3M Scotch-Brite Durable Flex Belt DF-BL, 457 mm 13mm, Medium Grade

This sanding belt is a non-woven surface conditioning product designed for cleaning, blending, deburring and finishing operations on metal components in industrial settings. It is intended for use on belt sanders with small contact wheels and other machines where flexibility and reduced loading are required, offering a cooler running abrasive action suitable for automation, electrical, electronics and mechanical workshops.

• Aluminium oxide mineral delivers sustained cutting performance
• Non-woven nylon web resists loading and reduces heat build-up
• Medium grade provides balanced cut rate and surface refinement
• Reinforced low-stretch backing improves edge durability
• Brown colour aids Visual identification in stores and production
• Flexible construction reduces risk of chunking on small wheels

• Suitable for deburring welded seams on steel assemblies
• Ideal for satin finishing and blending of panel surfaces
• Used for weld cleaning during robotic or manual operations
• Suitable for detail finishing on fabricated components
• Can be used with portable file belt sanders for on-site work

It is formulated for a variety of metals including stainless and carbon steels, offering surface modification without significant dimensional change.

The open non-woven structure reduces loading and promotes cooler operation, minimising discolouration and part distortion.

It performs well on belt sanders with small contact wheels, backstands, stroke sanders and portable belt machines where flexibility is needed.

The low-stretch reinforcement maintains belt stability under load, supporting consistent abrasive contact and improved edge life.
