3M 7010508238 Spiral Band 180 Grit 3/8 X 1/2 Inch

Product Description

The 3M 7010508238 is a coated abrasive spiral band designed for use with pneumatic drum sanders and rotary finishing tools. It features aluminum oxide abrasive on a cloth backing, rated at 180 grit in the very fine grade range. This combination delivers controlled material removal and surface refinement on metal, wood, and composite materials. The cloth backing provides flexibility and durability under the lateral stress typical of spiral band operation. Machinists, fabricators, and finishing technicians use this band for deburring, blending, and final-pass surface prep work.

This spiral band is suited for light deburring, contour sanding, and surface finishing in both shop and field environments. The 3/8 inch diameter and 1/2 inch width make it appropriate for tight-radius internal surfaces, tube interiors, and bore edges where flat abrasives cannot reach. It is commonly used in metalworking, woodworking, and general fabrication applications requiring a consistent very fine finish. Each package contains one band, with a minimum order quantity of 100 units.

Key Features

• Aluminum oxide abrasive delivers consistent cutting action across metal and wood surfaces
• 180 grit very fine grade for surface refinement and light material removal
• Cloth backing provides flexibility and resistance to tearing during contour work
• 3/8 inch diameter fits standard small-diameter spiral band mandrels
• 1/2 inch width suited for tight-access bore and contour sanding applications

Compatibility

Designed as an OEM-style replacement spiral band for use with standard pneumatic and electric drum sander mandrels accepting 3/8 inch diameter spiral bands.

Installation Notes

Installation is performed by trades and technicians using pneumatic or electric rotary tools fitted with a compatible mandrel. Ensure the tool is fully powered off and disconnected from the air supply or power source before changing bands. Seat the spiral band fully onto the mandrel before operation to prevent slippage or uneven wear. Eye protection is required during abrasive operations per standard shop safety practice.
