For those of you who don't know which grit to purchase, we present to you the Flap Disc Application Chart. The chart above is a great reference for first time buyers who aren't sure which grit to purchase. Make sure you choose the right Benchmark flap disc for the job at hand! Here is a breakdown different grains we offer:
Ceramic Alumina (Red) â The latest innovation in abrasives, this grain micro fractures to allow a continuous supply of the sharpest cutting edges. These discs provide the fastest cut as well as the best utilization of the entire grain for the longest life, especially on stainless steel and high alloy materials.
Zirconia Alumina (Blue) â An excellent blend of zirconia and aluminum oxide grain which provides a very good cut rate to cost ratio. This is a very good choice on carbon/mild steel applications.
Aluminum Oxide (Brown) â The original metalworking abrasive, this product is recommended for smaller jobs where a consistent, low cost product is needed.
