Introducing Serious Grit 14-Hole Sanding Sheets

Meet the Serious Grit 14-Hole Sanding Sheet Assortment, a 50-sheet box designed for serious projects. Each sheet measures 3 x 5 in (80 mm x 133 mm) and features a precise 14-hole pattern that pairs well with compatible dust-control systems. Included are 10 sheets of grit 80, 120, 150, 180, and 220, giving you a ready-to-sand progression from rough shaping to fine finishing.

Key design and construction

  • FITS FESTOOL RTS 400 & MIRKA DEOS 353; ideal for detail work and tight corners.
  • HOOK & LOOP-BACKED FILM sheets with a heavy-duty polyester backing for strength and heat dissipation.
  • POLYESTER FILM backing adds tear resistance, helping edges stay intact during complex profiles.
  • ANTI-CL0G coating sheds dust before it clogs the surface, supporting consistent cutting power with a vacuum system.
  • FLATTER DISC design delivers a smoother finish than paper or mesh discs thanks to the film construction.

Performance and versatility

Designed for wet or dry use, these sheets are suitable for woodworking, auto body prep, metal finishing, drywall, epoxy, and painted surfaces. The coating and film help manage heat, supporting a steady removal rate and a swirl-free result when used with a proper dust extractor.

  • Wet/dry capability enables versatile finishing and paint removal tasks with compatible dust collection.
  • Dust-reducing design helps maintain cut power and minimizes downtime for cleanup.

Workflow and value

With 10 sheets per grit across a 50-sheet box, you have a complete progression from coarse shaping to fine finishing in one purchase. The durable film backing resists tearing around corners, while the anti-clog coating helps maintain effective surface area across grit ranges.
