Full Sand Diamond Wheels Tungsten Electrode Sharpener Blades Replacement Cutting Wheels Tig Welding Discs 10pcs 25mm 0.5mm w/ 2 CNC Connecting Rods Compatible with Dremel Rotary Tools

Works perfectly in my tungsten grinder and a very affordable price. If you just let the wheel do the work and you don't jam the tungsten in the sharpener they last a long time. Easy to use and creates the perfect surface you want on a tungsten electrode.

These work well for grinding tungsten electrodes (for welding). I also used one for cutting plastic headlight lenses with good results.

These work great ,cuts quickly

I'm using these to sharpen tungsten electrodes for tig welding. They do a great job for that.

What kind of lunatic tries to cut through a half-inch hardened steel rod with a hand-held rotary tool? (I raise my hand ... ) Without going into too much detail, let's just say I spent a full day crouched over a hole in the ground, grinding away with these little wheels. I wore out most of the discs, my back and my patience — but in the end, the rod surrendered. The discs that remain have proved valuable for a variety of cutting & polishing chores, and I'd recommend them for medium-duty chores around the house.
