    • Application Notes

    Using VersaDrive Drill Bits to drill holes with an Impact wrench:

  • VersaDrive Impact wrench drill bits work by utilising the high torque rotary drive of an impact wrench in a conventional rotary drilling operation.?
  • The impact wrench mechanism should not engage or impact when drilling, if this occurs, too great drilling pressure is being used and should be reduced.
  • Impact wrench driven drill bits will transfer less torque then a conventional drill bit used in a rotary drill, meaning less fatigue for the operator.
  • An experienced operator can utilise a higher torque impact wrench or setting (if variable speed) to increase the speed of the job.
  • The drilling time when used with an impact wrench is slightly slower but comparable to a standard rotary pistol drill.
  • Using VersaDrive Drill Bits to enlarge existing holes with an Impact wrench
  • VersaDrive Drill Bits can be used to enlarge existing holes with an Impact Wrench. However, by default this process will utilise the impact operation (as opposed to rotary only) meaning a possibility of reduced drill bit life. For effective use the increased hole size should be no greater than two thirds of the starting hole size.
  • For hole sizes larger than 12mm we recommend the use of a reamer where possible.
