylic, plastic, and wood, offering optimal cost-performance balance for small equipment, with strong adaptability, also including auto repair, modification, appliance installation repair

Surface Treatment：
-The black nitriding finish 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 wear

TIP:
-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.
