1. Precise Diamond Ground Taper:
Sharpie grinders deliver quick and consistent adjustable grind angle from 15° -to- 45° 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.
2. 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.
3. 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.

Man I love this thing already. I have a small shop in my garage and the bench grinder I have only has one wheel on it. I’ve used this thing to sharpen my electrodes and it makes it a more consistent taper and doesn’t leave the grind marks that happen with the bench grinder. I wish I had more TIG Work to use it more. For now it’s just keeping my skills up.

Decent little grinder, guess I will see how long it holds up. Would of given it 5 stars but since I haven't had it long enough to see the reliability that's why I gave it 4 stars.

cool little grinder faster and better then a bench grinder doesnt heat up the tungsten while grinding a big plus no burnt finger tips and its by far the least expensive of all the tungsten grinders out their thank you arc-zone

I just received this Sharpie and think it's just great. It will sharpen the tungsten fast and accurately every time. No more contaminated tungsten's and no need to have a dedicated bench grinder anymore. This unit will cut the contaminated tungsten and sharpen it fast. Spending the extra $'s for the Deluxe model was a wise choice as well with the extra grinding wheel and storage case. The unit is built very well and runs very smooth plus it has a variable speed adjustment and a trigger lock.If your trying to obtain the perfect Tig weld this is a must have and this is absolutely the right place to buy it.
