3M 7000119684 Hook and Loop Disc P320 3 Inch Ao

Product Description

The 3M 7000119684 is a coated abrasive hook-and-loop disc designed for fine power sanding and finishing work in auto body applications. Built on a lightweight A-weight paper backing, this 3-inch disc carries aluminum oxide abrasive in an open-coat construction that delivers a fast, aggressive cut while leaving a uniform surface finish. The load-resistant coating resists clogging, and the Hookita hook-and-loop attachment system allows quick disc changes and reuse throughout the disc's service life. Rated at 15,000 RPM, it is suited for orbital and random orbital sanders used in feather-edging and primer sanding operations.

This disc is primarily used in automotive refinishing and collision repair environments, covering tasks such as feather-edging body filler, scuffing primer, and preparing surfaces for topcoat. The P320 grit level targets fine surface preparation where scratch control and finish consistency are critical. Open-coat construction minimizes loading when working on soft materials like primer and body filler, making it a practical choice for body shop technicians and detail-focused trades professionals handling light sanding stages.

Installation Notes

This disc is installed and removed by hand using the hook-and-loop backing — no tools required for disc changes. Confirm the sander backing pad is clean and free of debris before attaching the disc to ensure full contact and secure hold. Do not exceed the 15,000 RPM maximum speed rating. Inspect the disc before each use and discard if the abrasive surface is loaded, torn, or the backing is damaged.
