Excellent surface quality and higher metal removal rates

The unique design allows to apply the tool in multiple passes, called “step down”.

Most tools leave tool marks with every pass they take, resulting in unsatisfactory or low-quality wall finishes. This usually requires another finishing pass at the very end of the process.

Mill 4-15 eliminates that finishing pass with an additional tool, saving time and money.

Part of the First Choice Program.

Easy to select, easy to order, easy to apply, exceptional performance.
