3M PN-DH Aluminium Oxide, 125 mm Resin, Coarse Grade, 8 Grit 25

This abrasive disc is designed for surface conditioning and metal removal tasks in industrial settings. It combines a ceramic abrasive material with a non‑woven backing to provide aggressive cutting while preserving base material geometry. Supplied in a pack of 25, the product is intended for low‑pressure applications across various ferrous and non‑ferrous substrates used in automation, electronics and mechanical workshops.

• Ceramic abrasive grain delivers fast material removal and longer life
• Resin bond ensures consistent abrasive performance under load
• Coarse grit 8 provides aggressive stock removal without gouging
• 22.23mm bore permits secure centring on compatible tool spindles
• Non‑woven construction maintains surface profile while conditioning

• Suitable for stainless steel deburring and edge blending in fabrication
• Ideal for removing weld scale and surface oxidation on carbon steel
• Used for finishing aluminium components without altering dimensions
• Can be used for preparatory surface cleaning prior to assembly

The disc requires a 22.23mm centre bore to fit standard mandrels and hook‑and‑loop adaptors used in bench and portable grinders.

The ceramic material is formulated for stainless steel, carbon steel, aluminium and other soft metals under low‑pressure conditioning.

The non‑woven web balances conformability and durability so it conditions surfaces without removing profile or causing undercutting.

This product is supplied as a 25 pack to support repeatable runs and minimise changeovers.

They are typically employed with hook‑and‑loop or Roloc™ style attachments for Rapid exchange and positional stability.
