- Twist Drill Bit: Cutting edge diameter: 14mm / 0.55", 14.5mm / 0.57", shank diameter: 10mm / 0.39"; Total Length: 150mm / 6.0". Features high hardness, good toughness, high wear resistance, suitable for most general purpose applications.
- Wide Applications: Widely used for drilling stainless steel, aluminum alloy, iron, copper, wood and plastic. Used on electric hand drill, drilling machine and bench drill. Drill metal with high hardness or foreign substance, the rotational speed should be slower than normal drilling.
- Special Design: Sharp spiral flutes provide neat and smooth cuts. Spiral groove facilitates the export of metal chip. Reduced shank drills expand the size range capacity of a portable drill chuck. Tri-flat on the shank of drills are constructed for tighter clamping and precise drilling.
- Titanium Nitride Coating: 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.
- Tips: Suitable lubricant is conducive to cutting or cooling, making cutting easier and improving smoothness and dimensional accuracy. When using hand-held electric drill, the recommended speed is 100-1000rpm/min; the larger the drilling diameter, the slower the drilling speed.
