3M HD-DH

This hook & loop sanding disc is a non-woven surface conditioning pad designed to prepare metal and other substrates for finishing and blending in industrial settings. It combines aluminium oxide abrasive with a conformable non-woven backing to perform light grinding, deburring, edge breaking and surface refinement on production lines and robotic systems. The product is supplied in packs suitable for workshop use and fits hook-and-loop backup pads for efficient attachment.

• Extra coarse 60 grit PSG aluminium oxide delivers aggressive material removal
• Black non-woven web backing resists gouging while conforming to contours
• Rated maximum safe speed 8,600 r/min for high-speed rotary tools
• Hook and loop attachment enables Rapid disc changes during production

• Suitable for metal prep and surface conditioning prior to coating
• Ideal for deburring machined edges on mechanical components
• Used for blending weld seams in automated fabrication cells
• Can be used for cleaning and radiusing in electrical enclosure work
• Suitable for finishing tasks in electronics assembly jigs

The disc uses aluminium oxide with precision-shaped grain to provide consistent cutting and extended life on ferrous materials.

It is designed for hook-and-loop backed pads and pairs with low-profile backup pads for secure mounting.

The conformable web reduces the risk of gouging and helps produce a blended surface while maintaining aggressive cut.

It is intended for industrial use in automation, mechanical and metal-preparation workflows where repeatable surface conditioning is required.
