Pro-source 5590012515PRO 320 Grit Hook Loop Disc 3 Inch 10 Pack

Product Description

The PRO-SOURCE 5590012515PRO is a 3-inch hook-and-loop abrasive disc designed for fine surface preparation and finishing work. This coated disc uses aluminum oxide abrasive at 320 grit, which falls in the extra fine grade range. That makes it well-suited for light material removal, final sanding passes, and surface smoothing before finishing or coating application. The flexible backing allows the disc to conform to slightly contoured surfaces. Sold in a 10-pack, these discs are a practical stock item for shops and service vans that run consistent finishing operations.

This disc fits into workflows where controlled, fine abrasion is required. Typical applications include wood finishing, painted surface prep, metal deburring, and composite surface work in light manufacturing, cabinet shops, auto body, and general maintenance environments. The hook-and-loop attachment system allows fast disc changes on compatible random orbital and disc sanders, reducing downtime during multi-stage sanding sequences. The 320 grit rating makes this disc appropriate for penultimate or final sanding stages rather than aggressive stock removal.

Key Features

• 320 grit extra fine aluminum oxide abrasive for controlled, smooth material removal
• Coated abrasive construction provides consistent cut across the disc surface
• Flexible backing allows conforming contact on slightly curved or irregular surfaces
• Hook-and-loop attachment for tool-free disc changes on compatible sanders
• 3-inch diameter fits standard small random orbital and detail sanders
• Sold in a 10-pack for convenient shop stocking and van inventory

Compatibility

Designed as a replacement or consumable-stock disc for 3-inch hook-and-loop random orbital sanders and disc sanders that accept coated abrasive discs in this diameter.

Installation Notes

Align the disc squarely with the sander pad before pressing the hook-and-loop surfaces together to ensure full contact and even wear. Inspect the sander backing pad for worn or missing hook material before installing a new disc, as a degraded pad will cause uneven abrasion and premature disc failure. Do not exceed the maximum RPM rating of the sander being used. Discard discs that show loading, glazing, or visible abrasive breakdown to maintain consistent finish quality.
