Cubitron II Cloth Band 341D, 3′ Diameter x 3′ Width, 80 Grit, Brown (Pack of 50)

Description

Product Overview

The 3M Cubitron II Cloth Band 341D is engineered to meet the demanding requirements of modern manufacturing, maintenance, and repair environments. Constructed with a high‑quality X‑weight cloth backing, the band resists deformation under heavy sanding and grinding loads, ensuring a stable contact surface that maximizes material removal efficiency. The abrasive component consists of tough aluminum oxide mineral particles sized to an 80 grit rating, delivering a balanced blend of cutting speed and surface finish that works well on metals, plastics, composites, and wood. Each band measures a 3‑foot (approximately 91 cm) diameter and a 3‑foot width, providing ample coverage for large surface areas while maintaining flexibility to conform to both inner and outer contours of complex parts. The resin bond that secures the abrasive grains to the cloth is formulated to withstand high temperatures and pressure, allowing the band to perform consistently even in prolonged operation or when used with high‑speed rotary tools. Packaged in a convenient case of 50 bands, the product offers a cost‑effective solution for shops that require reliable, repeatable results across a variety of abrasive applications.

Usage

This cloth band is intended for use with a rubber expander wheel attachment, which is sold separately, and can be mounted on standard die grinders, rotary drills, or other compatible rotary power tools. The flexible tube‑shaped design enables the band to wrap around the expander wheel, creating a smooth, continuous abrasive surface that follows the geometry of the workpiece. Ideal for deburring sharp edges, removing parting lines, and smoothing imperfections, the band excels in applications such as aerospace component finishing, automotive part refurbishment, metal fabrication, and general maintenance of equipment. Its ability to handle both inner and outer surfaces makes it suitable for cleaning the interior of cylindrical housings, pipe sections, and gear teeth, as well as for finishing exterior surfaces like brackets, panels, and frames. Operators benefit from reduced hand fatigue due to the band’s balanced weight distribution and the low vibration characteristics of the cloth backing, allowing for longer work periods without compromising precision or safety.

FAQ

What types of materials can I use this band on?

The 3M Cubitron II Cloth Band 341D works well on metals such as steel, aluminum, and stainless steel, as well as on non‑metallic materials like plastics, composites, and wood. Its 80 grit aluminum oxide abrasive offers a versatile cutting action that balances speed and surface finish across these diverse material families.

Can the band be used with a standard die grinder without additional accessories?

Yes, the band is designed to fit a rubber expander wheel attachment that can be mounted on most standard die grinders and rotary drills. The expander wheel is sold separately, but once installed, the band provides a seamless abrasive surface that works with the existing power tool.

How do I maintain the band for optimal performance?

To keep the band performing at its best, regularly inspect the cloth backing for signs of wear or tearing and replace the band when the abrasive surface becomes glazed. Clean the band after each use to remove accumulated dust and debris, and store it in a dry environment to prevent moisture absorption that could affect the resin bond.

Is the band suitable for high‑speed applications?

Absolutely. The resin bond and cloth backing are engineered to tolerate the heat generated by high‑speed rotary tools. This allows the band to maintain its abrasive efficiency and structural integrity even when operating at elevated RPMs, making it ideal for fast material removal tasks.

What warranty does 3M provide for this product?

3M offers a limited warranty that covers manufacturing defects in materials and workmanship. If a band fails due to a defect within the warranty period, 3M will replace the affected item at no cost, reinforcing the company’s commitment to quality and customer satisfaction.
