Anyone use these? I just picked up a 120 grit (a bit too fine for my tastes) and it seems real soft. I usually grind 5-8 gouges at a time and I had to reface it twice during my last sharpening session.
lower grits would be for reshaping and 80 or 120 for all around sharpening. If you have found them locally at the same price, buy them locally. Te Norton SG is a great wheel from what I have been told (Stuart Batty highly recommends them...)odie said:I am about to purchase a couple of the Norton SG 80gt (I think) wheels I see on CSUSA. They are expensive at 70 bucks a pop. I found them locally, but at the same price. Anyone know of a cheaper source that would be worthwhile to pursue?

Ever since the 3X wheels came out I have wondered if they were the same wheels at a new lower price because of better production methods. Sounds like they are different wheels. I don't shape my tools that often so opted for two 80 grit.

Has anybody compared the Norton 3X SG from Hartville Tools to the SG from CSUSA side by side? They are only 40% of what CS is asking for. Those from CS are real nice - cut fast, do not load up, run cool and resist grooving. The only downside is the big price tag. Since the big price gap, are we comparing the same product?

I wondered the same thing, so I contacted Norton. They told me that the difference is the proportion of Seeded Gel to AO. 30% SG for the 3X wheels and 50% SG for the 5SG wheels.
I wouldn't use the 3X wheels to sharpen turning tools because their hardness is "I". My understanding is that 5SGK wheels are the ones recommended for high speed turning tools.
