Compare 5" 5 hole PSA Supergrit discs with standard sanding discs. See the trade-offs in dust extraction, adhesive backing, and grit range to choose the right disc for your project.
Quick answer
If you need efficient dust extraction and a secure adhesive backing for detailed sanding, 5" 5 hole PSA Supergrit discs are the better choice over standard discs without holes or with hook-and-loop backing.
Dust extraction makes a real difference
The five-hole pattern on Supergrit discs allows sanding dust to be pulled through the disc into a vacuum system. This keeps the abrasive surface cleaner and reduces the amount of airborne dust. Standard discs without holes or with a different hole pattern may clog faster and leave more dust on the workpiece.
PSA vs hook-and-loop backing
PSA (pressure-sensitive adhesive) backing provides a firm, non-slip hold on the sander pad. It is ideal for heavy sanding or when you need consistent pressure without the disc shifting. Hook-and-loop discs are easier to swap but can wear out or lose grip over time. PSA discs are single-use but offer a more secure bond for the entire sanding session.
Trade-offs at a glance
- Dust extraction: 5-hole discs allow vacuum extraction, keeping the surface cleaner and extending disc life. Standard discs without holes may clog faster.
- Adhesive backing: PSA backing holds firmly without slipping, ideal for consistent pressure. Hook-and-loop is easier to change but can lose grip over time.
- Grit range: Supergrit discs offer a wide grit range (40 to 280) for coarse to fine sanding. Standard discs may have a narrower selection.
