3M 7010512863 Spiral Band 120 Grit Fine 3/8 X 1/2 Inch

Product Description

The 3M 7010512863 is a coated abrasive spiral band designed for use with spiral band drums on portable or bench-mounted sanders. It measures 3/8 inches in diameter by 1/2 inches wide and is constructed with an aluminum oxide abrasive bonded to a heavy-duty X-weight cloth backing. Rated at 120 grit, this band falls in the fine grade range, making it well-suited for light material removal, surface blending, and finishing passes on wood, metal, and composites. The cloth backing provides flexibility and durability through repeated use cycles. Machinists, woodworkers, metalworkers, and maintenance technicians typically use this type of band for contour sanding and deburring tasks where precision fit and consistent finish are required.

This spiral band is intended for use in applications requiring fine-grit abrasion on curved, contoured, or hard-to-reach surfaces. It is commonly used in production and maintenance environments for deburring metal parts, shaping wood components, and smoothing weld areas. The compact 3/8-inch diameter allows it to fit tightly inside bores, slots, and irregular profiles. It is sold individually per package with a minimum order quantity of 100 units, making it appropriate for shops that require ongoing abrasive stock.

Key Features

• 120 grit aluminum oxide abrasive for fine-grade stock removal and surface finishing
• X-weight cloth backing delivers durability and flexibility on contoured surfaces
• 3/8-inch diameter fits standard spiral band drum mandrels for portable and bench sanders
• 1/2-inch width provides a stable contact area for consistent material removal
• Coated abrasive construction resists loading on wood and soft metals

Compatibility

Designed as an OEM-style replacement or stock abrasive consumable for use with spiral band drum mandrels sized for 3/8-inch diameter spiral bands on portable sanders and bench-mounted drum sanding units.

Installation Notes

Installation is typically performed by machinists, metalworkers, or woodworking professionals. Before mounting, power down and disconnect or lock out the sander per OSHA lockout/tagout procedures. Slide the spiral band onto the appropriate drum mandrel and confirm it is fully seated before resuming operation. Inspect the band for tears or excessive wear before each use and replace when abrasive material shows significant depletion.
