Why are they better? Other than some are bigger.


DMT uses less abrasive material so they can sell their product cheaper. They use a metal mesh to surround the spots of diamonds and falsely claim that this helps to prevent clogging. What the metal mesh design really does is make the job harder and take longer.

I do not like the ones with holes. They do not work well to put a sharp edge on a small thing as a carbide insert.

Clogging is not really a problem. If you use water with some dish detergent you do not get clogging. If you use it without anything to float the metal bits away, then using a light wire brush or a regular tooth brush and some soapy water will unclog it.
