3M 7100263903 Surface Conditioning Disc 4.5in Coarse Pn-dh

Product Description

The 3M 7100263903 is a 4.5-inch diameter Scotch-Brite Precision Surface Conditioning Disc designed for demanding surface work on metal substrates. It uses precision-shaped ceramic grain embedded in a nonwoven backing, delivering aggressive material removal while maintaining consistent surface finish. Rated to 13,300 RPM and graded Coarse, this disc is built for right angle grinder use in shop and field environments. HVAC fabricators, welders, pipefitters, and metal finishing tradespeople rely on this disc type for fast, controlled results across grinding, blending, deburring, and cleaning operations.

This disc is suited for use on stainless steel, carbon steel, aluminum, and soft metals. The PN-DH product configuration attaches via hook and loop, making wheel changes fast without additional hardware. The nonwoven construction conforms to contoured surfaces and workpiece edges, making it effective for deburring, radiusing, and blending weld seams or machined surfaces. Its brown color coding aids quick grade identification in multi-disc environments where coarse and fine grades are used side by side.

Key Features

• Precision-shaped ceramic abrasive grain for consistent cut rate and extended disc life
• Coarse grade for aggressive grinding, blending, deburring, and cleaning tasks
• Hook and loop attachment for fast, tool-free disc changes on compatible right angle grinders

Compatibility

Designed for use with right angle grinders equipped with a hook and loop backing pad. Suitable for work on stainless steel, carbon steel, aluminum, and soft metal substrates.

Installation Notes

Install and remove this disc only with the grinder powered off and disconnected from its power source. Confirm the grinder's no-load RPM rating meets or does not exceed the 13,300 RPM disc rating before mounting. Seat the hook and loop backing fully before operation to prevent disc separation during use. Wear appropriate eye protection and gloves; nonwoven discs on high-speed grinders can shed fibers if damaged or improperly seated.
