3M 7000139536 Spiral Band 80 Grit Aluminum Oxide

Product Description

The 3M 7000139536 is a coated abrasive spiral band designed for use with spindle sanders and drum sanding attachments in metalworking, woodworking, and finishing applications. Built on a heavy cloth backing with an X-weight designation, this band delivers consistent stock removal at 80 grit, which falls in the medium grade range. The aluminum oxide abrasive material provides durable cutting action across a range of surfaces including ferrous metals, hardwoods, and composites. At 1.5 inches in diameter and 1 inch wide, it fits standard spiral band spindle configurations. This product is sold individually per package and is intended for professional shop and trade use.

This spiral band is suited for interior contour sanding, deburring, and surface blending on parts that require controlled material removal. It performs well in production environments where consistent finish quality is needed across repeated passes. The 80 grit medium grade makes it appropriate for intermediate stock removal before transitioning to finer grits for final finishing. Typical users include machinists, fabricators, woodworkers, and finishing technicians working with stationary or portable spindle sanding equipment.

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive band for spindle sanders and drum sanding tools that accept 1.5 inch diameter by 1 inch wide spiral bands.

Installation Notes

Installation is performed by machinists, woodworkers, or finishing technicians during routine abrasive changeover on spindle sanding equipment. Always power down and disconnect the machine from its power source before removing or mounting abrasive bands. Ensure the spindle diameter matches the band inside diameter to prevent slippage or uneven wear during operation. Inspect the spindle drum for wear or damage before mounting a new band.
