Serious Grit 3" x 5" 1/2 Inch 14-hole foam sanding pads are designed for ultra-flexible sanding with Festool RTS 400, Mirka DEOS 353, and other 80x133mm sanders with 14-hole hook & loop interfaces.

These pads use a 1/2" low-density open-cell foam that conforms easily to curves, profiles, and moldings without cutting through edges or high spots.

Ideal for removing light surface imperfections and prepping curved trim or detailed profiles, the premium silicon carbide abrasive cuts cleanly and evenly across a variety of surfaces.

Hook & loop backing allows quick pad changes, and the foam construction supports both wet and dry use for versatile performance.

Each box contains 10 foam sanding pads.

Mixed grit box includes 2 sheets of each - P120-150, P150-180, P220-240, P280-380, and P450-600 grit finish.

  • FITS FESTOOL & MIRKA SANDERS - Serious Grit 3" x 5" (80x133mm) 14-Hole 1/2" foam hook & loop sanding pads are compatible with the Festool RTS 400, Mirka DEOS 353, and any other 3x5 hook & loop detail sanders.
  • MADE IN USA - we're proud to manufacture our 3x4 foam sanding pads in the USA, supporting American jobs and small businesses.
  • FAST-CUTTING SILICON CARBIDE GRAIN - compared with aluminum oxide, silicon carbide grain is sharper and harder, producing faster cut rates, less sanding time, and better finish quality.
  • 1/2" THICK FLEXIBLE FOAM - the ultra low-density 1/2" thick open cell polyurethane foam maximizes flexibility and allows sanding of detailed contours and complex shapes without burning through. Ideal for cabinetry, furniture refinishing, paint work, and fine finish work.
  • WET/DRY COMPATIBLE - These sanding sponges are wet/dry compatible and ideal for sanding all surfaces, including bare wood, latex or oil paint, stained wood, autobody, metal, epoxy, gelcoat, plaster, etc.

Note that because the foam conforms to contours, we catalog these by their finish quality or scratch pattern rather than the grit. Here's a handy foam grit conversion chart you can use to help select which to choose:

Our Secret Formula

We'll let you in on some secrets - here are 3 of the ingredients that make our foam worthy of the Serious Grit brand.

Silicon Carbide Grain

Silicon carbide is sharper and harder than aluminum oxide, making it ideal for fine finishing on paint, primer, and contours. It cuts fast, leaves a smoother surface, and won’t leave behind deep scratches, especially in higher grits.

Polyurethane Foam

Our flexible polyurethane foam backing conforms to curves, edges, and complex profiles without folding, bunching, or burning through. It distributes pressure evenly, so you get a consistent finish without compromising the surface.

Made in USA

That's right, our green foam sanding pads are 100% made from scratch in the United States. From the polyurethane foam to the thermoplastic resin and silicon carbide grain, these are some true homegrown sanding pads.
