Walter 06B454 ENDURO-FLEX Abrasive Flap Disc - [Pack of 10] 40 Grit, 4-1/2 in. Finishing Disc with ECO-TRIM Backing. Blending Discs

Some of the best quality discs for the money. Walter has knocked it out of the park in designing these flap discs. While I prefer the spin on version the amazon price for these was much better than the local welding supplier. They last forever and take down material quickly. You won’t be disappointed

These work very well for sharpening lawn mower blades. They are not so aggressive that they get the blade hot but instead allow a controlled removal of material.

If you do the math you realize how pricey these are. But they seem to me to be quite durable and worth the spend.

I won’t do ANY grinding without these discs. They’re magic! Well worth what you pay for them

Outstanding product been using for 6 months and I've only used one, most of the other grinding wheels I've used would have wore out 3 times by now

Great product well made and worth the money

Excellent product. Takes a beating and still out lasted the big box store flavors.

Super fast shipping great product

Love everything but the price, Shipping was fast and it was exactly as ordered.

Fast delivery, good stuff!

Walter top quality, worth the money because these work faster, and last longer than all the others. No one wants to grind any longer than you have to so buying quality abrasives is money well spent

They are of good quality and last a long time.
