Product Description
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.

    5Don't buy these if you think you'll always get what you pay for!
    By Amazon Customer
    After using a variety of locally sourced flap wheels for the past few years, I finally decided to try these out. If you're a firm believer in always getting what you pay for, these aren't for you... after paying between $5 and $20 per wheel locally from places like home depot, Lowe's, tractor supply, airgas, and other welding suppliers, I can honestly say that these are a much better value than anything else I've ever tried. I've only used a couple so far, but I can confidently say that these have outperformed what I used to consider a fairly long-lasting wheel (ones that cost $14-15 EACH!) and I am VERY pleased with my decision to try these- I'll definitely be buying more!

    For anyone who is wondering... I am NOT associated with the seller in any way, shape, or form. They have not bribed me to write a positive review. I am just a regular guy who is just really pleased with a quality product at a reasonable price!

    5Good quality flap disc
    By Willie
    Had a chance to use these on a steel project - works well.They are holding up and cut as expected .Nice to have a box of 10 , as I would end up going to welding supply to get a couple at a time. I would buy again , quick ship - no complaints .

    4These Work faster than the 80 grit discs, last longer, and are cheaper than the Big Box Stores
    By Jeffrey Roberts
    These work great. I had been using the Neiko 80 grit discs for removing mill scale from my steel welding project, which worked fine, but these are thicker and work faster, as they are more aggressive, but do not leave a rough finish as I initially expected them to. Price can't be beat compared to the Big Box Stores.
