3M 7010309449 Abrasive Disc 8 Inch 80 Grit Ceramic Ao

Product Description

The 3M 7010309449 is an 8-inch diameter coarse-grit abrasive disc from the Green Corps 246U line, designed for demanding surface preparation work in automotive and metal finishing applications. Built on a D-weight backing for exceptional durability, this disc uses a ceramic aluminum oxide mineral blend that delivers a fast cut rate and extended service life. The pressure-sensitive adhesive (PSA) attachment system allows quick disc changes on compatible random orbital and disc sanders. At 80 grit, it removes material aggressively without excessive loading on the abrasive surface.

This disc is well suited for shaping plastic body filler, stripping paint from damaged panels, and refining scratches on bare metal or fiberglass surfaces. Body shop technicians and auto refinishing professionals rely on this type of abrasive for pre-paint surface prep on both collision repair and custom fabrication work. The 8-inch diameter fits standard PSA backing pads common in professional automotive bodywork setups.

Key Features

• Ceramic aluminum oxide mineral blend for fast cut rate and long abrasive life
• D-weight backing provides heavy-duty durability on paint, metal, and fiberglass
• Pressure-sensitive adhesive attachment for fast, tool-free disc changes
• 80 grit coarse cut suited for material removal and scratch refinement on bare metal
• Versatile for plastic filler shaping, paint stripping, and surface preparation

Compatibility

Designed for use with PSA-style backing pads that accept 8-inch diameter abrasive discs, as commonly found on random orbital and disc sanders used in automotive bodywork and surface preparation.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from the air supply or electrical source. Ensure the PSA backing pad surface is clean and free of debris before attaching the disc to achieve a secure bond. Automotive body technicians should follow applicable workplace safety guidelines for abrasive tool operation, including proper eye and respiratory protection when sanding metal, paint, or fiberglass.
