What does "VFN" stand for on the product description?
"VFN" stands for Very Fine Grade Abrasive. This grade provides finer finishes while still providing an aggressive cut to remove defects efficiently.
Is it easy to change out these discs when working with them repeatedly throughout a job?
The Easy-to-Use system speeds up process time by allowing you to attach or remove abrasive quickly.
Yes, thanks to its convenient hook-and-loop backing system (Hookit), this disc makes attachment and removal quick and easy during repeated use.
The 7447 PRO Disc is designed to reduce surface preparation time, whether it's for painting in the automotive industry or scuff sanding furniture or cabinetry. The fiber coating technology of the Scotch-Brite™ Hookit™ 7447 PRO Disc allows it to cut faster and produce a more consistent scratch, reducing the time it takes to scuff, prep, or finish parts. The tightly graded abrasive particles provide consistent, uniform results throughout the life of the disc. This disc features very fine grade aluminum oxide abrasives that cut fast, leaving a clean and smoothly finished surface.Versatile Disc Replaces Steel Wool
The Scotch-Brite™ Hookit™ 7447 PRO Disc is suitable for use on a wide variety of materials such as wood, metal, plastics, ceramics, porcelain, glass, rubber, or composites. The performance of this pad is comparable to steel wool grade 1. However, unlike steel wool, the Scotch-Brite™ Hookit™ 7447 PRO Disc won't rust after use or create fine metal splinters. Use it for cleaning, finishing, blending, and deburring, or for scuffing before applying paint and paint primers. It can even clean upholstery and chrome. This versatile product is effective in wet or dry environments and can be rinsed and used over and over again.The Scotch-Brite™ PRO Advantage
Scotch-Brite™ PRO is a unique surface conditioning product with abrasives incorporated into non-woven nylon fibers. The breakthrough fiber coating technology allows Scotch-Brite™ PRO abrasive products to cut faster and produce a more consistent scratch than competitive non-woven abrasive products, reducing the time and effort it takes to finish parts. Combining abrasives with the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers.Fast Cut and Durability of Aluminum Oxide
Aluminum oxide is a popular mineral among industrial professionals because of its cut-rate and long life. It is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.The Convenience of 3M™ Hookit™
The Hookit™ backing on the 7447 PRO disc allows easy, direct attachment of the disc onto a 3M™ Hookit™ Backup Pad (sold separately), eliminating the need for an intermediary Conversion Face between the non-woven disc and the backup pad. Hookit™ discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and be used again and again for the extent of the abrasive life. Direct attachment makes using the popular 7447 PRO disc more convenient than ever. Rather than working with a hand pad or needing to incorporate a Conversion Face to drive the disc, operators can increase productivity and make the most of the disc by running it on a 3M™ Orbital or Random Orbital Sander.
