Welcome to the online home of CMB Master-Sand, your source for quality replacement sanding brushes and complete profile sanding systems.

Please bear with us; we're in the process of giving you more of the information you need from our website. During this time, some content may be temporarily unavailable.

We manufacture a full line of abrasive brushes to fit most machinery in use today, as well as brush sanding cores for OEMs and machinery builders.

Our products have been original equipment on some of the world's finest brush sanding machinery since 2006. See for yourself why the Master-Sand system is simply the best value in brush sanding, and is the only brush sanding system manufactured in the United States of America.

The Master-Sand system has already been imitated, but has never been equaled.
