Can this be used for tool lapping? What are the grits? For tools I see numbers like 120, 400, etc., indicating coarser (small numbers) to finer.

This would be inappropriate for use as a lapping compound. Amazon does sell lapping compound, I've purchased it .

When used for sharpening knives, chisels, and planes, I have heard people discuss 20 year life. I have seen NO perceptible wear in my four DMT stones, some of which are several years old. I read a review where someone was using it as sandpaper (really???) and was disappointed, although I bet it was clogging rather that losing the diamond grit. The extra coarse is for reshaping the cutting edge - my newest stone - and it is likely to replace my grinder (which led to too many funny shapes and angles) I got the coarse to flatten my waterstones, but found it also worked great on dull blades (as the first step). Someone said they used the extra coarse to flatten waterstones, but I don't want to remove that much material - regular coarse works fine on all my waterstones. There is no medium The fine is outstanding for a quick touch up of chisels or for extreme sharpening of kitchen knives. Big advantage is soap and water clean up of kitchen contamination. The extra extra fine (it has a different name) is disappointing. I found it worth going to waterstones after the "fine" DMT. I use 4000, 8000 and now 13000 grit waterstones, occasionally followed by honing compound.

You can zoom in on the product picture to see what grits... They should have it posted in the info section though. 1 very fine - 220 2 extra fine - 320 2 super fine - 400

Not very coarse. I used it to sharpen some really old chisels. The instructions are very vague. Few words and you must be an expert in interpreting hieroglyphics. As far as coarseness goes, I can't tell which side is which. I think the lighter side is the fine side. In retrospect, I wish I had bought a water stone or a diamond sharpener (like the DMT W7EFC Diamond Whetstone for about $20. I did not have the knowledge or the cash. It's OK. I will sharpen chisels and rather nicely, but with much effort. The little bottle of oil will last quite some time. I use an old flat file to flatten the stone occasionally. Not very coarse.

I use them for a cosmetology school. We file the free edges & use them to buff the shine off. I think they are more medium to coarse grit.

I use a 300 & 600 grit stone before I use this and am very pleased with the results. I hope that helps.

No, the 1000 grit side is full diamond grit, only the 300 grit side has the clearing channels.You're not really removing much material with the 1000 grit so I've found it to be okay.Use lapping fluid (I use windex window cleaner) and keep it clean.

Yes. In fact, if you came to me to ask which tool to use to sand down clear coat to 800-grit level smoothness, I would say a random orbital sander(5-6" is most common for the curves of a car or boat, 10-12" is faster for 50+ft boat or large trailer) is beat. The weight and size of this particular model makes it easy to sand at shoulder height or above your head or for long hours. I had this model for years and swear by it. If this is a one time project or smaller than a table, save money by just buying a 5-6" random orbital palm sander. I am heavily disappointed in the crap quality of the buffer pad. The sponge is glued on and comes off as soon as its hot. The nature of sponge allows it to just peel away. So don't get excited about the 2-in-1 option. For best results when using sander, use 220 grit to get through clear coat, 180 is pushing it and 120 may take off more than you want but is my favorite if you can do it right. 120 (as long as you don't cut through at an angle by accident) will take off the most bang for your buck. A 2'x2' area can be done in like 45-60 seconds. Use the upper right quadrant (12-3pm on a clock) to take off layers in a methodical up down or left right slightly overlapping motion. As you leave an area, Go back over Lightly with pressure more evenly distributed on pad. Then go over with 220 same way. Then probably 400. Past that you are getting into wet dry paper and I have never used this machine with wet dry. It's a great way to get to 800. Make sure you have a pad, a sponge, a cloth or something to keep your fingertips from leaving an inconsistent finish. Or just make your hand into a pad like surface. The short answer? Yes.

I'm not sure of the numbers but you would definitely want a finer grit to finish off your blade. That probably doesn't help you at all though LOL. I went ahead and bought a better stone.

I don't remember exactly the grit numbers but it's basically low, med, high and a couple of each type if I recall. It's enough to do small projects but I opted to buy additional papers with it, and was glad I did cause I was doing a fairly large project - restoring an antique foyer table.

It depends on how polished you want the tool to be. Obviously 1000 grit is not 8000 so if you want that refinement the answer is no. However, personally I used to use aluminum oxide sand paper on a 3/8" piece of glass to sharpen chisles, plane irons, gouges, etc. finishing at about 320 grit. To me it was good enough for bench chisels and carving tools. At 1000 grit, the diamond stone is way better and it cuts in a fraction of the time. I tend to want to be practical at the quality of a cutting edge and not at the expense of time. I can sharpen a bench chisel in about 5 minutes with the diamond stone. I can't come close to that with water stones. They are too slow for me.

Obviously Home Depot and Lowes will carry the bulk of what you will need for your project, but if you have a more non-standard size or grit that you are looking for check out: http://www.aaabrasives.com/. If that still doesn't get you what you need, Google the make & model of your sander and look for its specifications: this will tell you exactly what you need.

As with sandpaper the lower the number the more aggressive the stones are in removing material. The 1500 is the last stone used as it is the least aggressive. The 120 is used to remove any chips in the blade and if you are going to cut a new edge profile. After the first time I only use the 600 and 1500 to sharpen my blades depending on the condition of them.

The grit number is the measure of the coarseness or fineness of the grinding material. The higher the number the finer the grinding material and the smoother and sharper the surface finish of the knife will be. Conversely the lower the grit number the courser the grit material. the course material will remove metal faster but leave a rougher finish. You should start with a course material and work down to a fine material to get a nice smooth finish. That is start with a low grit number and work up to a high grit number.

I use the 120 and 240 grit. Remember the higher the grit number the smoother the nail will be and the less likely it will split and crack.

I really don't know exactly. However, if the stone is an oilstone, and I believe it is, then its probably 240 grit for "medium" and 280 grit for "fine". There doesn't seem to be a specific grit noted on the stones or packaging for oilstones, and just using "fine" or "medium" terms to describe the abrasiveness seems to be the norm. However you can get more info if you search the web for woodworking, sharpening etc.

I don't know "Why". But that's not the right question. The right question is "What are the grit #s?", and the answer is 2x 320 grit sheets, 1x 400 grit sheet, 1x 600 grit sheet and 1x 800 grit sheet.
