DGP & Piranha III Coarse Diamond Grinding Wheel. 6" (152.4mm) 150 Grit, Single Sided for Piranha 3 and DGP Style Tungsten Grinders. Highest-Quality Wheel Available. -- Made in U.S.A. --
Note: 300 Grit wheels come standard on DGP Tungsten Grinders. A coarse grit wheel (150) delivers a faster grind and a rougher finish. This may be desirable for 1/8” (3.2mm) or larger tungsten electrodes.
A fine grit wheel (600) delivers a near polished finish and is preferred for small diameter tungsten electrodes.
