SCOTTCHEN Diamond Flat Lap Wheel 6" x 1/2" Arbor Grinding Sanding Disc Lapping Polishing Disc-80 Grit

I bought three of these to sharpen chisels, hand planes, and knives on my drill press. They work great. They are very high quality and look like they will last a long time if used properly. I'm going to purchase a courser grit for axes and hatchets.

Funciona muy bien

I use this lap after my 60 grit course lap. It works very well and is holding up great. I'm not using a backer plate as this sits flush against my wheel but if I didn't have a backing support I would use some kind of plate backer just for support. Diamond coverage is excellent and break in was easy with very little loose material coming off.

These topper laps work well for me. I would avoid using these past about 800 grit however. The grit consistency is not very good and in the high grits I always have scratching like a lower grit which makes the higher grit pointless. If you have used more quality laps, you might find the grit level to be a bit off. For example I have an 800 grit lap that cuts more like a 400-600 if compared to a Crystalite lap. I have a 3000 grit lap that leaves random scratches like a 400-600 grit but it cuts as fast as a 3000 grit so that lap is junk and I don't use it. I have a 1000 and a 1200 that have similar issues. I recommend these laps to help save money as long as you stay under 1000 grit.

I wish it to be thicker and sturdy.
