CoCud Drill Bit, 59/64" Cutting Diameter (23.416mm), 1/2" Reduced Shank 3-Flat 4341 HSS Nitriding Black 118° Cutting Angle Bits - (Applications: for Drilling Plastic Wood)

• ★ Drill Bit Size --- Cutting edge diameter: 59/64" (23.416mm); shank diameter: 1/2"; cutting edge length: 83.82mm / 3.3"; overall length: 152.4mm / 6", Included: 1 Piece x Drill Bit
• ★PRACTICAL PERFORMANCE --- The drill bit strikes a perfect balance between cost-efficiency and performance, featuring excellent machinability for general-purpose applications in normal working conditions.
• ★ Wide Applications --- For acrylic, plastic, wood, soft metals (Cu, Al alloys), commonly used in vehicle maintenance for tasks like drilling sheet metal fasteners, replacing bolt holes, installing brackets, and creating wire harness mounts (not be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials.)
• ★ 4241 High-Speed Steel (HSS) --- The 4241 high-speed steel (HSS) delivers optimal hardness and wear resistance. Featuring a nitriding black finish and 118° point angle design, it provides significant advantages in machining performance and tool life.
• ★ Useful Tips --- Ensure the drill bit is perpendicular to the workpiece surface—tilting can cause breakage or hole deviation. ​​For beginners: Always verify proper speed and feed rates before formal workpiece machining. For larger holes, a small guide hole should be drilled first to ensure precision.

Attributes: * Cutting Edge Diameter: 59/64" (23.416mm) * Shank Diameter: 1/2" * Cutting Edge Length: 83.82mm / 3.3" * Overall Length: 152.4mm / 6" * Material: 4241 High-Speed Steel * Finish: Nitriding Black * Cutting Angle: 118 Degrees * Style: Reduced Shank What Is Included: * 1 Piece x Drill Bit Applications & Features: ---Applicable materials: Acrylic, plastic, and wood. soft metals such as copper, aluminum alloys, carbon steel (use with caution for thick plates) ---Applications: The 4241 High-Speed Steel (HSS) Twist Drill is a versatile drill bit suitable for machining medium- to low-hardness materials, commonly used in vehicle maintenance for tasks like drilling sheet metal fasteners, replacing bolt holes, installing brackets, and creating wire harness mounts (non-precision applications) --- The 4241 high-speed steel (HSS) offers high hardness, excellent wear resistance, and good toughness. --- Nitriding black finish can enhance the corrosion and wear resistance of twist drills --- The 118° point angle ensures faster feed rate, higher machining efficiency, sharper drill tip, and more precise positioning. Suitable for handheld drills and bench drills in home repairs and light-duty machining. Useful Tips: ---The 4241 high-speed steel (HSS) drill bit is designed for low-load machining and should not be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials. ---Test Drilling on Scrap Material: Always perform a test drill on scrap material first to verify proper speed and feed rates before machining the actual workpiece.
