3M 7100170823 Scotch-brite Durable Flex Belt 18 Inch Ao

Product Description

The 3M 7100170823 is a non-woven abrasive belt in the Scotch-Brite Durable Flex DF-BL series, designed for deburring, blending, and surface finishing on a wide range of metal workpieces. The belt combines a reinforced, low-stretch backing with conformable non-woven construction, allowing it to follow contours while delivering an aggressive yet controlled cut. The aluminum oxide abrasive mineral removes burrs and refines surfaces without significantly altering the base metal beneath. Metal fabricators, maintenance technicians, and tool-and-die professionals typically use this belt for detail work where surface quality and edge definition matter.

This belt is suited for use on ferrous and non-ferrous metals in both job-shop and production environments. Its flexible backing makes it particularly well-suited for belt sanders equipped with small-diameter contact wheels, where a stiffer belt would chatter or chunk. It handles blending weld seams, prepping surfaces for coating, and cleaning scale or oxidation from metal parts. The controlled cut rate reduces the risk of gouging, leaving a consistent, burr-free finish across the work surface.

Key Features

• Non-woven construction conforms to irregular and contoured metal surfaces
• Reinforced low-stretch backing supports aggressive conditioning with controlled cut
• Aluminum oxide mineral provides durable, consistent abrasive action on metal
• Resists chunking on belt sanders with small contact wheels
• Burr-free finish reduces secondary hand-finishing steps
• Effective for deburring, blending, weld seam finishing, and surface cleaning

Compatibility

Designed for use on ferrous and non-ferrous metals; compatible with belt sanders and finishing machines that accept non-woven abrasive belts, particularly those with small contact wheels where belt flexibility is required.

Installation Notes

Install on a compatible belt sander or abrasive finishing machine following the equipment manufacturer's belt-change procedure. Ensure the machine is fully de-energized and the drive wheel has come to a complete stop before changing belts. Confirm belt tracking and tension per the machine's specifications before resuming operation. Wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding or finishing equipment.
