Since we introduced the Sharpie™ tungsten electrode sharpener back in 2000 (that’s 15 years ago!) it has remained one of our most popular products.
Not only is it a cool tool to have in your shop, with a dedicated tungsten grinder you can improve the quality of your TIG welds and lower your tungsten usage.
The Sharpie™ tungsten grinder is a hand-held tool that preps tungsten electrode sizes .040″, 1/16″, 3/32″ and 1/8″ (1.0mm, 1.6mm, 2.4mm and 3.2mm) quickly, easily and consistently. You can sharpen an electrode, and with the Deluxe model you can set the angle of the point, and repeat it over and over again. The standard model has a pre-set grind angle that is good for most welding applications.
The Sharpie ships with a long-life double-sided diamond grinding wheel and produces longitudinal grinds for consistent welds, deeper penetration and less re-work. You can also use it to to produce a tip flat–tungsten electrodes ground to a pointed tip can burn off and contaminate your weld puddle.
With the built-in cut-off option, you can remove only the contaminated portions of the electrode. No more breaking electrodes which causes splintering of the tungsten, reducing electrode performance.
The PRO Kit is the way to go if you want to make sure you’ve got all the accessories you’ll need in one sturdy kit box. The Sharpie™ Weld Like a Pro Kit Includes our most popular accessory items. You get the .040″ (1.0mm) collet and a replacement double-sided diamond grinding wheel, for just $50.00–saving 25% over the price you’d pay if you purchased each of these extras separately. You also get the industry leading technical guides “How-to-Select Tungsten Electrodes” and “How-to-Grind Tungsten Electrodes” along with the complete operations guide with all replacement parts listed for your convenience.
