4.5" x 7/8" Premium High Density Jumbo Zirconia Type 29 Flap Disc 40 Grit - 10 Pack
Brand: Benchmark Abrasives

Flap discs are used in heavy stock removal, often weld removal. They outperform Resin Fiber Discs due to their increased lifetime and last twice as long as Aluminum Oxide discs. To achieve a finish equivalent to a Resin Fiber Disc, always use a flap disc one grit coarser. e.g. If the operator is running a 60 grit Resin Fiber Disc, try a 40 grit flap disc. This 40 grit flap disc is made with Zirconia Alumina grain, which is ideal for stainless steel and metal applications while still working well with non-ferrous applications. The Type 29 angled face allows for 90% of the abrasive material to be in contact with work surface, yielding maximal grinding surface area for greater ease, effectiveness and speed. We use a high quality backing plate to help absorb vibration. Specific suited applications include: weld blending, removing weld slag, deburring, edge blending, surface conditioning and general metal fabrication. 'Jumbo' or 'High Density' flap discs usually contain 30-60% more surface area for grinding.
