Welding Tips and Tricks

I am thinking of replacing my dedicated wheel on my pedestal grinder for tungsten. I currently use a general purpose wheel and would like to go to a more tungsten friendly wheel, in hopes of getting a better finish on my tungsten. Been using aluminum oxide 5 inch w 1/2 inch arbor.
I cannot spend hundreds on one so looking for advice. Research on internet seems to send you in all directions. Thanks

Look at ceramic discs used for sharpening carbide tools.
Norton BDX is a wheel for that made of silicon carbide.

Not that it is necessary but it is a better disc if you don't want to pony up for a diamond disc.

Cheap route if you can make an adapter...

Since 90% of my welding is 1/16" or 0.040" electrode, I use a diamond wheel in my Dremel . Yes, that is how I roll. Also use it on 3/32" but that takes time.

The Dremel packs easily plus it gets into corners like no other tool. And no oil contamination like with an air die grinder.

I saw this last year no longer have access to a lathe but would be a possibility. Chain saw sharpener blade. Checking Harbor Freight just now and grinding blades for the saw sharpener are wrong arbor size for my need, but are cheap.

If not for ruining the wheel on my Drill Doctor for sharpening my drills that may have worked but put a groove in the stone and it is not much good anymore.

I use this and its about 40 to 60 bucks on ebay. Has a flat diamond surface thats replaceable and a sharp edge up top for cutting tungstens if they get badly fouled.

I just drilled a 1/8 hole up top to act as a guide.

Not sure whats available in the US market but its just a knock off of a drill doctor. For all drill sharpeners they make great tungsten grinders. Gotta be something similar around you at one of the big stores.

We used the green ones for a while. Actual tool sharpening wheels. They work great but the are super soft, so you need to be careful not to grinding a grove in the wheel, spread the grinding across the wheel.

Just saw this wheel being used for tungsten on Weld .com Mr Tig seems to be the ticket out of my budget right now but he said 5000 plus grinds and still like new. https://www.mcmaster.com/#abrasive-grin ... s/=16p88qt. go to glass grinding in left column will get you there is plastic with steel ring covered in carbide dots

You can get a replacement wheel for your drill doctor:

And the diamond grinding disk is for the circular saw blade sharpener (not the chain saw sharpener):

Okay good to know thanks.
