How to choose your grindstone:

1. Check the diameter and width of your grinding wheels.
2. Select the right diameter (in the desired width) below.
3. All grinding stones have a centre hole of 1" (25.4mm), check if you need reduction rings for your machine's shaft.

Remember to save the reduction rings in your old grinding wheel (press them out with a screwdriver) or order new ones here: [LINK]
