JINGLING 4" inch 100mm Diamond Flat Lap Discs Grinding Disk Grit 120 Coarse

Worked as expected.

I simply use this a speedy way to prep tungsten electrodes - the 320 grit is just right.

I got this to sharpen my tungsten on my tig welder. I am not a good tig welder yet so I am constantly buggering up my tungsten. Works great so far. Have ground a full tungsten stick to almost gone 1/4” at a time. Disc seems to be holding up, no signs of wear.It would be nice if the edge had diamonds, it is smooth so when I really get globbed up I have to grind it square all the way past the contamination which is slow. No side cutters to score and snap but it sharpens very nice on the 320 grit

Work

Works great and hasn’t worn out yet. Used it allot welding stainless

sharpens carbide like butter. what else can be said. i made a solid aluminum back plate so it wouldnt flex.

I sharpened 4 saw blades with it and already saved as much as a paid for it

This wheel is so out of round it will more then likely take the bearout of my angle grinder if i keep using it. Cheap trash.
