3M 7000120700 Abrasive Belt 3/4x18 in Aluminum Oxide Very Fine

Product Description

The 3M 7000120700 is a non-woven abrasive belt designed for fine surface finishing, deburring, and blending on metal, wood, and composite materials. Measuring 3/4 inches wide by 18 inches long, it fits compact belt finishing tools and file belt sanders commonly used in fabrication, maintenance, and toolroom applications. The belt uses aluminum oxide abrasive in a very fine grade, bonded to a flexible scrim backing that conforms to contoured and flat surfaces alike. It supports both wet and dry operation, giving technicians flexibility in their finishing process. Licensed tradespeople and skilled fabricators in metalworking and industrial maintenance are the primary installers.

This belt is suited for light material removal, surface conditioning, and pre-polish blending on narrow workpieces or in tight geometries where wider belts cannot reach. The SC-BS series non-woven construction cushions the abrasive against the workpiece, reducing the risk of gouging or over-cutting on finished surfaces. Wet operation is supported, making it appropriate for applications where coolant or water is used to control heat or improve surface finish quality. It is commonly used in maintenance shops, pipe fitting environments, and precision metal fabrication settings.

Key Features

• Aluminum oxide abrasive delivers consistent cut on ferrous and non-ferrous metals as well as wood composites
• Very fine grade suited for finish blending, light deburring, and surface conditioning
• Non-woven construction with scrim backing conforms to irregular and contoured surfaces
• Supports both wet and dry operation for flexible use across finishing environments
• Compact 3/4 inches x 18 inches size fits narrow belt sanders and file belt tools

Compatibility

Designed as a replacement or consumable abrasive belt for 3/4 inch by 18 inch belt sanders and narrow file belt finishing tools. Confirm tool belt size specifications before installation.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using belt sanders or portable file belt tools. Power down and unplug the tool before changing the belt. Ensure the belt tracking is adjusted properly after installation to prevent edge wear or belt slippage during operation. When using in wet mode, verify the tool is rated for wet operation before applying coolant or water.
