The Diablo DCD068100H01W 6-7/8 in. 100 Grit Sanding Disc with Hook and Lock Backing for ALTO Sanders is a sanding disc made for surface preparation and general sanding work. This is a sanding disc designed for material removal and surface smoothing on compatible ALTO sanders. Model Number: DCD068100H01W. If you need a replacement abrasive that matches the tool correctly and changes out quickly, this is the kind of accessory that matters.

The key spec here is the combination of disc size, grit, and backing style. At 6-7/8 inches, this disc is built for sanders that require that exact diameter. The 100 grit abrasive sits in a useful middle ground for users who want a disc that can handle prep work, knock down roughness, and move a surface toward a more finished state without being overly aggressive.

The hook and lock backing is the practical feature most users will care about day to day. It gives you a quick attachment method that makes grit changes easier during multi-step sanding. On the job, that means less downtime when you need to swap a worn disc or move to a different grit for the next pass.

This Diablo sanding disc is a straightforward accessory purchase, but fit is everything with discs like this. The 6-7/8 inch size and ALTO sander compatibility are what make it relevant. If your sander takes this format, you get the proper contact pattern and a disc that is designed to work with the pad the way it should.

For buyers comparing sanding accessories, this is not about extra bells and whistles. It is about getting the right abrasive size, the right grit for general prep, and a backing system that lets you keep working instead of fighting with disc changes. That is what makes a simple sanding disc either useful or a waste of time.

Who should buy it? Anyone running a compatible ALTO sander and looking for a 100 grit replacement disc for surface prep, smoothing, or intermediate sanding steps. It makes the most sense for users who already know their sander's required disc size and want a no-nonsense hook and lock abrasive from Diablo.
