Grey wheels for most steels and cast iron, Green wheels for roughing tungsten carbide then diamond wheels to finish. White wheels are usually only used on grinding machines, surface grinding. Bert

thanks for the info - ive no idea what they are, theres no specs/sticker on them. they were supplied with the grinder. il take some photos shortly :thumbup:

Been wondering this myself, my grinding wheels at home disappear vs the ones in work all I really use it for is tungsten, think it's 80 grit

Sounds like your problem is you have sillicon carbide wheels fitted? These are for grinding carbide and hard materials, which means they have a soft binder, and are very dusty. They will work on soft materials but make a large mess, as you found out. Alumina wheels will grind all the materials...

Its the lump you sent. The triangular shape is the main problem, couldnt grip it easily to get tools on it. I should have another go..

they get a bit pricey too , a flat heel dolly in tungsten would be a mighty thing to own ,,,

I've turned a few lumps of tungsten into bucking bars. It's a bloody nuisance. Grinding discs hardly touch it, carbide and indeed HSS milled it ok though.. Reckon the bandsaw would chop it ok if I had to do more.

They are based on a bench grinder but modified with a diamond wheel and guides for accurately grinding tig electrode tips.

2% lanthanted is the best all rounder. Purple are supposed to be good and I have a pack, not tried yet. Unlikely I will tell the difference between them. Thorated are often said as best but the downside of being radioactive and a bigger hazard for grinding is not worth it. I cant tell the...

Would you share the STEP of the modded one please, you handsome fellow?

Two of these: for grinding tungsten points on a Dremel with one of these diamond discs. It uses a standard collet so copes with different tungsten sizes (although I pretty much only use 2.4 mm ones to be honest). Looks like this on the Dremel: The first one I printed was from thingiverse...

Im not sure what grade but it came from a 125cc bike rear calliper mount. I dipped all of my scrap in NaOH to remove the worst of the oxides. The calliper mount came out silvery where as all my engine scrap turned a nasty black, I assume from sillicon. Vents, the first one I did add a few small...

I I do that too, got an old Bosch 10v driver I put a cheap eBay hex shank Chuck into. Works a treat and doesn't spin crazy fast as its a screwdriver.

I shove the tungsten's in my battery drill , sharpen them both ends On the bench grinder I use the green wheel or an angle grinder face grinding disc I tend to use the aluminium oxide " Parkside belt sander " a lot to sharpen them too , again with the tungsten in a running battery drill...

Resin diamond wheels go to much finger grits which may be better. Not needed for tungsten but they last well enough. 4-6" ones are quite cheap on ebay. I made up a small dc motor powered grinder for it. I'd say 8" is too big but wont do any harm.. just a waste Id use an alumina wheel flon the 8"...

My 8" grinder wheel needs replacing, what's the best wheel or disc I can replace it with for grinding my tungsten?

All dedicated stuff used on ali, grinding discs, wire wheels, even got a dedicated mini bench grinder for sharpening tungsten for ali only. i have wondered if its the welder having a funny moment, tis only an Rtech thing, but all i could stretch to at the time of buying.

Just a random question (And for a change, it's a pretty short one ! :D). As far as I remember from science class, Tungsten is meant to be hard as nails, so would TIG torch electrodes hold a point better for scratching lines in rusty steel than tool steel scribes? I've never owned a TIG welder...

Tig in a hole is difficult to start! Enjoyed that, I am hoping I got enough heat in at the bottom. I also welded up the spanner, less successfull. I used the amazon foot switch and the original torch with a 3.2mm tungsten as I wanted to try it, amps too high, made a melty mess. It will need...

This times a million. Everyone should put a cheap diamond wheel on, they are so superior to a standard abrasive it shouldn't be a question unless you cant spare half a bench grinder.
