About this item
  • 1- PACKAGE CONTENTS - 1 pack of 5mm drill bits, with a 86mm (3.39") overall length and 44mm (1.73") flute length, featuring a 135° split-point angle for reduced walking and enhanced drilling accuracy in metal, wood, and plastic applications.
  • 2- MATERIAL - M42 cobalt high-speed steel drill bits, with a cobalt content 8%, deliver superior hardness and durability. Known for outstanding wear and heat resistance, as well as high crack resistance, these bits excel in drilling high-strength and difficult-to-machine metals. The titanium nitride (tin) coating enhances surface characteristics, boosting wear and corrosion resistance. This treatment contributes to prolonged tool lifespan and improved operational efficiency.
  • 3- APPLICATION - For precision drilling in hard metals, hardwoods, composite boards, and carved components, these bits efficiently process dense woods like rosewood and teak. The cutting edges maintain exceptional sharpness even at high RPM, making them perfect for detailed craft carving, mortise-and-tenon joinery, and thin wood sheet drilling - the ultimate tool for woodworking DIY, furniture manufacturing, and artistic carving applications.
  • 4- HIGH EFFICIENCY - Cobalt high-speed steel extended service life & reduced wear. Compared to standard HSS drill bits, it offers a 3–5 times longer tool life, significantly lowering the cost per hole. High-efficiency production​​: Its balanced wear resistance and toughness ensure reliable performance in automated equipment and high-volume machining.
  • 5- TAKE NOTICE OF - Position the twist drill perpendicular (90°) to the workpiece surface. Begin drilling at low RPM (500-800) to establish a small hole, then adjust speed based on material: higher for wood, lower for metals. Use cutting fluid to effectively reduce temperature, minimize wear, and extend drill bit life

Product Description:
APPLICATION
-Precision drilling in hard metals, stainless steel, alloy steel, etc. (and soft materials like acrylic, plastic, wood, etc.)
-High-density hardwoods (rosewood, teak, etc.)
-Composite boards & carved components, detailed craft carving & mortise-tenon joinery
-Woodworking DIY/furniture making/artistic carving

ABOUT THIS PRODUCT
-M42 cobalt high-speed steel 5mm drill bits, with a cobalt content 8%, deliver superior hardness and durability. Known for outstanding wear and heat resistance, as well as high crack resistance, these bits excel in drilling high-strength and difficult-to-machine metals.
-Titanium Nitride coating is engineered to improve twist drill operation through key properties: exceptional wear resistance from increased hardness. These combined effects significantly enhance durability and output.
-The 135-degree point design significantly reduces bit wandering, ensuring precise starts and smooth drilling in tough materials such as hardened and stainless steel.

SPECIFICATION
-Cutting Diameter: 5mm
-Flute Length: 44mm (1.73")
-Overall Length: 86mm (3.39")
-Cutting Angle: 135°
-Package: 1 pack of cobalt drill bits

NOTE
-Maintain 90° perpendicular to the workpiece
-Start at low speed (500-800 RPM), then adjust
-Use cutting fluid to effectively reduce temperature
-Always wear safety goggles and secure the workpiece
