Review on 🔹 MoArmor 545 Diamond Cutting Wheel Set (22mm) - 10pcs with 402 Mandrel (3mm) - 2pcs and Screwdriver for Rotary Tool by Mike Barnes

I only bought these to cut 1/4" pure tungsten rods so my comments will be limited to that purpose. The product is described as a "diamond cutting wheel" but when If you're thinking of using it like a small circular saw to cut a slot in a tungsten rod, forget it because the diamond bits are only on the surfaces of the wheel and the edge of the wheel, not deep into the wheel base material using the blade like a small circular saw will chip off the diamond bits fairly quickly. However, the diamond coated surface grinds tungsten excellently. A disc I used seems to be just as good as when I first started. So now I cut the tungsten rod and get flat, clean ends, I put the rod in a vise, use a hammer to break off a piece a bit longer than I would like then clamp the piece in a vise and use the disc to sharpen the r marked end until it is flat and clean. Ugly I know, but it works. I would definitely buy this product again but I doubt I'll need it as I haven't even worn it on any of the 20 sides of the 10 wheels I received.
