3M 7100305426 | Hookit 5" Diameter 375L P80 Grit Aluminum Oxide Film Disc

Description

The 3M 7100305426 3M Hookit Film Disc 375L is a precision-engineered abrasive disc designed for controlled material removal and consistent surface preparation in demanding industrial and automotive environments. Constructed with aluminum oxide mineral bonded to a strong film backing, this abrasive disc delivers reliable cutting performance while maintaining a uniform scratch pattern throughout extended sanding operations, even under sustained pressure. The durable film-backed design improves dimensional stability and helps reduce edge wear, disc curling, and tearing commonly associated with paper-backed abrasives. Its 5-inch diameter format ensures compatibility with standard random orbital sanders and finishing tools used for metal finishing, panel preparation, and general surface conditioning. Formulated for durability, 3M 375L abrasive technology offers enhanced edge retention and longer disc life, supporting consistent results across multiple workpieces. The P80 grit grade provides an effective balance between material removal and surface refinement, making it suitable for intermediate sanding stages where surface leveling and preparation for subsequent finishing steps are required. As a film-backed sanding disc for metal finishing, this Hookit disc is commonly used in fabrication, automotive body repair, and industrial surface leveling applications where precision, repeatability, and abrasive longevity are critical.

Product Features and Benefits

Consistent P80 Grit Cutting Action

The aluminum oxide abrasive delivers steady material removal without excessive gouging. This makes p80 grit sandpaper suitable for controlled surface preparation before finer finishing steps.

Durable Film Backing Construction

The strong film backing resists tearing and edge wear during aggressive sanding. This durable film backing abrasive disc maintains shape and contact under sustained pressure.

Hookit Attachment System for Fast Changes

The Hookit backing allows quick disc changes while ensuring secure attachment during use. This improves efficiency in high-volume industrial sanding supplies applications.

Optimized for Metal Surface Preparation

Designed as a sanding disc for metal finishing, the disc performs consistently on steel, aluminum, and coated substrates. It supports smooth transitions and surface leveling.

Suitable for Automotive Refinishing Workflows

The controlled cut and stable backing make it effective among abrasive discs for auto body repair. It supports panel blending, filler shaping, and paint prep operations.
