3M 7010329874 | Scotch-Brite Hookit 5" Diameter 7447 PRO Very Fine Aluminum Oxide Pro Disc

Description

The 3M 7010329874 Scotch-Brite Hookit 7447 Pro disc is a 5" Hook & Loop non-woven pro disc engineered for consistent surface finishing and light paint removal. This very fine aluminum oxide abrasive disc delivers a uniform scratch pattern ideal for scuffing, blending and final surface prep on a variety of metals and plastics. The non-woven nylon construction resists tearing and loading, providing extended life over conventional abrasive discs in wet or dry operations. Hookit attachment enables fast, repeatable mounting on 3M hook-and-loop backup pads used with orbital sanders and backstands. Designed for controlled finish work, the disc reduces the risk of over-grinding while producing a clean, uniform texture on stainless steel. Water-resistant properties allow coolant or rinse cycles to extend abrasive life and reduce particulate buildup on the disc face. The Disc 5" diameter disc balances coverage and operator control for localized finishing, edge blending and selective material removal tasks. Maximum operating speeds align with common orbital tools, allowing safe, effective finishing at typical OPM ranges. This 3M 7447 pro disc is color-coded for quick identification on busy production floors, simplifying grade selection and process setup. Non-woven construction conforms to contoured surfaces for a consistent finish in radii and complex geometries without digging in. Use the 3M 7010329874 disc to lower rework rates by achieving repeatable surface outcomes across part lots and batches. The very fine grade is especially useful where a low-contrast finish is required prior to coating or plating operations. Durability and resistance to corrosion make the Scotch-Brite Hookit 7447 Pro disc suitable for environments prone to moisture and routine cleaning. Operators will appreciate the disc’s combination of flexibility, uniformity and quick-change convenience for high-mix finishing cells. When process control, longevity and finish consistency matter, the 3M 7010329874 delivers a professional-grade abrasive solution.

Product Features and Benefits

5" Hook & Loop Non-Woven Construction

The 5" Hook & Loop format of the 3M 7010329874 enables fast changes and consistent mounting on standard 3M Hookit backup pads.

Very Fine Aluminum Oxide Abrasive

The very fine aluminum oxide mineral provides a uniform scratch pattern for scuffing and light finishing using the Scotch-Brite Hookit 7447 Pro disc.

Durable, Water-Resistant Nylon Web

Non-woven nylon backing resists tearing and loading, allowing wet or dry use to extend the working life of the 3M 7447 disc.

Conformability For Contoured Surfaces

Flexible web construction conforms to radii and complex geometries, delivering consistent results on contoured parts and edge work.

Low Risk Of Over-Aggressiveness

The very fine grade reduces the chance of removing excess material while providing effective scuffing and surface preparation before coating.

Frequently Asked Questions

What is the 3M 7010329874 best used for?

The 3M 7010329874 Scotch-Brite Hookit 7447 Pro disc is ideal for cleaning, scuffing, finishing and light paint removal on metals and plastics.

Which attachment system does this disc use?

This disc uses the Hook & Loop Hookit attachment for quick mounting to 3M Hookit backup pads and orbital sander plates.

Can the 7447 pro disc be used on an orbital sander?

Yes, the 3M 7447 is suitable for orbital sander applications and pairs effectively with scotch brite pad for orbital sander setups used in finishing tasks.

Is this 5" disc suitable as an abrasive disc for metal finishing?

Yes, the very fine aluminum oxide and non-woven structure make it a reliable 3M abrasive disc for metal finishing and final surface prep.

How do I maintain or remove a PSA or Hook & Loop disc from my backing pad?

For Hook & Loop discs, peel from one edge and lift steadily; if adhesives or residue remain on the pad, clean the pad surface before reapplying a new disc, this is similar to the care used for other orbital sander scotch brite pads.
