Precise Diamond Ground Tungsten:
Sharpie grinders deliver quick and consistent electrode grinds for snappy arc starts, better puddle control and improved weld quality. The double-sided diamond wheel easily grinds tungsten electrode sizes, .040"**, 1/16", 3/32" and 1/8" (1.0mm, 1.6mm, 2.4mm and 3.2mm). **Note: .040" (1.0mm) collet sold separately.

High Quality Tool:
You are investing in a quality product that will deliver years of service. Each Sharpie is built to demanding specifications.  The majority of the machined parts are made in the USA!

Tip Flat Option:
Tungsten electrodes ground to a sharp point are proven to burn off and cause inclusions in your weld. By Removing the point & adding a tip flat, you get better arc starts, longer electrode tip life & reduced weld contamination.

Cut-Off/Score Option:
The built-in cut-off or scoring option allows you to cut & remove only contaminated portions of the electrode. No more bending or breaking electrodes which causes splintering of the tungsten, reducing electrode performance.

Safe & Easy To Use:
Set your machine up for the job at hand & grind electrodes in the shop or in the field. Enclosed grinding wheel eliminates safety issues common with "side" or "wheel" grinders which can grab the electrode and shoot it back at the operator.

Save Time & Money:
Diamond ground electrodes reduce tungsten consumption and waste. Stop wearing out belts on your sander & grinding deep grooves in your bench grinder wheels. Your shop will be cleaner, safer and more productive. The reversible long-life diamond wheel means low replacement part costs.

Weld Like A Pro Tip
Frequently re-grinding worn electrode tips improves weld quality & lowers tungsten usage. Waiting until the tip is completely eroded or contaminated, requires grinding off more tungsten material, resulting in higher tungsten usage, costing you time & money.


Minimum Tungsten Grind Length 1-1/4” (31.7mm)
Adjustable Grind Angle From 15° - 45°

Overall tool is great. 3/32 collet is a little lose would prefer a nice snug fit when grinding to ensure full 360° consistency. Not sure on fitment of others at this time.

Perfect grinder to have in the shop. Thought the head only and attached it to a rotary tool I had laying around the shop being useless. Not it's being used regularly.

I was led to believe this device would fit a Milwaukee M12 die grinder. It doesn’t.

Works pretty good, however leaves a rough finish on the tungsten.

I also found that it is not that accurate. Regardless to where the angle is set, the operator has to control the pressure. A bit too much pressure you will get a much more shallow angle than desired. It's not just stick it in and it comes out perfect, as I would have hoped.

It is handy, and if you are welding on site nice and light to carry with. It's also compatible with all my Milwaukee batteries. The welds are just as good as using a tungsten sharpened on my diamond bench grinder setup.

I bought it just for the portability, and for that it does the job I need it to do, but still room for improvement.
