Norton 66261140520 5 Inch 120 Grit Ceramic Sanding Disc

Product Description

The NORTON 66261140520 is a 5-inch hook and loop sanding disc engineered for aggressive material removal with a fine finish. It features a ceramic abrasive grain bonded to a B-weight paper backing, giving it the rigidity needed for flat surface work while maintaining enough flex for contour sanding. At 120 grit, this disc sits in the fine grade range, making it well-suited for final stock removal passes and surface prep before finishing. The hook and loop attachment system allows fast disc swaps without tools. Installers, finish carpenters, and surface prep technicians are the primary users of this consumable abrasive.

This disc is used in residential and light commercial surface preparation applications. Typical uses include wood sanding, paint and primer scuffing, light metal deburring, and drywall feathering. The 5-inch diameter fits standard random orbital and disc sanders equipped with hook and loop backing pads. The ceramic grain cuts faster and lasts longer than aluminum oxide under moderate to heavy pressure, making it a reliable choice for repetitive production work. No vacuum holes are included, so it is intended for sanders without dust-extraction port patterns.

Key Features

• 120 grit ceramic abrasive for fast cutting with fine surface results
• B-weight paper backing provides a balance of stiffness and flexibility
• Hook and loop attachment for tool-free disc changes on compatible sanders
• Coated abrasive construction for consistent grain distribution across the disc surface
• No vacuum holes — suitable for solid-pad random orbital sanders
• Part of the NORTON A975 series

Compatibility

Designed for use with 5-inch hook and loop random orbital and disc sanders that accept solid-face backing pads without dust-extraction holes.

Installation Notes

Press the disc firmly onto the hook and loop backing pad to ensure full surface contact before starting the sander. Inspect the backing pad regularly for worn hooks, as a degraded pad will cause the disc to slip or detach during use. Do not apply excessive downward pressure — let the abrasive do the work to extend disc life and avoid loading the grain. Discard discs when grain loading, glazing, or tearing is visible.
