3M HD-DH

This hook & loop sanding disc is a medium-grade, heavy-duty surface conditioning disc designed for industrial finishing and light grinding tasks. It combines an aluminium oxide abrasive with a conformable non-woven backing to process, refine and blend metallic and non-metallic surfaces in automated and manual workflows. The product is supplied in bulk for workshop and production environments where consistent abrasive behaviour and repeatable surface results are required.

• Aluminium oxide abrasive delivers sustained material removal and cut rate
• Non-woven web backing reduces risk of gouging while conforming to contours
• Black backing with white font identifies heavy-duty, load-resistant discs
• Rated for maximum safe speed up to 12,000 r/min for high-speed tools
• Hook and loop attachment enables Rapid disc changes on pad systems

• Suitable for deburring machined steel components in automation cells
• Ideal for edge breaking on electrical enclosures and panels
• Used for blending weld seams on mechanical assemblies
• Can be used for light grinding and finishing of aluminium parts
• Suitable for integration into robotic sanding stations for volume processing

It uses a hook and loop Interface compatible with hook-and-loop back-up pads and quick-change pad systems.

The heavy-duty construction preserves edge shape and helps retain abrasive life during edge wear under high contact pressure.

The discs are supplied in packs of 50 to reduce changeover frequency in continuous operations.

The product is a medium-grade disc with a nominal 150 grit mineral suited to general finishing and refining.
