Make Most of Cobalt Drill Bits with These Tips

3/16"X3-1/2" Cobalt Drill Bits Set HSS M35 Jobber Length Metal Drill Bit 10 Pack

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.
