3M 7000120781 Non-woven Abrasive Roll 4 in X 30 Ft Medium

Product Description

The 3M 7000120781 is a non-woven abrasive roll constructed with aluminum oxide abrasive mineral on a flexible, non-woven fiber substrate. Measuring 4 inches wide and 30 feet long, this roll provides a continuous supply of abrasive material that can be cut to length as the job requires. The medium grade makes it suited for general-purpose surface conditioning, blending, and finishing on metal, wood, and composite surfaces. Fabricators, pipefitters, HVAC sheet metal workers, and maintenance technicians keep rolls like this on hand for consistent scratch patterns and controlled material removal without aggressive stock loss.

This non-woven roll is commonly used in light deburring, surface prep before coating or welding, oxide removal, and weld blending applications. The flexible non-woven construction conforms to contoured and irregular surfaces better than rigid abrasive products. It is appropriate for both bench and hand applications in fabrication shops, mechanical rooms, and field service environments. The purple color coding identifies the medium grade for quick identification in multi-grade shops.

Key Features

• Aluminum oxide abrasive mineral for consistent cutting action on ferrous and non-ferrous metals
• Medium grade provides a balance between material removal and surface finish
• 4-inch width suits standard hand pads, backup rolls, and inline tool arbors
• 30-foot length allows the roll to be cut to any required length, reducing waste
• Non-woven construction conforms to contoured and irregular surfaces
• Purple color coding for fast grade identification in multi-grade inventories

Compatibility

Designed for use with standard 4-inch non-woven roll holders, inline finishing tools, and backup pads accepting 4-inch wide abrasive roll stock. Suitable for hand-applied surface conditioning and machine-assisted finishing operations.

Installation Notes

Cut to desired length using snips or a utility knife before mounting on a roll holder or backup arbor. Secure all workpieces before applying abrasive contact, and wear appropriate eye and hand protection per applicable shop safety standards. When used on power tools, confirm the tool RPM rating does not exceed the abrasive roll specification. Dispose of spent abrasive material in accordance with local waste regulations, particularly when working with coated or treated base metals.
