3M PN-DH Aluminium Oxide, 178 mm, Fine Grade, P150 Grit 25 Per Pack

This grinding disc is designed for surface conditioning and finishing of metal substrates in industrial settings. It combines precision-shaped abrasive grain with a non-woven web to abrade and refine stainless steel and other metals while maintaining the base material’s geometry. Supplied in packs for workshop or production-line use, it is suitable for low-pressure operations across automation, electronics, electrical and mechanical environments.

• Precision-shaped grain increases cut rate and lifespan
• Non-woven construction reduces risk of gouging or undercutting
• Fine P150 grit yields consistent finishing results
• Bright colour coding aids Rapid identification in busy areas
• 22.23mm centre bore ensures secure attachment to tools
• Maximum safe speed 8,600 r/min supports high-speed applications

• Suitable for deburring stainless steel components prior to assembly
• Ideal for cosmetic finishing on aluminium panels in automated lines
• Used for surface preparation of carbon steel before bonding
• Can be used for cleaning weld seams in mechanical fabrication
• Suitable for maintenance grinding in electrical cabinet work

The discs are provided in packs of 25 to support continuous production or maintenance schedules.

Soft metals, aluminium, carbon steel and stainless steel can be cleaned and finished without changing part geometry.

It can replace Fibre and flap options at P150 and finer, reducing process steps while avoiding material damage.

The 22.23mm bore is intended for standard hook-and-loop or Roloc-style mounting systems that require a 7/8 in centre interface.
