La pietra oleata di ricambio a grana fine NORTON IM9 India per il sistema di affilatura IM313 è realizzata in ossido di alluminio a grana 320, adatta per l'affilatura e la manutenzione dei taglienti in acciaio; produce taglienti durevoli e lisci ed è preferito per tolleranze strette. La pietra è preriempita di olio per risparmiare tempo ed eliminare la necessità di immergerla prima dell'uso. L'olio impedisce al metallo di legarsi alla superficie abrasiva eliminando l'abrasivo ei trucioli di metallo. Questa pietra oleata è comunemente usata per sostituire una pietra nel sistema di affilatura Norton IM313, o come pietra da banco, per ripristinare i taglienti su utensili a tagliente diritto come scalpelli, coltelli, lame per pialla e strumenti di precisione.

Il tipo di ruota è 01 con un diametro di 6 pollici e grana molto fine. Dimensioni: 6 x 1 x 1 pollici con 1 pollice di spessore. Viene fornito in confezione da 1 mole. Dimensionato come una mola da 6 pollici con un legante vetrificato, questa mola è progettata per mantenere una forma superba e resistenza all'usura. Questa ruota da banco e piedistallo è appositamente progettata per acciai al carbonio teneri, acciai per utensili e superleghe. Questa smerigliatrice da banco è un'ottima scelta per la sbavatura e l'affilatura di utensili su smerigliatrici da banco e su piedistallo con velocità operative fino a 4140 giri/min. Le mole per smerigliatrice da banco e piedistallo Norton Premium sono progettate con ossido di alluminio bianco di qualità per la sbavatura e l'affilatura degli utensili.

Softer than expected
Nice stone, easy to use. My main comment it that it is wearing very fast, maybe 1/2” in a couple of months with occasional hobby use. I’m probably pushing it too hard on larger mild steel, but I get a pile of dust during use. Likely great for hss tools and bits.

Good Wheel, Questionable Shipping and Handling
SHIPPING AND HANDLING. I ordered four grinding wheels from amazon for my two bench grinders. Two were six-inch Norton white wheels, one was a Norton seven-inch regular wheel, and one, a seven-inch Forney. In each case, the wheel was flopping around in the box with an ineffective bit of packing material. The Forney wheel was bare naked and had worn a hole in a pack of countersink drills. It was happily unsharpening them. The Norton wheels were in their own box inside the amazon package. The white wheels arrived undamaged. The seven-inch wheel had a chipped edge. Despite the poor amazon packaging, it probably was damaged BEFORE shipping because the internal box was dirty and scuffed with corners split. Amazon has always had a stellar reputation with me but (are you listening amazon?) they need to do a better job packaging (and handling) grinding wheels. Damaged wheels can fly apart explosively. For some disturbing reality, Google "grinding wheel deaths." Following are salient points regarding handling and storage from the government standard on grinding wheels, ANSI B7.1-1970. 1. Handle wheels carefully to prevent dropping or bumping. 2. Do not expose to high humidity, water or other liquids. 3. Do not expose to freezing temperatures or any temp low enough to cause condensation. 4. Perform the `ring test' to detect hidden cracks in vitrified wheels. For the ring test, support the wheel through the center hole with your finger or pin and tap the side of the wheel gently in several locations with a non-metallic object, such as the handle of a screwdriver. You should hear a clear metallic ring. If you hear a deadened thud, DO NOT use the wheel. INSTALLATION. From my perspective, there are three major considerations: 1. Safety. Perform the ring test, don't exceed RPM rating, have all guards in place, and stand to the side for a full minute before starting to grind. 2. Wobble. Clean the surface of the wheel flanges of any label or blotter residue from the previous wheel. If necessary, true the surface of the flange by rubbing it on a piece of fine sandpaper that is laying against a flat surface. Rotating the flanges with respect to the wheel sometimes helps. 3. Out-of-Round. Dress the wheel. I use this wheel dresser, it seems to work well. http://www.amazon.com/gp/product/B002KNOK9W/ref=oh_details_o01_s00_i00 EVALUATION OF WHEELS. The wheels that I put on my good grinder (yeah! Milwaukee 1980's vintage) were fairly well balanced from the beginning. The inner flange is cast with a machined face and a collar to hold it vertical on the arbor. The wheels had about 1/32 inch or less wobble and 1/32 inch or less out-of-round. I left the wobble, but dressed the wheel so it was perfectly round. There is very little vibration at full speed, with slight resonances as it slows down. I saw no difference between the Forney and Norton wheels. I put the Norton white wheels on my cheapo (boo! Craftsman 21st century vintage) bench grinder. The one wheel seemed well balanced. The second wheel wobbled like crazy. It was going a full 1/8 inch from side to side. I played around with the flanges and was able to reduce the wobble to less than 1/32 inch. It appeared that the cheap stamped flange was not seated properly in a lip in the arbor. After dressing the wheels, the Craftsman ran as smooth as the Milwaukee. I am happy with the Norton grinding wheels. And contrary to the experience of other reviewers, all came with adapters down to a ½-inch arbor. I may update this review after using the wheels for a while. I'll try to keep it shorter (-:

