sourcing map 22.2mm (7/8") Drill Bit 1/2" Reduced 3-Flat Shank 4241 High-Speed Steel Bits Black and Gold Finish 118°Drill for Light-duty Machining Acrylic Plastic Wood Soft Metal

• SIZE: Cutting edge diameter: 7/8" (22.23mm), shank diameter: 1/2", flute length: 74mm/2.91 inch, total length: 150mm/5.91 inch, package content: 1 Pcs x Reduced Shank Drill Bit
• MATERIAL: The 4241 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. The Black and Gold surface treatment enhances the corrosion resistance and wear resistance of the drill bits, effectively extending their service life.
• 118-DEGREE POINT TIP: Conventional Point, not easy to slide, suitable for wood, plastic soft metal, and other materials drilling, widely used in daily operation, more appropriate for home and light industry use, simple operation, strong adaptability.
• WIDE APPLICATIONS: For general metalworking & light-duty applications at low speeds. Perfect for drilling iron, copper, aluminum alloys (medium-low hardness metals) and wood. A cost-effective solution for basic machining needs. The Black and Gold surface treatment enhances the corrosion resistance and wear resistance of the drill bits, effectively extending their service life.
• TIP: When using a large drill bit, it’s best to start by drilling smaller holes. This makes it easier to create larger holes accurately, select the appropriate coolant when running at high speeds when using hss drills to prevent tool overheating and wear.

Specifications: -Cutting Edge Diameter: 7/8" (22.23mm) -Shank Diameter: 1/2" -Flute Length: 74mm/2.91 inch -Total Length: 150mm/5.91 inch -Split Point: 118°; Material: -The 4241 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. Surface Treatment： -Black and Gold, while its surface treatment provides enhanced oxidation and corrosion protection, extending drill bits’ service life and making them suitable for drilling hard metals and other materials. TIP: -When using a large drill bit, it’s best to start by drilling smaller holes. This makes it easier to create larger holes accurately. -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 hard metal like stainless steel materials.
