We manufacture Porcelain signs, but the metal has to be prepped. We have tried various angle grinders and the DeWalt 11 amp 4.5" with the paddle switch out performs all the Metabos and any other grinder out there.

Do you have a type 1 guard for the DeWalt DWE402 4 1/2 inch grinder?
Robin Datta on Jun 18, 2016
BEST ANSWER: We do not currently carry a Dewalt OEM guard, but Bosch retails a Type 1 guard that may fit. The model number is 18CG-45E. We would advise speaking with Dewalt's technical support for additional information (800-433-9258).
Does this grinder come with the handle, guard and wrench? It is not stated in the description.

BEST ANSWER: Yes, the handle,guard, and wrench are included in model DWE402

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
