Feature

●★Drill size: cutter diameter: 20mm/0.79"; shank diameter: 1/2"; cutting length: 80mm/3.15"; total length: 150mm/5.9"; hardness: HRC65-66; cutting direction: right.
●★Wide Applications --- For drilling stainless steel, aluminum alloys, cast iron, carbon steel, copper, hardwood and hard plastic. Can be used on drill presses and bench drills. Short shank drill bits expand the capacity of the size range of portable drill chuck.
●★ Spiral Flutes --- The sharp spiral grooves guarantee fast, clean and smooth cuts. The spiral groove facilitates the removal of metal chips, saving time and effort in operation. Designed with small pockets to keep the coolant close to the cutting edge.
●★ 6542 high-performance steel --- The twist drill has high hardness, toughness, strength. The black nitride coating provides excellent resistance to wear, corrosion and high temperatures. Ensures better application of lubricant, smoother drilling.
●★ Useful Notes --- The right lubricant is helpful when cutting or cooling, increases dimensional accuracy and extends the life of the device. Reduce the speed when driving forward and reverse. Use harder aluminium and wood.

Applications and features:

--- Widely used for drilling stainless steel, aluminium alloys, cast iron, carbon steel, copper, hardwood, hard plastic and other metal materials in maintenance departments, machinery shops and other industries. For use on drills and bench drills. The appropriate lubricant is helpful when cutting or cooling, increasing the dimensional accuracy and life of the equipment.
--- The twist drill bit is made of 6542 high-speed steel with high hardness, good toughness and high strength. The black nitride coating has excellent wear resistance, corrosion resistance and high temperature resistance. Provides better lubricant application, smoother drilling and is more durable and corrosion resistant than traditional silver surfaces.

Notes:
--- Drill edges with burrs: reduce the number of holes drilled and check different cutting conditions. Pay attention to proper handling of the tool. Reduce forward and reverse speed. Use harder aluminum and wood. Drill metal with high hardness. The speed should be slower than normal drilling.
