Buying Guide

Choose the right backing style

Net-backed discs improve dust extraction on composite laminates compared with solid PSA or paper-backed discs, reducing clogging and heat buildup

Match disc diameter to your sander

Select 5-inch or 6-inch hook-and-loop discs to match your pad size so the grit covers the working area without overhang or missed spots

Pick appropriate grit progression

Start with coarser grits for shaping or removing resin and progressively move to finer grits (e.g., 320–600+) for finish sanding and feathering joints on composites

Prioritize dust extraction capability

Discs designed for dust collection (net-disc construction) help maintain abrasive life and visibility when working with composite dust, which can be fine and hazardous

Consider pack size and value

Buying larger multi-packs can lower per-disc cost for routine composite work; compare pack counts and grit mixes to your project usage
