arbor bushings of various sizes are included for each wheel, including 1/2", 5/8", 3/4", and 7/8".
This is the 150 grit one I bought. A 60 is available, but it's too rough to work with on a lathe. In general, rotary lawn mowers, dressing struck tools, etc., require a ratchet of 60.
There are 4,140 revolutions per minute
A deburring wheel such as this will work in a similar fashion to the Scotch Brite. Regardless of the type of metal removal, deburring, shaping or sharpening necessary, we offer the following The white aluminum oxide is used for the high-temperature treatment The best speed tool steels are brown aluminum oxide, silicon carbide for nonmetals, and speed tool steels are made of speed tool steels Usually, carbide tools and ferrous metals are used together.

This could have made me shy away from the game despite all the out of balance reviews. A 150 grit version of this Wheel was purchased. It had never occurred to me to balance a wheel before, so I did not know I could do that. There were detailed and clear instructions included in the package to set it up and get it balanced, and thus ensure that it works properly. It initially wobbled a bit when you put it on. I ended up getting it just right after 10 minutes of trial and error. There was no problem and all is well now. There is no difficulty in getting this adjusting done, and the wheel is good, although a bit too expensive for what it is compared to what it used to cost. I gave it 4 stars because the blue plastic insert is a poor Also, I had to superglue the wheel center pieces together and glue them to the surface. You may want to upgrade to an after market universal item of a higher quality. If you want to grind your own grains, I recommend this. In order to grind my lathe tools, I use it with a Oneway setup.
It had to be used for a while before I could review it. It was for sharpening High Speed Steel lathe tools that I was in the shop. This arbor bushing was too loose to fit the wheel, so it fell out of the wheel when I tried to unpack it. This is not a good sign for something of this nature. It nearly knocked the grinder off the bench when I placed it on my grinder. Once the grinder was clamped down and I adjusted the fitting on the arbor, the stone was dressed. Since it is a SOFT stone, I immediately generated a cloud of white dust as a consequence of the amount of material that came off of it. There is no excuse for not wearing a mask. Although the balance was improved, the spin was by no means I believe this will shorten the lifespan of the stone to an unacceptable degree due to its softness. It leaves a decent edge on my tools now, but I believe the frequent dressing As a result, I purchased a Trend diamond "stone" set and use that to hone the razor sharpness of my teeth. Use the grinder stone only to refine the shape, not to shape the You might want to pass on this product if you need to sharpen planer or chisel blades. If you need to work with mild steel and want a pretty smooth finish, you might want to consider this.
This item arrived in perfect condition after being double packed in air envelopes. As many reviews indicate that the bushings of this wheel are problematic and that the wheel is difficult to reinstall, I will describe what I did to mount and reinstall mine.
After taking off the old wheel, I cleaned up the shaft and cups. It is necessary to remove rust, accumulated slag, and other such material. Using a screwdriver, I first removed the bushing from the wheel and then mounted it to the cup. Tightening the nut with my finger, I held the outside cup tightly against the wheel. I spun the wheel and found it wobbled side to side and was about 3/16 out of true, so I removed it and repeated the process after repositioning the bushings in their original positions. Having done this four times I was able to get the wheel as flat as it would get, I sewed up the nut, switched on the grinder, and the grind began. It had some vibration as the grinder reached speed, but after it reached speed, there was no wobble and it showed a slight out-of-round. The vibration disappeared when I turned away from the wheel. There is no problem with the wheel spinning or working. Cool and fast to cut. In the case of a $20 wheel, you cannot expect a milled bushing to be included in the package. On top of that, the bushing does not affect how the wheel runs. On a cheap grinder, the surfaces of the cups and the way the wheel engages them determine how the grinder runs. Nevertheless, you might think that it will make a difference if you get a right sized bushing from McMaster or the nesting steel bushings available It is less expensive to have a little patience.
Several reviewers have recommended that it be replaced with a new wheel, mostly because of the cheesy center adapters. It would be better to turn a precise one out of delrin on the lathe and avoid this problem. My preparation wasn't enough to prepare me for the side wobble or the hole that was 1/8" off center. The adapters come with a lot of slop for a reason I guess. You can try grinding it true with a diamond grinding wheel (messy) or you can just throw it in the trash can. That was a significant amount of wasted time. I'm waiting on a 60 grit version of the same wheel to arrive. It will probably be easier to send them all back if it's the same type of off center wobbly wheel.
I was less than pleased with both packages I received. In addition to the arbor not being centered, they were both out of balance. In spite of machining replacement bushings and flanges, they were still worse than the factory wheels that come with the bench it is bolted to, which come with two sets of pucks to isolate the top from the bottom through bolted assembly. The performance of the sled has improved now that both sides and front have been trued up and balancing was done. At least Norton was cheap, but I expected a higher level of quality control.
This is a good basic stone with this minor flaw I believe this was listed as being 150 grit, but it was technically Very Fine. When lathe gouges are ground, they end up with quite a rough No, I wouldn't classify it as Very Fine. It is likely that I will need to buy another stone or hand finish the tool with an Arkansas stone to get good quality (
2) The included bushings for the arbor did not fit each other very well. Since they are 1/2" wide, I did not want them to sag or mount the stones out of round when I used them. Those who want to mount on shafts other than 1" may have to go to Ace to get some steel or bronze sleeves or bushings for them.
This is my second attempt. It was unsafe to use the first wheel because it was out of round and had lateral runout. Using the supplied bushings, the second try was just as bad as the first, for the bushings were so loose a rat could squeeze between them A round hole was not present in the center of the wheel, The 996x1 number. This is "006". There was about zero on the wheel. We made a bushing with a width of 97 inches In dead reckoning the wheel was then 27 thou out laterally, and about 15 thou out radially You will find washers there. The game was not balanced out of the box, even if it was possible to balance it. On my grinder shaft, runout is 1 thou, so this is significantly more visible and worse than my grinder shaft. It was thrown out with the bushings I'm going away. It was better to use the first wheel for the bushing set, but it was worse to use the second wheel.
