Review on Poliwell 3 Inch Sanding Discs - Premium Variety 40-1000 Grit, for Wet & Dry Sanding 🪚 - Pack of 100 - Hook & Loop - Ideal for DA Sanders, Drills, Woodworking, and Automotive by Talapon Blackburn

This is a very complete set of wet/dry discs including a 3" velcro mount for your 1/4" angle grinder. The set contains 10 discs of each size, from a coarse 40 grit to almost smooth 1000 grit grinding discs. All other included grit sizes are spaced appropriately to suit virtually any grinding need from coarse to very fine. I've only used them for wet sanding and they worked great. When the disc was almost worn out, it was easy to remove it from the mandrel and put the new disc back in. Two flexible sponge wheels are also included for sanding contoured surfaces. Poliwell put together a good set at a good price. I just want the included 1/4" mandrel to actually be .250, it's a bit smaller and I have to tighten my 1/4" collet to make the mandrel hold. It has been my experience in the past that I could not tighten the collet enough to keep the mandrel from slipping once the shank had worn a bit. This is my only complaint and I'm finding this to be more common with tools advertised as having 1/4" collets. The case pictured is not included.
