Good disc for the price. The thickness of material on the disc is much better than most other disc out there .

Still working on my 1963 aluminum 36 foot Chris Craft Roamer. 20 years ago I replaced the cheesy plywood cockpit paneling with 1/8" aluminum. Water had ingressed between that and the teak floor trim causing the catylized paint (Interlux Perfection) to blister and peel. I used a #120 flap disc to feather a clean shiny edge through the failure, up 2 inches into the good paint. After seeing the results, I decided to take some 180 hook and loop and sand the entire panel for repriming and repaint. The results turned out to be nothing less than magnificent. The whole job barely bothered the flap disc (still like new!) and about 1-1/2 discs worth of 180 for a perfect sanded primer job. Baby a$$ smooth! Im a firm believer in your products and refer you often. Bill in Two Rivers, Wi.

Great product! Bought the T27 pack. Wish I could’ve just bought a T 29 and a T 27 pack and had shipped together at the same time.

Awesome made and very tough flap disc for grinding the longest lasting I have ever used. Benchmark is all I will use from now on. I’m very impressed and that’s hard to do now days!

I ordered these flap discs right around Christmas. They arrived promptly and I was able to use one on a project on New Years Day where I am learning how to weld. The disc performed incredibly well with cleaning up the material and hogging off material. I am very pleased with the quality and value of these discs.

I had my doubts as to whether I'd ever actually see these, as the deal is so good I can't figure out how BA is making any money, but I received the flap disks quickly and they are excellent quality. I received ten disks for the price of two and didn't have to drive 20 miles to a certain discount tool store to get them. The disks are thick, so should last a good long time.

I bought these on a whim as they were offered at a great price. Literally the day they arrived I needed to hog off about 1/4" x 1. 5" x 4' of fir wood from the face of a 2" x 6" piece of framing on the bottom of a swinging 6" thich panel. I couldn't reach it with a circular saw blade. Normally I'd use a hand plane, but I needed this done quick and I didn't care about the resulting finish. A 40 grit disk on my grinder had the job done in less than 3 minutes, and it didn't even wear out the disk. Extremely high quality abrasive on a solid backing, this is a quality product.

Product description
Product Specification
4-1/2" X 7/8" T29 ZIRCONIA HIGH DENSITY FLAP DISC - MIXED GRIT 10 PACK (FREEMIX)
Our mixed pack is a great opportunity for you to test our range of grits at an affordable price!
4-1/2" x 7/8" T29 (Angled Face) Zirconia High Density Flap Discs are manufactured using European zirconia cloth. The European material is superior due to its uniform particle size and premium blend of ingredients. These discs exceed our other flap discs by packing 40% more abrasives on each snippet than our regular density discs. In addition, all discs are manufactured on computer-controlled machines and subject to numerous tests which ensure high quality and greater safety.
These type 29 flap discs are a versatile product that can be used from aggressive stock removal to surface blending. The layered construction of abrasive flaps on this flap disc will continually expose new grains for longer life and finer finish compared to resin fiber discs. It can be used for heavy material removal on all types of metals.
T29 (angled face) discs are angled up at 15 degrees to provide optimal, ergonomic flap use when grinding down items that are flat surfaces (like bead weld).  For the best solution on non-flat surfaced check out our T27 (flat face) flap discs.
Zirconia grains have a self-sharpening property and stand up to higher heat and pressure than Aluminum Oxide (A/O), thus making Zirconia the go-to option, providing excellent stock removal that gives you more bang for your buck.

Safety Tips & Techniques:
·This mix is known as our FREEMIX.  Use the code FREEMIX to get 1 of these fantastic mixes for free (+ shipping, unless your order value total is $50+)
·For less stock removal try using a lighter touch or a feathered approach to your grinding.  Flap discs are like grinding wheels with power steering!
·Always wear proper PPE to include (but not limited to) safety glasses, hearing protection, respirator, and hand protection.  Keep all guards in place on your machine.
