I decided to start a new thread as I just got back from HOURS of searching for a finer-grit wheel than what is sold as standard 4.5" grinding wheel: Home Depot and Lowe's ALL sell and ONLY sell the Type 27, whatever this means it has to do with grit and this is a COARSE wheel, there is none other in the aisles. Northern Tool also sells the T27 and a few others which are not even labeled but it's all the same COARSE grit. Napa sells the 24 grit and the 36 grit, I stared at BOTH for a LONG time and could not see much difference, however the 36 is finer than the 24 - Doing a search on Yahoo for 'fine-grit grinding wheel 4.5" fine grit' revealed to me (finally) the HIGHER the number grit, the FINER it is, hence why I figured out 36 grit is finer than 24... However, to get a truly nice FINE grit, one would be looking at a wheel with at least 80 grit or higher, here's the info: Grit: 80 (Fine), Grit: 100 (FINE), Grit: 120 (X-FINE). But, where to find them... So far: http://www.aloghomestore.com/tools-makita.shtml Shows a 50-grit, which is at best a medium grit, thou still a bit coarse... Just in case, here's the model st0137-makita-4-1/2 And after many hours of fruitless searching, I give up... If anyone finds a 4.5" fine grit (at least 80 grit would be nice) wheel, please be so kind let us in LOL! I think in the end one needs a bench grinder but why wouldn't someone make a 4.5" wheel like this, absolutely nuts!
