PRODUCT FAQ

  1. What grit is the 3M™ Hookit™ Blue Abrasive Disc 36531, and what does "40E" mean?

    Great question! The "40E" refers to a coarse 40-grit abrasive, which means this disc is perfect for aggressive sanding or fast material removal.

  2. Does the disc have any holes for dust extraction?

    This version does not have holes; it's a solid (no-hole) disc that's designed for use with compatible backup pads on your sander!

  3. How many discs come in each box and how are they packed?

    Each carton contains 50 discs, and there are 4 cartons in every case—so that's a total of 200 discs per full case!

  4. What surfaces or materials can I use this abrasive disc on?

    Absolutely! These Hookit™ Blue Discs work great for stripping paint, shaping body filler, or sanding bare metal—they’re ideal for tough jobs in auto body repair.
