Master 40 PPI flat and 40 PPI matched fits, advanced machine scraping, and finish work to a true 40-point standard.
In-Plant
We bring the class to your floor and tailor it to your machines, your tolerances, and your crew’s schedule.

Hand vs. BIAX power
The foundation of feel and control. Pull and push scrapers for fine finishing, frosting, and the matched fits a machine can’t do for you.
