Diablo DCD068080H01W 6-7/8 in. 80 Grit Sanding Disc with Hook and Lock is a sanding disc made for ALTO sanders and sold as a single-disc accessory. This is a sanding disc designed for moderate stock removal and intermediate surface preparation. Model Number: DCD068080H01W. If you need a replacement disc for a 6-7/8 inch ALTO orbital sander and want a medium grit that can handle prep work before finish coats, this is the right kind of accessory.

The big story here is fit and purpose. This disc is sized specifically for 6-7/8 inch ALTO sanders, so you are not trying to make a standard round disc work on a machine it was not meant for. The 80 grit rating puts it in the useful middle ground for taking down surface material, cleaning up rougher stock, and getting wood ready for the next sanding step or a top coat prep stage.

Diablo lists this as a premium ceramic blended sanding disc, and the supporting product data also calls out a premium zirconium blend. What matters on the job is that the abrasive is built for material removal and longer sanding life than bargain paper discs that quit early. When you are working larger surface areas, disc life matters because every change slows you down.

The hook and lock backing is another practical feature, not just a line on a spec sheet. It gives you repeated attachment and removal without fighting adhesive residue or dealing with discs that shift around once they heat up. For anyone doing floor sanding or broad surface prep, quick swaps keep you moving and make it easier to step through grit changes as the surface gets closer to finish-ready.

Diablo also includes its Clog-SHIELD coating and ENDURA-BOND resin system in the product details. In plain terms, that means the disc is built to resist loading and hold the abrasive to the paper backing under harder use. Less clogging means the disc keeps cutting instead of skating, and a stronger grit-to-backing bond means you get more usable life before the disc is done.

This sanding accessory uses a paper backing and is ideally used with disc and orbital sanders, with ALTO sanders being the intended match. It is commonly used on wood, and supplementary image data indicates it may also be used on plastics and metal, but the strongest source-backed material callout is wood. For buyers who want a direct-fit sanding disc for an ALTO floor sanding setup, that is the key compatibility point to pay attention to.

Who should buy it? This is a good fit for flooring contractors, remodelers, finish carpenters handling surface prep, and serious DIY users maintaining or running an ALTO sander. If your work starts with rougher material, old finish cleanup, or prep before coating, the 80 grit medium sanding grade makes sense. If you need final finish sanding, you would step finer than this.
