2.No center punch is needed-the aggressive 135° Quick-Cut points are self-centering and penetrate quickly

with lesspressure. Will not "walk" or "wander".
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.

Make Most of Cobalt Drill Bits with These Tips

Be Vertical

  • Keep the drill bit vertical with the stuff's surface to be drilled.
  • Tilted bit is prone to break during drilling.
  • Be sure to make both the bit and the workpiece stable.

Do It Slow

  • Drilling metal requires low RPM. Please use a device of which the drilling speed can be adjusted.
  • Be careful when you use an electric drill. The RPM could be set too high.
  • The thicker the bit, the slower speed should be.
  • If you're not sure, please start from the lowest RPM and pressure.

Stay Cool

  • Friction between bit and metal will accumulate an amount of heat.
  • It's necessary to use cooling liquid during drilling to keep the bit cool. Otherwise, the bit may fry(melt) or only last a short time.
  • It's both ok to use lubricant oil and to pour water.

Right Drilling Device

  • It's highly recommended that you use a drill press to drill thick metals. It's stable, powerful and (RPM) adjustable.
  • If a drill press isn't available, electric drill or charging drill will do the job, too. However, it's more likely you'll meet problems unless you're really experienced.
