About this item
  • PACKING LIST: 6 packs of drill bits in 4.5mm cutting diameter, 47mm/1.85inch flute length, 80mm/3.15inch overall length, 135° split point tip.
  • FEATURE: The drills are made of M35 high speed steel with 4.50% to 5.50% cobalt content, which has excellent hardness, wear resistance, heat resistance and high crack resistance, making it suitable for machining hard metals. The gold finish effectively improves corrosion resistance and extends the drill bits' life.
  • APPLICATION: The M35 twist drill bit is suitable for professional machining, particularly for drilling stainless steel. It is also suitable for processing high-hardness materials, including carbon steel, iron, aluminum, copper, plastic, wood, and more.
  • NOTE: Position the twist drill bit at 90° to the surface of the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use cutting fluid to improve efficiency, extend tool life, and reduce material damage.
  • INSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page.
  • In stock, ready to ship

Product Description:
FEATURE:
M35 high-speed steel drill bits, containing 4.50% to 5.50% cobalt, has high hardness. These bits are recognized for their exceptional wear resistance, impressive heat resistance, and high crack resistance, making them suitable for machining high-hardness metals.
Gold Finish can be used to improve the surface properties of drill bits' materials and increase their wear resistance and corrosion resistance, thus extending the service life of the drill bit and working efficiency
The 135-degree split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.

APPLICATION:
The 5% cobalt high-speed steel drill bits are specifically designed for cutting hard metal, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.

PACKING LIST:
-Cutting Edge Diameter: 4.5mm
-Shank Diameter: 4.5mm
-Flute Length: 47mm/1.85inch
-Total Length: 80mm/3.15inch
-Package Content: 6pcs x Drill Bit

NOTE:
Applicable coolant, during the machining process, friction between the drill bit and the material generates a significant amount of heat, coolant can effectively reduce the temperature, preventing the tool from overheating, and extending the drill bit lifespan.
