Now make holes easily with the Hyperion HSS Step drill bit (titanium coated), this single bit will drill 10 different holes, ranging in diameter from 3mm to 12mm. This step drill bit has a titanium coating to run cooler and last longer. The twin flute design makes this step drill cut faster and smoother. These are very sharp and they cut clean holes with no chipping. The cutting surface has a much shallower angle, instead of a sharp V as in a regular twist bit. This cutting profile reduces or eliminates the breakout around the hole. Each smaller step center acts as a built in pilot for the next larger cutting surface. You can incrementally and step-by-step slowly increase the size of the hole from the pilot 3mm to the final size. Good for use on wood, plastics, thin and soft metals.

For the price these are great to have around instead of trying to rough out a hole to enlarge it. Keep these handy in your tool box and do it right when the job calls for it, instead of hacking with a regular drill bit. Say Goodbye to regular twist drill bits!!

Using a Step Drill Bit and Drilling Technique:

  • A step drill bit can be used to drill a range of different sized holes with a single bit. Since each bit size drill holes less than 5mm deep, a step bit is mainly used for drilling material having 5mm thickness.
  • The trick to using a step drill is, when do you stop at exact right size hole. So here’s an additional tip. Take a piece of tape and wrap it around the step exactly where you want to stop drilling. Then you just keep drilling until you hit the tape to get the exact size hole.
