YOUR FINISHING PROCESS JUST GOT EASIER. DISCOVER HOW OUR TOOLS HELP THE AUTOMOTIVE AFTERMARKET AND REBUILDING INDUSTY

OVERVIEW

The automotive aftermarket and rebuilding business; a multibillion dollar industry, is one of the largest sectors in the world. This market continues to grow due to the increased desire to extended vehicle life with cost-effective repairs. The U.S. automotive aftermarket alone is exceeded approximately $400 billion, with a large part devoted to remanufacturing and repairing of critical engine components.

The automotive industry needs accurate surface finishing to rebuild and restore engine parts, brake systems, and other critical components to return vehicles to perform like new. Metalworking professionals and automotive hobbyists benefit from using industrial brushes and specialized tools like the FLEX-HONE® to achieve superior surface conditioning, deburring, and crosshatching. Both industrial brushes and the FLEX-HONE® tool offer specialized, efficient, accurate finishing solutions that guarantee high-quality results for all of your projects. The use of these tools enhances productivity, cuts costs, and enhances overall performance of rebuilt automotive components.
