Item Details

  • Designed for use with a right angle grinder, this Merit ZA coarse grit arbor thread fiberglass heavy duty conical flap disc delivers a fast and efficient cut rate thanks to its zirconia alumina abrasive. The angled polyester and cotton flaps provide excellent surface contact that makes it easy to remove stock from contour and edges and get the job done quickly. Great for coarse grit blending and deburring on various metals, this product is comfortable to use due to the strong, lightweight, fiberglass and resin backing which absorbs vibration.


  • The innovative design of Merit's advanced PowerFlex Flap discs allows you to grind and finish in only one smooth operation, saving both time and money
  • With the two-in-one PowerFlex disc there's no need to change tools, no need for additional processes and no need for a backing pad
  • Also grind cooler without bluing and last up to 15 times longer than resin fiber discs
  • They are safe, quiet, and easy to control for rapid stock removal, consistent finishes and longer disc life
  • The layered abrasive flaps on the flap disc are designed to wear away evenly
  • Produce a high-quality, consistent finish on steels, metals, and other exotic materials
  • The added abrasive gives a cushion to the product which provides a quick grind with less heat to produce a higher quality finish
