Description
Carbide Drill Bit Size — Drilling diameter: 2.2mm / 0.087″; tool flute length: 20mm / 0.79″; shank diameter: 2.2mm / 0.087″; overall length: 40mm / 1.57″; drilling direction: right hand; tool flute type: spiral; cutting hardness: HRC45
Wide Applications — Widely used for precision drilling of alloy steel, stainless steel, tool steel, carbon steel, cast iron, copper, hard plastic. Use on machining centers, CNC lathes, drill presses and bench drills.
Spiral Flutes — The spiral groove facilitates the export of metal chips, which saves time and effort in operation. Sharp flutes provide fast, neat and smooth cuts. Provides faster cutting speeds than other substrates and is harder but more brittle.
YG6 (C2/K20) Tungsten Carbide — It is a medium grain tungsten-cobalt alloy with an average cobalt content of 6%, high hardness, wear resistance, corrosion resistance, bending resistance, heat resistance, and resistance to stick.
Useful Tips — Keep cool and gentle when using. Not recommended for use with a hand drill (easy to shake, poor stability). Proper use can greatly extend the working life of twist drill bits. If there is a problem with chip evacuation, go back in time and remove the chips.
