3M 268L Hookit Hook & Loop Sanding Disc 5" 100 Micron Aluminum Oxide Microfinishing Film 5 Hole Bulk-50 51111545478

3M 268L Hookit 100 Micron Sanding Disc Use

3M 268L Hookit 100 micron sanding disc is a 5 inch, 5-hole abrasive disc designed for microfinishing tasks where a precise and consistent uniform finish is required. This disc uses a premium micron graded mineral on a high strength polyester film, so the abrasive cut stays controlled while the backing resists tearing during demanding shop work. The Hookit style makes disc attachment and removal quick on compatible hook and loop backup pads, supporting fast disc changes during staged finishing. The 100 micron grade targets intermediate microfinishing steps, refining surfaces between more aggressive sanding and final polishing. The disc is part of the 3M 268L and 366L family of fast cutting abrasives, so it is built to remove material efficiently while still holding a fine, uniform scratch pattern. This balance between cut rate and finish quality helps maintain predictable results across production runs.

Film Disc Details That Support Finishing Workflow

• The disc uses a premium micron graded mineral on high strength polyester film, which delivers controlled cutting while the tough film stands up to edge contact in regular abrasive disc applications.
• The 5 inch diameter with 5-hole pattern works with matching vacuum backup pads, allowing dust extraction paths that help keep the abrasive surface available longer during microfinishing passes.
• The disc is identified as 100 micron, placing it within the 180 through 15 micron range offered in this 3M series, so it fits into a clearly defined step between coarser and finer microfinishing grades.
• The 3M 268L family is described as fast cutting with a precise and consistent uniform finish, combining material removal with a repeatable scratch pattern across multiple parts.
• The product is sold in full box quantities only, which supports stocking a consistent abrasive for production lines or repeat finishing setups where the same disc is used frequently.

Hookit Film Disc Fit And Sanding Setup

This disc is a 5 inch 5-hole Hookit abrasive designed to interface with hook and loop style backup pads sized for 5 inch, 5-hole patterns. The Hookit attachment allows the polyester film-backed disc to sit flat on the pad, so the micron graded mineral can contact the work surface evenly. The 5-hole layout provides standard openings for systems that route dust extraction through the pad face. Because the abrasive is on a high strength polyester film, the disc maintains dimensional stability against the pad, supporting consistent contact pressure across the sanding area. The 100 micron grading positions the disc in a microfinishing sequence, so it can be selected as a specific step when setting up sanding workflows for uniform surface preparation.

Applying This 3M Microfinishing Disc In Workflows

Where This Abrasive Disc Fits In Finishing

This 3M microfinishing film disc fits best in applications where a precise and consistent uniform finish is required on workpieces. The premium micron graded mineral supplies a controlled scratch pattern, so surfaces progress predictably from coarser sanding toward finer preparation. The high strength polyester film backing lets the disc operate in environments where standard paper-backed abrasives might tear more easily, supporting steady work on edges and contours. With its 100 micron grade sitting within the broader 180 through 15 micron offering, the disc can be selected as a defined mid-step in a multi-stage finishing sequence. The 5 inch 5-hole format aligns with common 5 inch random-orbit style sanding setups that rely on dust paths through the face of the pad, so the disc integrates into existing tools designed for that diameter and pattern.

How Disc Design Supports Repeatable Sanding Results

The combination of premium micron graded mineral and polyester film backing supports repeatability by pairing sharp, uniformly sized abrasive particles with a stable substrate. This helps each disc cut in a predictable way from the first part to the last in a run. The Hookit attachment allows quick disc changes, so operators can move between different micron grades within the 180 through 15 micron range without lengthy downtime, keeping each step clearly defined. Being part of the 3M 268L and 366L family of fast cutting abrasives, the disc is built to remove material efficiently, which shortens time in each sanding stage while maintaining a uniform scratch profile. The 100 micron designation gives a concrete reference point in process sheets or work instructions, tying the physical disc to a specific finishing step and supporting consistent results across different shifts or operators.
