Applications & Features:
--- Widely used for precision drilling of alloy steel, stainless steel, tool steel, carbon steel, cast iron, copper, hard plastic in maintenance departments, machine shops, and other industries. Use on machining centers, CNC lathes, drill presses and bench drills. Selecting the correct lubricant can facilitate cutting or cooling, making cutting easier, improving dimensional accuracy and extending tool life. Drill metal with high hardness, the rotational speed should be slower than normal drilling.
--- YG6 (C2/K20) tungsten carbide is a medium grain tungsten-cobalt alloy with an average cobalt content of 6%. The solid carbide drill bits has high hardness, wear resistance, corrosion resistance, bending resistance, heat resistance, and resistance to stick. Provides faster cutting speeds than other substrates and is harder but more brittle. Carbide material with good drilling properties ensures high working efficiency. 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.

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. Be careful and control your CNC speed.
