Full Sand Diamond Wheels 3mirrors Tungsten Electrode Sharpener Blades Replacement Cutting Wheels Tig Welding Discs 10pcs 25mm 0.5mm w/ 2 CNC Connecting Rods Compatible with Dremel Rotary Tools

The discs work well with the 3 Mirrors tungsten electrode sharpener and are able to quickly sharpen a new tungsten without any noticeable wear. Its not only faster than my normal bench grinder, it also avoids me from wearing a groove into my bench grinder stone wheel while sharpening tungstens. These discs are great value for money and well worth their cost.

Great quality and easy to use. I’m grinding tungsten for TIG welding and it is working quite well.

They are exactly what I needed. Tho I was missing the small screws I was lucky to have a few that would fit. Over not a bad buy.

so far so good

Work as expected.

Works great, greatly reduces the time to point the tungsten for TIG welding. very much worth the money.

These are awesome diamond wheels. They are very straight and true, and have held up really well. I use a little bit of dressing on them and they have gone through a lot of material and still working well!

Seems to work okay.

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

Most buyers will likely think these diamond disks look fragile becuase of their thinness, and they would be correct in thinking that if you apply too much pressure to the face OR to the perimeter edge, they will distort out of flatness and also wear the center hole to the point that they will sotp rotating even though their mounting shaft is still rotating. BUT . . .If you are applying that much pressure to sharpen a TIG Tungsten electrode, you are not using them correctly. It does NOT take much pressure to properly sharpen the electrode - you instead let the diamond grit do the work! Mount the diamond wheel snugly onto the shaft, apply only moderate pressure, rotate the shaft continuously in yoru fingers, and patiently let the diamond grit do the shaping of the electrode.Also, do NOT try to cut the electrode shorter by holding it against the rim of the diamond wheel. This creates too much force for the very small bearing surface bewteen the motuning screw and the diamond wheel, and so causes the wheel to "slip" on the shaft. THis enlarges the mounting hole in the wheel until it no longer will rotate proeprly with the shaft. The wheel is then ruined and needs to be discarded.The RIGHT way to shorten the electrode (to cut off any deposits on and near the end of the electrode), is to grind a "V" groove around the entire circumference of the electrode, just above the deposits, and then SNAP the electrode. Then, use the diamond wheel to grind the cut end to the desired angular point.This process has been working well for me.

bought this with high expectations the cover will not go on with orings even with oring lube in place. had to make special spacer too fit my dremal tool works good at sharpening tungstens price about 50% too high

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

Work just ok ,wont last long on tungsten sharpening but price is cheap
