3M 7100192038 Hookit Film Disc 375L 5 Inch P500 Grit

Product Description

The 3M 7100192038 is a Hookit film disc in the 375L series, designed for sanding and finishing work across a range of substrates. It uses a premium aluminum oxide abrasive grain that delivers a fast cut rate and extended service life, reducing how often discs need to be replaced. The film backing is tear-resistant and flexible, making it well-suited for contoured and curved surfaces. At 5 inches in diameter with a P500 grit rating, this disc is aimed at finish sanding applications where surface consistency matters. It is installed and serviced by body technicians, painters, and trade professionals working in metal fabrication, auto body, and surface preparation.

The 375L disc is built for finish sanding on contoured surfaces where flexibility and tear resistance are critical. The open-coat construction paired with a load-resistant coating helps the disc shed dust and debris, keeping the abrasive cutting freely across both flat and irregular surface profiles. It is appropriate for use on metal, painted surfaces, and composite substrates in both production and repair environments where a uniform finish is the target before coating or painting.

Key Features

• Premium aluminum oxide grain provides a fast cut rate and extended disc life
• Tear-resistant film backing holds up on contoured and irregular surfaces
• Open-coat construction delivers an aggressive, consistent cut
• Load-resistant coating resists clogging from dust and debris
• Hookit attachment system allows quick disc changes and reuse during the disc lifespan
• Flexible backing conforms well to curved and contoured workpieces

Compatibility

Designed for use with 3M Hookit backup pads and random orbital sanders that accept 5-inch hook-and-loop discs.

Installation Notes

Disc attachment and removal requires a compatible Hookit hook-and-loop backup pad. Ensure the backup pad surface is clean and free of debris before attaching the disc to maintain secure contact. Inspect the disc before each use and replace if the abrasive is loaded, the film backing shows damage, or adhesion to the pad is compromised. Follow all applicable workshop safety guidelines, including respiratory protection when sanding materials that generate fine particulate.
