What is Avos?
I would like to get away from flap disks as seems like you throwaway more then you use.
I would like to go back to fiber discs w combi lock. What one do you prefer in 60-80 grit?
I sympathize with the frustration of flap discs, knowing you are throwing away material that SHOULD be usable. Almost never do I use a flap disc ‘down to the nub’. 97% of the time, they get glazed over well before they are worn down to the point of unusability.
So I tried switching over to fiber discs, as one of my friends swears by them. He uses them all the time. I bought a couple of packs (HoboFreight) and went through them, but of course, you use them differently, so there is a learning curve, and while I do find them useful for some things, I just cannot get away from the utility I find in flap discs for certain things. Blending corners and such. But fiber discs are great in their own way, as well, for certain things, especially trying to maintain flat surfaces and sharp(er) edges, etc.
I do still find myself using flap discs more, though.
I just picked up a bunch of stuff, in looking through the results, I felt like the Benchmark Abrasives stuff performed well - but then when @Fireball_Jason put out his conclusion video, Benchmark didn’t even warrant a mention, so I was a little confused. Other brands, which I had not thought to be impressive in watching the videos he seemed much more keen on. Another reason I will be glad to get the book when it comes in - honestly, trying to interpret and remember all the data and performance from 48 different products is kind of mind-exploding, and now I’m second-guessing myself and hoping I didn’t ‘blow’ a couple hundred bucks on sub-par stuff. lol
I know, we will always second-guess, as with consumables, you are always always always looking for ‘the best deal’ to maximize performance per dollar.
But I did pick up a mix of T27, T29 various grits (more of the coarser stuff for my personal use case), a bunch of cutting discs and a 25-pack of fiber discs as well - ceramic this time.
I use Benchmark and feel there a good value. I would use there fiber discs but I want the combi lock so there is no nut to run into the work.
@Fireball_Jason - is there a way, a method or a plan to be able to incorporate the new information from the new technique you posted about today (here’s the video) to ‘revive’ partially-used and glazed flap discs and get more life and functionality out of them?
I realize your current flap disc testing methodology is very time intensive and requires a lot of video editing and materials, etc. But I have to wonder about how this technique of ‘revival’ might affect results? PARTICULARLY with flap discs that are thicker, with more abrasive material available for reviving/resurfacing multiple times, perhaps?
For instance, something like the SAIT Encore, at $6+, is only .200 inches thick and I would expect wouldn’t be able to be revived as well, or as many times as some of the other, thicker flap discs, which might benefit quite a lot from multiple revivals, putting them into a category of much better value in spite of a perhaps higher initial purchase price?
What do you think, is this something that can be incorporated into future videos or testing, updated results, or perhaps designing and implementing a whole new testing methodology to be able to exploit this technique to really improve the overall life of a disc?
Its going to be difficult to add a revival technique for every disc. It be hard to keep the conditions the same or optimize the burn off for every disc material.
I do agree - and don’t think I am being flippant in asking you to do more and MORE and MOAR. lol
I just found it interesting, because so many of the discs in the testing had to be stopped or discarded because of glazing, but maybe still had lots of potential life left.
I pretty much have the exact same thoughts on flap discs. For years I have always wondered why people think they’re so great. They are typically expensive, are only good for about only the amount of grit that is exposed (I much prefer a hard disc or fiber disc), they tend to dig when you don’t want them to and make a lot of nasty dust for not doing much work. The best use I have found for them is de-burring edges and I don’t even really like them for that. The next best thing is if you have to round an inside corner.
I know someone has tried this at some point. Watching all the testing made me asking, could cutting fluid extend the life/increase cutting power of the disc?
I believe it just smoke up the room.
Yes. I find this list of tests format to be almost useless. Thx!
Ha a year later reply well i guess that’s what it is avos is a norton product allows you to look through the pad as your grinding very handy for more precision grinding where you are looking to elimate as much undercutting as possible.

I think that is the only use I can say really i find for the flap discs is inside corner radius’ing
