3M PN-DH Aluminium Oxide, 150 mm, Medium Grade, P150 Grit 25 Per Pack

This grinding disc is a non‑woven surface conditioning product designed to prepare and finish metal substrates in industrial settings. It combines an engineered abrasive technology with a conformable web to remove contaminants and refine surfaces while preserving the parent geometry, making it suitable for workshop and production environments in automation, electronics, electrical and mechanical sectors.

• Precision-shaped grain provides Faster material removal and longer life
• Medium P150 grit delivers balanced cutting and surface finish
• 8mm bore enables compatibility with standard mandrels and attachments
• Bright colour coding aids quick identification on busy benches
• Rated to 10000 r/min for high-speed hand and power-tool use

• Suitable for de-burring stainless steel components prior to assembly
• Ideal for blending weld seams on mechanical assemblies
• Used for surface preparation of aluminium panels before coating
• Can be used for finishing forged or machined parts in automation lines
• Suitable for light cleaning of carbon steel in electrical enclosures

The abrasive uses shaped abrasive grains embedded in a non‑woven web that abrades without cutting deep into the substrate, reducing risk of undercutting or gouging.

The discs are supplied in packs of 25 to support repetitive production tasks and tool-change routines.

It is suitable for stainless steel, aluminium, carbon steel and other soft metals under low-pressure conditions.

Its balance of conformability and cut-rate enables replacement of multiple operations, such as swapping between Fibre and flap discs for certain P150 and finer tasks.
