I was just reading the current post on CBN wheels, 80g vs 180g. I am contemplating buying one(or 2) myself to go with my recently acquired Oneway grinding system(stealth gloat). I ran across this diamond wheel (http://www.woodcraft.com/Product/2021136/25960/WoodRiver-Diamond-Grinding-Wheel-8-120grit.aspx) on sale at Woodcraft recently and I was wondering how diamond compares to CBN. I realize that diamond is generally used for carbide tools and the CBN is design for HSS but if the diamond will cut carbide it will cut HSS. The price was really good on the diamond wheel, a good $50 less then the CBN.
A couple of cons I know:
- The Diamond wheel is only 1" wide vs the CBN at 1.5"
- Not sure of the performance/quality vs the known(as repeatedly stated in posts here on SMC) performance of the CBN
- Limited to 120g
Some Pros:
- The diamond wheel has a 5/8" arbor hole, no adapter needed.
- I have a metal lathe and a mill with carbide tooling that could be sharpened.
If some of you could add to the Pros & Cons list between the two types of wheels it would be helpful though it is not necessary to rehash the comments made in the recent CBN thread.
Edit: Just saw Dan Hintz comments on the possibility of the diamond clogging, perhaps I need to consider one of each, hmmm.
