Standard Abrasives A/O Spiral Band 704731, 3/4 in x 1 in 60, 100 ea/Case

• Aluminum oxide mineral is friable and breaks down to reveal sharp cutting edges for a consistent cut
• No tools required for band changes
• Single ply abrasive is flexible and tensile, conforming to flat and contoured surfaces
• Spiral band easily fits over rubber drums
• Spiral construction helps eliminate shadow marks and chatter

Standard Abrasives Aluminum Oxide Spiral Band is a tensile yet strong abrasive – great for light finishing, polishing, blending and deburring on both hard and soft metals.

Recommended Applications
Standard Abrasives™ Aluminum Oxide Spiral Band is the best product for polishing and blending flat surfaces and contours, because its spiral shape enables it to smoothly roll over these surfaces. The circular band rotates centrifugally as you move it around the workpiece and – given its small size – the abrasive can easily fit inside hard-to-reach areas. Standard Abrasives™ Aluminum Oxide Spiral Band is great for removing parting lines, tiny imperfections and little burrs, which could otherwise be difficult to remove with a larger abrasive disc or wheel.

Special Features
The spiral construction on Standard Abrasives™ Aluminum Oxide Spiral Band eliminates shadow marks and chatter. Aluminum oxide mineral cuts sharp but is still friable, fragmenting under heat and pressure to reveal sharp cutting edges, so you get a consistent cut throughout the life of the abrasive. Available in grades 24 to 320 grit, you can choose the right grade for your project, depending how aggressive a scratch you desire. Coarser grades, like 24, are good for heavy stock removal, whereas finer grades, like 320, are good for metal finishing and polishing.

Tips for Optimal Use
Standard Abrasives™ Spiral Bands are intended for use with rubber drums. The single ply or "single thickness" abrasive fits snugly around the drum like a glove. Compared to 2- or 3-ply thicknesses, the single ply is a bit more flexible and conformable, which makes it a good match for contoured surfaces. It is important for both the drum and the abrasive to have the same nominal diameter to prevent skipping and bumping.

Rather than deflecting or skidding over the substrate, the Spiral Band stays in constant contact with the workpiece to swiftly rid the surface of little burrs. The maximum allowable RPM for spiral bands is the same as the maximum RPM of the drum, provided the drum and band have the same nominal diameter. Typically, the rubber drum attaches to portable drills, die grinders, straight shaft and angle grinders. The great news is, the drum requires no extra tools for band changes.

Removing contaminants from flat and contoured surfaces is smooth – in finish and operation.

Standard Abrasives Brand Model

The Standard Abrasives A/O Spiral Band 704731 offers reliable performance with its aluminum oxide mineral. This abrasive breaks down to reveal sharp cutting edges, ensuring a consistent cut throughout its use. The brand’s reputation is backed by quality and durability in abrasive products.

Precise Dimensions And Size

This product measures 3/4 inch by 1 inch, providing a compact size that fits well in tight or hard-to-reach areas. Its small dimensions allow for detailed work on flat and contoured surfaces without sacrificing control or effectiveness.

The spiral band’s size also helps it rotate centrifugally, rolling smoothly over surfaces to remove parting lines, tiny imperfections, and burrs. This makes it a practical choice for precision tasks requiring careful attention to detail.

Flexible Single Ply Format

The single ply abrasive construction is flexible and tensile, conforming easily to both flat and contoured surfaces. This flexibility ensures consistent contact with the workpiece, improving the quality of polishing and blending operations.

Compared to thicker abrasives, the single ply format fits snugly around rubber drums without tools, simplifying band changes. This ease of use saves time and effort during projects, especially when working with complex shapes.

Wide Grade Range Options

Available in grades from 24 to 320 grit, this spiral band lets you choose the right level of abrasiveness for your project. Coarser grades like 24 are suitable for heavy stock removal, while finer grades like 320 excel at metal finishing and polishing.

This range ensures you can tailor the abrasive’s aggressiveness to your needs, whether removing burrs or achieving a polished finish. The 100 pieces per case provide ample supply for multiple applications or extended use.

Pack Count And Compatibility

The pack includes 100 spiral bands, making it a cost-effective choice for workshops or production environments. Having a large quantity on hand means you can maintain productivity without frequent reordering.

These bands are designed to fit rubber drums used with portable drills, die grinders, and angle grinders. Their spiral construction helps eliminate shadow marks and chatter, ensuring a smooth finish on every job.
