About this item
  • ★ Drill Bit Size --- Cutting edge diameter: 21mm / 0.83"; shank diameter: 1/2"; effective cutting edge length: 48mm / 1.9"; cutting edge length: 82mm / 3.23"; overall length: 150mm / 5.9"; hardness: HRC62-63; cutting direction: right hand.
  • ★ Wide Applications --- Suitable for drilling common soft materials such as aluminum, copper, cork (soft wood), plaster, plastic, rubber, etc.. Reduced shank drill bits expand the size range capacity of portable drill chucks.
  • ★ Spiral Flutes --- Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, which saves time and effort in operation. Designed with small pockets to keep coolant near the cutting edge.
  • ★ High Speed Steel --- The twist drill bit is made of 4241 high-speed steel, with high hardness, good toughness, high strength, and wear resistance. Polishing reduces surface roughness for a smooth, flat surface.
  • ★ Useful Tips --- Use on drill presses and bench drills. The appropriate lubricant is beneficial for cutting or cooling, improving dimensional accuracy and extending tool life. Reduce forward and reverse speed. Use harder aluminum and wood.

What Is Included:
* 1 Piece x Reduced Shank Drill Bit

Applications & Features:
--- Suitable for drilling common soft materials such as aluminum, copper, cork (soft wood), plaster, plastic, rubber, etc. Widely used in maintenance departments, machine shops, and other industries. Reduced shank drill bits expand the size range capacity of portable drill chucks. Use on drill presses and bench drills. The appropriate lubricant is beneficial for cutting or cooling, improving dimensional accuracy and extending tool life.
--- The twist drill bit is made of 4241 high-speed steel, with high hardness, good toughness, high strength, and wear resistance. Polishing reduces surface roughness for a smooth, flat surface. Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, which saves time and effort in operation. Designed with small pockets to keep coolant near the cutting edge.

Useful Tips:
--- Drilling edges with burrs: Reduce the number of holes drilled and check various cutting conditions to ensure proper tool handling. Reduce forward and reverse speed. Use harder aluminum and wood. Drill metal with high hardness, the rotational speed should be slower than normal drilling.
