3M Cubitron II 3in Fiber Disc 60 Grit 33391 High Performance Cutting

Description

Product Overview

The 3M Cubitron II 3 inch fiber disc is a premium abrasive solution designed for demanding industrial applications. Constructed with a hybrid ceramic abrasive core, the disc delivers superior cutting power while maintaining a consistent surface finish. The stiff fiber backing, reinforced with a strong resin bond, provides exceptional tear resistance, allowing the disc to withstand the rigors of high‑speed grinding without premature failure. With a 60 grit rating, the disc balances aggressive material removal with a smooth finish, making it suitable for both metal and painted surfaces. The disc measures 3 inches in diameter and 8 inches in thickness, offering a compact profile that fits a wide range of angle, bench, and die grinders. Its Roloc attachment system enables quick and secure mounting, reducing downtime between changes. The product carries the model number 33391 and complies with industrial safety standards, ensuring reliable performance in professional environments.

Usage

Designed for professional workshops, the Cubitron II fiber disc excels in a variety of settings where fast, efficient material removal is essential. Whether you are preparing metal components for welding, removing paint from automotive parts, or shaping wood in a cabinet shop, this disc provides the versatility needed to tackle diverse tasks. Its hybrid ceramic composition allows it to cut through hardened steel, aluminum, and other alloys with minimal effort, while the fiber backing ensures stability on the workpiece, reducing vibration and improving operator control. The disc’s 60 grit rating is ideal for medium‑coarse grinding, offering a balance between speed and surface quality. Because the disc is compatible with standard 3‑inch and 5‑inch grinding tools, it can be used on a range of equipment, from handheld angle grinders to bench‑mounted sanding stations. Proper safety equipment, such as eye protection and hearing protection, should be worn at all times, and the disc should be used in well‑ventilated areas to manage dust generated during operation.

FAQ

What types of materials can I use this disc on?

The Cubitron II fiber disc is suitable for a wide range of materials, including hardened steel, stainless steel, aluminum, brass, and painted surfaces. Its hybrid ceramic abrasive allows it to cut through tough alloys while the fiber backing provides stability on softer materials like wood and plastics, making it a versatile choice for many industrial tasks.

How does the Roloc attachment system improve workflow?

The Roloc system features a quick‑release mechanism that lets you attach and detach the disc with a simple twist. This design eliminates the need for additional tools, reduces the time spent changing discs, and ensures a secure fit that minimizes wobble during operation, thereby enhancing safety and efficiency.

Is this disc appropriate for continuous use in a production environment?

Yes, the disc is engineered for industrial and occupational use. Its robust construction, tear‑resistant fiber backing, and self‑fracturing abrasive grains are designed to withstand continuous operation, making it ideal for high‑volume production lines where reliability and longevity are critical.

Can I use this disc with a 5‑inch grinder?

While the product description focuses on the 3‑inch size, the Cubitron II line also offers a 5‑inch version with the same performance characteristics. If you require a larger diameter, be sure to select the appropriate SKU that matches the 5‑inch specification.

What safety precautions should I follow when using this disc?

Always wear appropriate personal protective equipment, including safety glasses, hearing protection, and a dust mask or respirator. Ensure the grinder is turned off before mounting or removing the disc, and verify that the disc is securely attached using the Roloc system. Operate the tool in a well‑ventilated area to manage dust, and avoid applying excessive pressure that could cause the disc to bind or break.
