  • US-105 = 305mm
  • US-103 = 295mm

As noted, the US-103 is 10mm shorter to accommodate the 200mm grindstone which is 10mm thinner than the 250mm grindstone.


10mm difference in length???

250mm - 200mm = 50mm

The width of the stone... 50mm vs 40mm

Yes, the 250mm grindstone is 50mm wide, and the 200mm grindstone is 40mm wide.

Rich is correct about the edge thickness of the two wheel sizes. However, the thickness of the two sizes at the indentation for the bore is almost identical. That is the reason why either size wheel will fit either size machine.

Please note that although this is possible does not mean that it is practical.

Sort of off topic of the USB measurements but....
you are saying that a worn down 250mm wheel (blackstone, say) would be OK to mount on a T4 if someone wanted. I ask as someone was wondering if Tormek had plans to make a 200mm blackstone.

Yes you can mount a worn down 250mm stone onto a T-4.  For example:
