Norton 66261139366 Sanding Sheet 240 Grit Silicon Carbide

Product Description

The NORTON 66261139366 is a 240-grit silicon carbide sanding sheet rated Very Fine grade, designed for dry and wet sanding applications across a range of trade and industrial finishing tasks. Built on a B-weight paper backing with an open coat density, this sheet delivers consistent abrasion with reduced loading on the workpiece surface. The silicon carbide abrasive cuts hard, smooth surfaces efficiently, making it well-suited for finishing metal, fiberglass, plastics, and painted surfaces. Licensed trades and skilled finishers who require controlled material removal at finer grits will find this sheet performs reliably in both hand-sanding and block-sanding setups.

This sanding sheet is appropriate for surface prep work in metal fabrication, body shop finishing, composite work, and general industrial applications where a Very Fine 240-grit cut is needed. Its wet-or-dry capability makes it useful in stages where water or solvent lubrication is used to minimize heat and swarf buildup. The open coat construction helps the sheet resist clogging during extended use on softer or resinous materials. It is part of the NORTON T414 series, a standard sheet format used across hand-sanding and flat-pad power tool applications.

Key Features

• 240-grit silicon carbide abrasive for Very Fine material removal
• B-weight paper backing balances flexibility and support for flat surface work
• Open coat density reduces loading and extends usable sheet life
• Wet-or-dry rated for use with water or solvent lubrication
• Part of the T414 series for consistent sizing and fit compatibility

Compatibility

Designed as a standard sanding sheet for hand blocks, flat-pad sanders, and manual finishing applications that accept sheet-format abrasives in the T414 series dimensions.

Installation Notes

Sanding sheets of this type are installed by finishing tradespeople, fabricators, and surface prep technicians. Secure the sheet firmly to a sanding block or pad before use to prevent slipping. When using wet, ensure the workpiece material and any coatings are compatible with moisture exposure. Dispose of worn sheets promptly, as a loaded or glazed abrasive generates heat and reduces cut quality.
