Overview

Serious Grit delivers a versatile sanding sheet set designed for a wide range of projects. The 3 x 5 inch rectangles feature a 14-hole pattern that helps heat dissipation and maintains a flat, consistent surface. The aluminum oxide abrasive is paired with a robust polyester film backing to provide durability and a smooth finish. This assortment is compatible with popular electric detail sanders such as the Festool RTS 400 and Mirka Deos 353, making it a flexible choice for workshops, hobby spaces, and DIY tasks.

What’s inside

  • Grits: 80, 120, 150, 180, 220; 10 sheets of each grit; total 50 sheets
  • Size: 3 x 5 inches (80 mm x 133 mm) with a 14-hole pattern per sheet

Durability and performance

  • Heavy-duty polyester film backing between the abrasive grain and hook-and-loop backing for strong discs and reliable heat dissipation
  • Anti-clog coating helps shed dust before it clogs the surface, especially when used with a dust extractor
  • Film-based construction promotes a flatter, stronger disc and a smoother finish compared with paper or mesh discs

Real-world use and tips

Ideal for wood, metal, drywall, epoxy, and painted surfaces. Wet or dry sanding expands its applications, including paint removal and smoothing filler. For best results, pair with an efficient dust extractor and progress from coarser to finer grits for a clean, swirl-free finish.
