Sharpie DX™ Head Only DIY Tungsten Grinder Kit


The Sharpie DX™ tungsten electrode grinding head kit (motor sold separately). Tungsten Grinding Head Kit is designed to fit on most die grinder type motors that have a 3/4" x 12 threaded collar.  We recommend the Milwaukee M12 cordless rotary tool (2460-21), or the Black & Decker RTX corded model (A-PTG-001) but there are many other suitable alternatives, including, but not limited to:

  • Milwaukee M12 Rotary Tool (2460-21)
  • Black & Decker RTX (A-PTG-001)
  • TECCPO Upgraded Rotary Tool

The Sharpie DX™ has an adjustable grind angle from 15° -to- 45° for virtually any TIG welding application.  The engineered head design allows for grinding, cutting, and adding a tip flat.  The Head Kit features on-board storage of the 1/16" (1.0mm), 3/32" (2.4mm), & 1/8" (3.2mm) collets (0.040" (1.0mm) collet sold separately).

Kit Includes:

  • DX Grinder (15°-45° Adjustable Grind Angle)
  • 1/16" (1.6mm) Collet
  • 3/32" (2.4mm) Collet
  • 1/8" (3.2mm) Collet
  • Medium Grit - A-PTG-002A Wheel


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, we use only the finest globally sourced motors & 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°
  • Recommended no Load RPM: 5,000-32,000
