Norton 66261131545 Hook Loop Disc 5 in 180 Grit

Product Description

The NORTON 66261131545 is a 5-inch hook-and-loop abrasive disc designed for random orbital and disc sanders used in surface preparation, finishing, and blending applications. Built on a B-weight paper backing, this coated disc uses aluminum oxide abrasive grain bonded to a flexible substrate. At 180 grit, it falls in the very fine grade range, making it well suited for final sanding passes before finishing, light stock removal, and surface smoothing on wood, composite, and similar materials. The disc weighs approximately 0.009 pounds and attaches via hook-and-loop fastening for fast pad changes without tools.

This disc is used in woodworking shops, cabinet shops, and light fabrication environments where consistent scratch patterns and controlled material removal are required. The A275 series designation indicates a general-purpose finishing disc. It is appropriate for use on bare wood, previously finished surfaces, and composite panels. The flexible paper backing conforms to slightly contoured surfaces, allowing more even abrasive contact. No vacuum holes are present on this disc, so it is intended for use on sanders without dust extraction through the pad.

Key Features

• 5-inch diameter with hook-and-loop attachment for tool-free disc changes
• 180 grit aluminum oxide abrasive for very fine finishing and surface prep
• B-weight paper backing provides flexibility for contoured surface contact
• Coated abrasive construction for consistent grain distribution and cut rate
• No vacuum holes — compatible with solid-face hook-and-loop sanding pads
• Part of the A275 general-purpose finishing series

Compatibility

Designed for use with 5-inch hook-and-loop random orbital sanders and disc sanders equipped with solid-face sanding pads that do not require vacuum-hole alignment.

Installation Notes

Press the disc firmly onto a clean, dry hook-and-loop sanding pad before powering the tool. Inspect the pad surface for worn hooks before attaching, as a degraded pad will reduce disc retention and tracking. Allow the sander to reach full speed before contacting the work surface. Replace the disc when abrasive grain becomes glazed or loaded, as a spent disc generates heat without effective material removal.
