Meet the Diablo Sand Demon DND050320H50I 5" Sanding Discs with Connection Pad — a 50-pack built for serious finish work. Featuring 320-grit abrasive with a precision connection pad, these discs are designed to deliver flawless results on wood, metal, plastic, and painted surfaces.

Open-net SandNET technology for cleaner, longer-lasting sanding

Sand Demon discs use SandNET technology — an open-net, clog-resistant design that minimizes dust buildup and heat buildup during use. The result is a more consistent finish, less clogging, and dramatically easier debris management. The open-net structure makes it simple to shake out dust, vacuum, or rinse away particles to restore peak performance.

Washable, reusable, and up to 10x longer life

These discs aren’t one-and-done. They’re washable and reusable, offering up to ten times the life of standard sanding discs under typical workloads. That means fewer interruptions to change media, lower ongoing costs, and more productive sanding sessions. To refresh them between jobs, shake out loose dust, vacuum, or rinse with water and let air dry.

Versatile performance — wet or dry, across materials

The Sand Demon discs excel in both wet and dry sanding, making them a versatile choice for a range of projects. Use them on wood for a silky-smooth finish, on metal for deburring and prep, or on plastic and painted surfaces for controlled material removal and defect-free results. The grit remains consistent, so you’ll get predictable results from material removal to final finishing.

What’s included and compatibility

Includes a 5" disc with a 320-grit abrasive and a connection pad, designed to fit standard sanding systems. The reliable connection pad minimizes vibration for steadier control and a more comfortable sanding experience, helping you achieve uniform results across the workpiece.

Ideal use cases

• Cabinetry, furniture refinishing, and cabinetry updates where a smooth, swirl-free surface matters
• Metal fabrication prep and deburring with controlled dust management
• DIY projects involving painting, staining, or refinishing where consistent prep is key

Pro tips for maximizing performance

• Begin with a coarser stage if needed, then progress to finer grits for a refined finish
• Between sessions, shake out dust, vacuum, or rinse to extend disc life
• Use the discs wet to reduce dust and improve edge retention on delicate surfaces
• Store in a clean, dry environment to preserve open-net structure and abrasive integrity
