A flap disc packed with twice the abrasive
These high-density Type 29 discs carry roughly double the flap material of a standard disc, in the same fast-cutting ceramic as our Shredder belts. That is where the 5X LIFE rating comes from — more ceramic to wear through, cutting fast and cool on steel and stainless the whole way down.

Questions
Ceramic Shredder flap disc FAQs
Will this fit my grinder?
Any standard 4-1/2″ angle grinder with a 7/8″ arbor. Need threaded? See the 5/8-11 hub version.
What does Type 29 mean?
The face is angled — best for aggressive grinding at 15–25 degrees to the work.
Why high density?
About twice the flap material of a standard disc — more abrasive to wear through before replacement.
Which grit should I start with?
36–40 for heavy weld removal, 60 for general grinding, 80–120 for blending.
Ceramic or zirconia?
Ceramic — it cuts faster and cooler on steel and stainless, and lasts far longer per disc.

Overall rating: 4.8 / 5 from 260 reviews.
We, at Brothers of Steel, use the 36 grit for fast stock/weld removal and the 60 grit for the final polish. They work soo well that we've almost completely removed hard wheels in our polishing processes thus reducing errors and increasing productivity.

The walnut and maple burl in this sandtimer were a breeze to rough sand with my new disc. Watch out wood!

OK, first of all I am not a knife maker. I do metal art! and after 40 years I have found the brand I will stick with. I saw an ad on Instagram and thought yeah right, but gave them a try and they do everything promised and more just wish I had found sooner.

Learning to craft knives from annealed files. Still much to do on this knife project. I love the speed at which these wheels work. This is from a 36 Grit wheel, used on multiple projects still in process and a Farrier's rasp as the substrate

These grinding disks are amazing! They last so much longer than regular disks. They also get into tighter places with their higher profile.

Pleasantly surprised at the quality and performance compared to the usual ceramic discs from Lowe’s. This one is still going strong long after I would have killed the Lowe’s ones. Performance was better with less pressure needed and it seems like a lot less heat generated in 5e metal I was smoothing. I’ll order these again for sure!
These shredded the scale off my knife blank after forging so fast and prevented a wasted belt!
smooth very nice with minimum wear
Great disks! I will be buying more as I am ALWAYS in “Combat against rough metal!” Lol, sorry, I had to say it.
Best option that I have tried so far for removing forge scale. It removed the scale pictured quicker than any other flap disc I that I have tried.
Good belts. The 2x72 ceramics last a LONG time.
Made my first hatchet from h13 steel. Played around on my small belt grinder for hours. Threw a 36 grip flap disk in my Angle Grinder and it chewed through forge scale and smoothed everything out in a few minutes like magic. Unbelievable!!! And that is some hard steel!!! Best thing ever.
Can’t beat these flap discs!

Their good but, I don't know what you're comparing them to when you say 5x the life, that's a bit of a strong statement. They seemed to quit cutting and polishing after about 4 welds, 2" long.
