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.

Features & Benefits

• 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

Applications

• 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

What bore size is needed for correct mounting?

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

Which substrates are compatible with this abrasive grain?

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

How does the backing material affect finish control?

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

What pack quantities are available for production environments?

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

Which tool attachments are commonly used with these discs?

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