Works great, with two caveats
These wheels are fantastic compared to the "cheap" alternatives. Cheaper wheels cut about like concrete -- i.e., they rub and generate heat without removing much metal. Norton white wheels, on the other hand, are "softer" and are designed to continually shed the top layer of abrasive revealing fresh, sharp grains to cut metal quickly without heating it. There is a night and day differencce between cheap wheels and these Nortons when you want to rapidly remove a lot of metal. (By the same token, if you are just touching up tools that aren't terribly dull, then the cheap wheels will probably satisfy you.) While Norton wheels are very good at what they do, there are two issues to be aware of. The first is applicable to ANY wheel, no matter the brand or quality: ALL wheels must be dressed the first time they are mounted to true them up. No wheel can be manufactured with a precisely centered arbor hole, and a lot of grinders don't even have a motor shaft that spins perfectly true. By dressing the wheel immediately after mounting, any eccentricity is removed and the wheel should be fairly well balanced. I don't blame Norton for this issue because I don't believe any other wheel maker can do better -- failure to dress your wheel is a user problem, not a manufacturer problem. (Note that a side-to-side wobulation is usually a problem with your grinder's mounting flanges, especially on cheap grinders.) The second problem is the plastic adapters supplied with the wheel. I was still able to get my wheel to run true using them, but I had to remove a lot of material off one side of the wheel by dressing it excessively. This issue definitely IS Norton's fault, however remember that we as consumers tend to demand price before quality, so Norton is just doing exactly what we want -- supplying cheap adapters. So, if you are serious about grinding, the real solution is to go out and purchase metal arbor adapters that will be on-size and run true.

NO WOBBLE, HARDLY ANY DRESSING TO DO...PERFECT thanks to using a Raptor R3X bushing!
After reading all the bad reviews I searched for an answer and truly believe I found it! Craft Supplies USA sells what they call the Raptor R3X Grinding Wheel Bushing 2 Piece Set. This is a wonderfully made flange with an attached bushing that you can order to either fit a 1/2" or 5/8" motor shaft. It comes as two pieces, the flange with the busing is all one piece, and then there is another flange for the other side (I did not use this, but rather used the original inner flanges for the grinder). The bushing is 3/4" long, but will work on a 1" wide wheel without problem (the wheel I ordered is 6x1x1). I ordered two of these sets as the past owner of my 1920's grinder had ended up using just big washers as flanges on the outside of the wheels. I ordered the sets and then ordered the Norton wheel, so I was ready to go when the wheel arrived. I couldn't be more pleased!!!! I didn't waste time with the plastic bushings that were supplied as everyone seems to agree they are not the best. I pulled them out and stuck my new Raptor bushing flange in and put it on the grinder. NO WOBBLE as so many had described, and it was so perfectly in round that I doubt there is even 1/32" variance to be dressed (yes, I think it is less than that...maybe 1/64"). WOW! Very pleased! As far as shipping goes, I ordered the wheel alone so it would be all that was in the box from Amazon and not be bumping into other things. It was sent in a box similar to what Amazon sends books in, so there was no wiggle room in the box. It arrived in perfect condition. I truly believe the Raptor R3X Grinding Wheel Bushing 2 Piece Set is the answer...yes you spend more money to get a great bushing, but it is well worth not having to deal with so many issues on any grinding wheel you might buy that comes with plastic bushings.

Very poorly balanced
The white grinding compound for high speed steel does not get the tool as hot as regular grey carborundum does. This wheel works as it should. I am giving it one star because I had to bolt the grinder to the bench as it vibrates so bad way worse than the cheap wheels that came with the grinder.
