Benchmark Abrasives 5" Premium Ceramic Resin Fiber Grinding Sanding Discs with Double Resin Bond Technology for Metals, Wood, Fiberglass, 7/8" Arbor, Angle Grinder Discs (25 Pack) - 36 Grit

I buy these for my shop. I've tried every abrasive on the market for 25yrs and these are by no means the best, but they are the best for the money. They can be used at all stages of life, and I go through about 100 per month in comparison to next closest competitor @ 250 per month. They work harder longer. we do a substantial amount of grinding down welds and blending on cold rolled mild steel and aluminum.

On first impression these seem similar to most fiber discs. The discs where curled up a little right out of the box, so to mount one on my grinder I needed to flex it back in shape. The base material seems to be very brittle, but I'm willing to try them to see how long they last.

Well-made and durable. Should be kept in a warm environment when not in use - when kept outside the adhesive will warp on the disc (as is standard for these types of discs). Used on mild steel to great effect.

this cut steel like butter

This is a great set of resin fiber discs. They are very strong and thick, making for longevity and durability. The 25 pack is perfect, and is a good value for how many you get. This set will last me for a while.

I am a welder/fabricator and figured I would try these out. Horrible product hands down. Some discs were bubbled up and the quality control sucks. Some were red and some looked like the were 1/2 ceramic and the other 1/2 of the same disc. Looked like it was the alum crap. Save urself and buy can discs or u can go with black hawk. Vsm is the best out there

I bought these to strip old paint off a boat I'm rebuilding. They were a better price and lasted a lot longer than the "name brand" ones from lowes.Definitely a great deal. I will be buying more

For the price these are decent, they keep a little bit of a bend in them which isn't the end of the world for me, but if you need them to be flat, keep that in mind. Until next time, stay healthy and happy shopping!
