3M 7000045654 Microfinishing Film Disc 4.328 in Ao Hook Loop

Product Description

The 3M 7000045654 is a Hookita Microfinishing Film Disc in the 3M 366L series, designed for precision surface finishing across a wide range of materials. It uses micron-graded aluminum oxide abrasive bonded to a durable polyester film backing. This combination delivers a fast cut rate and a consistent, uniform finish. The disc measures 4.328 inches in diameter and is rated for up to 12000 RPM. It is suited for professional finishing work on wood, solid surface composites, plastic, fiberglass, paint prep, primers, e-coat, coatings, corrosion removal, and bare metal. Tradespeople and finishing technicians handling multi-step surface preparation rely on this disc for repeatable results.

This disc fits into multi-step finishing and surface prep workflows where close tolerances and a uniform scratch pattern are required. Common applications include paint preparation, e-coat removal, primer leveling, corrosion removal, and final finishing on metal, plastic, and composite surfaces. The load-resistant coating helps maintain cut performance in dusty or debris-heavy environments. The Hookita hook and loop attachment system makes it practical for rapid disc changes during sequential grit progressions.

Installation Notes

Installation is performed by finishing technicians and surface prep professionals using compatible random orbital or right-angle tools with a hook and loop backing pad. Verify that the tool RPM rating does not exceed 12000 RPM before mounting the disc. Inspect the backing pad for wear or contamination before attachment, as a damaged pad can cause uneven disc contact and inconsistent finish results. Always follow applicable personal protective equipment requirements when operating abrasive finishing tools.
