3M HD-DH

This hook-and-loop sanding disc is a heavy-duty non-woven web surface conditioning disc intended for industrial finishing and material removal tasks. Designed for abrasive operations on metal and other substrates, it combines aluminium oxide mineral on a conformable web to provide aggressive cutting and extended service life at high spindle speeds, making it suitable for workshop and production environments in automation, electronics, electrical and mechanical sectors.

• Extra-coarse aluminium oxide for Rapid material removal
• Rated for high RPMs up to 12,000 r/min for fast throughput
• Non-woven web backing resists gouging while conforming
• Hook-and-loop attachment enables quick disc changes
• Black backing with white font simplifies grade identification

• Suitable for light grinding and deburring on mild steel components
• Ideal for edge breaking and radiusing in fabricated parts
• Used for surface blending and refining in electronic chassis work
• Can be used for finishing and cleaning electrical enclosures
• Suitable for robotic sanding cells processing repetitive parts

The disc uses aluminium oxide with precision-shaped grain to maintain cutting Ability on ferrous materials while offering consistent finish rates.

It uses a hook-and-loop fastening system allowing Rapid replacement and reduced downtime in repetitive production tasks.

The backing is black with contrasting white font which denotes the heavier-duty family and helps technicians select the correct grade quickly.

Packs contain 50 discs, appropriate for operations requiring frequent changes or high-volume processing.

The specification is 60 grit extra-coarse, intended for aggressive stock removal while still providing surface conditioning.
