How many times can I trim my Enduro Flex Flap Wheel?


Walter’s Flap Wheels are made to be trimmed back atleast 3 times.  This allows for maximum life out of your flap disc.  Long life flap discs mean more money in your pocket.

  • First Trim = End of the ribbed design

  • Second Trim = End of the first arrow

  • Third Trim = End of the second arrow



How do I know when I should trim my Walter Flap Wheel?


When the overhang to your Walter Enduro Flex Flap Wheel is worn off it is time to trim it back.  This is an easily identifiable thing.  As soon as you only see orange from the hard shell of the flap wheel, than it is time to start trimming.



What do I need to trim my Walter Flap Wheel?


You need a vise, a metal cutting edge, and a grinder.  Walter does have a tool to trim back the Flap Wheel which is part number 06-B-901 but a piece of metal with an edge will work just fine.

  • Step 1

    • Secure the piece of metal or enduro flex cutting tool with a vise. (You must have the sharp edge facing out)

  • Step 2

    • Turn on the grinder with the Walter Flap Wheel inside. Slowly bring the backing of the flap wheel to the sharp, cutting edge.


    • Step 3

      • Trim the flap wheel back 1/4”. When the white adhesive begins to show lower the angle of your Walter Flap Wheel
