  For longer hole saw life, use the following instructions:

  
  
  
  
  1. Use the correct mandrel for the diameter hole saw being used.
  
  
  2. Use pin-type mandrels for hole saws larger than Ø32mm. When mounting the mandrel, lift the pins up and then screw the mandrel down into the hole saw as far as it will go. It is important that the pins holes are securely located in the hole saw.
  
  
  3. Use the correct rotation speed. If the speed is too high or too low will have an effect on the cutting edge on the hole saw and decrease the life expectancy.
  
  
  4. Clear away wood chips or iron filings frequently to prevent the hole saw from overheating.
  
  
  5. Always apply the necessary pressure for the intended use. Too much pressure can destroy the teeth when cutting in metals.
  
  
  6. Keep the drill going straight to avoid binding the hole saw.
