Contour Sander FAQs and Troubleshooting

The Contour Sander fits most 4″ (100mm) and 4 1/2″ (115mm) angle grinders. However, when choosing an angle grinder to suit the blade, you should look for the following features:

  • An auxiliary handle
  • The on/off switch positioned on the top or side
  • At least 550 Watts power
  • Should have a spindle thread of: M14 (AUS and UK ) |  M14 (Europe) | 5/8″ (North America)

Yes, as long as the grinder is powerful enough and runs at a speed of 9000RPM or higher.

YES! Using the blade on the flat, and working the machine with two hands ensures the best visibility for the operator and also means that hands are kept well away from the work area.

Possible cause: Incorrect thread or adapter

Solution: Check thread, locate correct adapter

 

In Europe the shafts suits an M14 thread

In North America the shaft suits a 5/8″ UMC x 11 thread

In Australia the shaft suits an M14.
