This 40-grit flap disc improves the working experience by removing the guesswork with its innovative segmented design that delivers transparent line of sight to the work surface while grinding for reduced over-abrasion and maximum efficiency. Along with its segmented design, a special coating reduces heat buildup on the disc compared to traditional flap discs for increased performance and longer life. SIGHTMAX™ flap discs utilize a high-quality zirconium abrasive grain for quick stock removal, and their iron- and sulfur-free construction reduces oxidizable particles left behind on finished surfaces to help prevent rust from forming. A coating slows moisture exposure for extended disc life. The conical 10-degree flap arrangement improves grinding ergonomics for improved tool handling.

The only drawback, the wheel wears down rather fast, when compared to standard flap disks. Can't win them all, but it does work wonderfully.

This is a purposely broken wheel . Do not use ! The structural integrity has been compromised and they are not balanced. They can turn into shrapnel at any minute! Amazon should not be selling this junk

I have already used this on 2 separate occasions and couldn't be happier. I'm just learning other welding techniques and this makes shaving off unneeded welds so much easier. I am definitely going to buy more in the future as well as different grits. Good job whoever came up with this!!!

Being able to see exactly how my finish is turning out. What a simple concept! I let a friend borrow one, and he is a believer. I know when the word gets around, these will be flying off the shelfs.

I use flap wheels for most of my surface removal and welding grinding and these disks are by far the best ever since you can see through the disc as you work!
