At Arc-Zone.com we offer a free, downloadable PDF on the correct way to grind tungsten in our Welding Library, but here’s some quick tips from the Weldcraft® catalog to get you started:

• Grind your tungsten electrode Longitudinally, not radially
• Prepare a tip flat
• Use a dedicated wheel for grinding tungsten

We also recommend a dedicated tungsten grinder for TIG / GTAW welding and Plasma Arc Welding (PAW) applications.  Arc-Zone carries a full line from the handy, inexpensive Sharpie(TM) hand-held tungsten sharpening tool to the more rugged, precise DGP with a fully integrated vacuum system.
