3M 7000121142 Scotch-brite Durable Flex Belt 18 Inch

Product Description

The 3M 7000121142 is a nonwoven abrasive belt in the Scotch-Brite Durable Flex DF-BL family, designed for detail work on metal surfaces. It handles deburring, blending, and surface finishing while leaving a burr-free result without significantly altering the base metal. The reinforced, low-stretch backing delivers aggressive cutting action and consistent material removal. Aluminum oxide (AO) mineral construction provides durable abrasion across a range of metal types. This belt is used by metalworkers, fabricators, and finishing technicians who need controlled cut without gouging.

This belt is suited for use on belt sanders equipped with small contact wheels, where flexibility and edge durability are critical. The conformable nonwoven construction allows it to follow contours and reach tight detail areas. It performs well in both light production and maintenance environments where consistent surface prep and blending are required on ferrous and non-ferrous metals.

Key Features

• Nonwoven construction conforms to surface contours for detail deburring and blending
• Reinforced low-stretch backing supports aggressive conditioning without loss of flexibility
• Superior edge durability extends belt life during sustained use
• Controlled cut eliminates gouging and leaves a burr-free finish
