Sharp spiral flutes provide neat and smooth cuts. High cutting edge strength, fast cutting speed. Spiral groove facilitates the export of metal chip, saving time and effort in operation.Gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface.Suitable lubricant is conducive to cutting or cooling, making cutting easier and improving smoothness and dimensional accuracy. It can help to extend the service life of tools.Widely used for drilling stainless steel, aluminum alloy, iron, copper, wood and plastic. Perfect tool for maintenance departments, machine shops, and other industries. Used on electric hand drill, drilling machine and bench drill.When using hand-held electric drill, the recommended speed is 100-1000rpm/min; the larger the drilling diameter, the slower the drilling speed. Drill metal with high hardness or foreign substance, the rotational speed should be slower than normal drilling.
