3M Black & Purple Diamond Abrasive Disc for Metal Rust Paint Oxide Removal

01｜Product Overview

This series includes two types of cup abrasive discs: 3M Black Diamond and XT Pro Purple Diamond. They are made of premium silicon carbide abrasive, 3M base material and plastic cup backing, serving as heavy-duty surface conditioning abrasives. Featuring open mesh fiber structure and strong cutting power, they produce low sparks during grinding. The discs can rapidly remove heavy rust, old paint, coating and weld marks without creating pits on workpieces and keep base material intact. They are widely used for surface pre-treatment of metal sheets and hardware parts, balancing grinding efficiency and processing yield.

02｜Product Feature

*Constructed with silicon carbide abrasive for powerful cutting and excellent rust & paint stripping performance

*Open mesh fiber structure allows debris to pass through freely and prevents clogging

*Plastic cup backing with center mounting hole, stable installation for angle grinders

*Black abrasive layer and high-strength fiber base, wear-resistant and anti-breakage for edge grinding

*Low spark generation during grinding, less likely to burn workpiece surface and reduce rejection rate

*Uniform finished surface without pits, keeps workpiece substrate intact

04｜Product Advantages

*High cleaning efficiency: Quickly strip heavy rust, aged paint, oxide coating and level discolored weld spots

*Anti-clogging: Open chip removal structure maintains stable cutting force during long continuous grinding without frequent cleaning

*Low spark for safer operation: Less sparks than conventional grinding discs, suitable for heat-sensitive workpieces

*Substrate-friendly: Aggressive yet controllable cutting, only removes surface defects without gouging or pitting workpieces

*Long service life: High-strength fiber base resists cracking on edges for extended service

*Consistent finishing: Uniform grinding texture provides qualified base surface for subsequent spraying, welding and other processes

05｜Wide Range of Applications

These abrasive discs are mainly used for surface pre-treatment of various metal workpieces. They clean rust, old paint and coatings on metal tubes, sheets and hardware components, and level weld seams & discolored weld areas. They are suitable for stainless steel kitchenware, metal doors, pressure vessels, sheet metal parts and general hardware, ideal surface conditioning tools before coating and after welding.
