3M Cubitron II Stikit Film Disc 775L Sanding Disc Fast Cut

Description

Product Overview

Designed for demanding industrial sanding tasks, the 3M Cubitron II Stikit Film Disc 775L combines the brand’s patented Precision Shaped Grain technology with a resilient film backing. The disc measures 5 inches by 5 inches and is only 0.04 inches thick, delivering a lightweight yet robust solution that fits standard 5‑in PSA sanders. Its 80‑220 micron abrasive grit range provides flexibility for both aggressive stock removal and finer finish work, making it suitable for a wide variety of substrates including wood, metal, plastics, and composites.

Revolutionary 3M Precision Shaped Grain technology creates a uniform, sharp cutting edge that removes material up to two times faster than conventional abrasives. The film backing adds exceptional tear resistance, preventing premature disc breakage and extending edge life even under heavy load. This combination of speed and durability reduces downtime caused by frequent disc changes, allowing operators to maintain consistent workflow and achieve smoother surface finishes with fewer passes.
The Stikit attachment system simplifies disc changes, enabling quick and tool‑free swapping that saves valuable time on the shop floor. Each pack contains fifteen discs, providing ample inventory for high‑volume production lines while keeping storage requirements low. The discs are manufactured for industrial and occupational use only, ensuring they meet rigorous performance standards required by professional sanders and finishing specialists.
Key specifications include a product dimension of 5 × 5 × 0.04 inches, a weight of 4.2 ounces, and a model number 87337. First released on June 23 2018, the disc has earned a strong reputation reflected in a 4.7‑star rating from 40 customer reviews and a best‑sellers rank of #51 in the Power Sander PSA Discs category. These metrics demonstrate the disc’s popularity among professionals seeking reliable, high‑performance sanding solutions.
Manufactured in 3M’s state‑of‑the‑art facilities, each disc undergoes a multi‑stage coating process that bonds the abrasive grains to the film substrate with precision. The result is a uniform abrasive surface that resists clogging and maintains consistent performance across the entire disc area. This uniformity is critical when working on large panels, as it prevents uneven wear and ensures that the finish quality remains high from start to finish.
The disc’s compact size and low weight make it ideal for handheld sanders, orbital sanders, and belt sanders that accept 5‑in PSA discs. Its design also accommodates high‑speed rotary applications, delivering reliable performance at speeds up to 12,000 RPM. Whether used in a production line or a small workshop, the disc’s versatility and durability provide a cost‑effective solution that reduces the need for multiple disc types.

Usage

Professionals in woodworking, metal fabrication, and composite manufacturing rely on the Cubitron II Stikit Film Disc to accelerate material removal while preserving surface integrity. The disc’s aggressive cutting action is ideal for shaping rough stock, removing paint, rust, and weld spatter, or preparing surfaces for subsequent finishing operations. Its ability to maintain a consistent cut across a range of grit sizes ensures that users can transition seamlessly from heavy‑stock removal to finer sanding without changing tools.

In automotive repair shops, the disc excels at deburring engine components, smoothing body panels, and refining interior trim pieces. Its film backing resists tearing even when applied to hard alloys, reducing the risk of disc fragments contaminating the workpiece. For aerospace applications, the disc’s precision‑shaped grain delivers the fine control needed to meet strict tolerance requirements while minimizing material waste.
The disc is also well suited for maintenance tasks in facilities management, such as refurbishing flooring, cleaning concrete surfaces, or preparing metal handrails for repainting. Its compatibility with standard 5‑in PSA sanders means it can be deployed across a wide range of equipment without additional adapters, simplifying inventory management for large organizations. By delivering fast, consistent results, the Cubitron II Stikit Film Disc helps reduce labor costs and improve overall project timelines.
In paint removal projects, the disc’s aggressive cutting action quickly strips old coatings without damaging the underlying material, making it a preferred choice for refinishing furniture and automotive panels. The film backing’s resistance to tearing ensures that the disc remains intact even when encountering stubborn layers, reducing the risk of debris embedding in the surface.
For precision finishing tasks, such as preparing aerospace composite panels for bonding, the disc’s fine grit options enable controlled material removal while preserving surface tolerances. Operators can achieve a smooth, uniform finish that meets strict industry standards, reducing the need for additional polishing steps.
