Polyurethane 3"x 2" Contact Wheel
  • 70A Durometer
  • 1/2" bore with bearings
  • Aluminum core with quality bearings installed.
  • The tire is 1/2" thick.
  • These are a low cost substitute for rubber contact wheels.
 On a typical 70A duro wheel, you can push in with your thumb and feel a slight give right under the pressure point where it might flex a few thousands of an inch. 70A durometer hardness is what 95% of the knife makers are using for their contact grinding wheels.

 You can use these in the No Weld Grinder Plans in place of the 2"x2" idler aluminum wheels or on the slack belt arm or even just on it's own tool arm. You probably couldn't tell these apart from rubber contact wheels comparing them side by side.

Polyurethane wheels are some what new to knife grinders but they have been around for decades in various forms and have a proven track record as contract grinding wheels. They do have a melting point of 185F degrees which is less than a typical rubber wheel so give the wheel a break to cool on extended grinding sessions. This is never going to be a problem for knife grinders but if I don't point it out, some one else will.

I had these custom made for my own shop and ordered in bulk quantity to get the cost down and to list here. I use these on my own No Weld Grinders I have built.
