3M PN-DH Aluminium Oxide, 115 mm, Extra Coarse Grade, P150 Grit 25 Per Pack

This grinding disc is designed for surface conditioning and finishing of metal substrates in industrial environments. It pairs a shaped abrasive grain with a non-woven web to remove material efficiently while preserving base geometry. The product is supplied in bulk for workshop and production use and is intended for low-pressure polishing and cleaning operations on a range of metals.

• Precision-shaped grain increases cut rate and abrasive life
• Non-woven construction reduces risk of gouging and undercutting
• Bright colour coding enables quick identification at Pace
• Suitable for stainless and soft metals under low pressure
• 22.23mm centre bore fits common angle grinder attachments

• Suitable for stainless steel surface finishing prior to assembly
• Ideal for removing oxidation from aluminium components
• used with Roloc-style attachments for handheld operations
• Can be used for deburring and blending on carbon steel parts
• Suitable for batch processing in automation cell pre-clean steps

It is designed for hook-and-loop and Roloc-type mounting systems used on angle grinders and rotary tools.

The precision-shaped abrasive grain reduces wear rate versus conventional non-woven discs, extending useful life under comparable operating conditions.

The maximum safe rotational speed for the disc is 13,300 r/min

Units are packaged in sets of 25 to support bulk usage and reduce changeover frequency.

The centre bore measures 22.23mm so adaptors or mandrels should match this dimension for secure mounting.
