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.

Actually, they sent me the cordless as a substitution when they were out of this one. Love it! works great! Sharpen all my tungsten effortlessly (well, you do have to change collets) , blunts the tip, cuts off contaminated ends when you dip.

What I ordered was the "Corded Sharpie DX Tungsten Grinder" - what they sent me was the "Cordless Sharpie" - turns out, the cordless version works great and I guess I'm glad they sent it by mistake. The thing puts a very nice point on the tungsten and is consistent. The fact that it's cordless really makes it super convenient, more so than I originally thought.

This tool seems well made. I've only sharpened four tungstens thus far, but it did so quickly and consistently.
