By combining two processes—drilling and reaming—into one tool, the AMAMCO Drill Reamer can save you both time and money, depending on your application. The Drill Reamer features the same core construction and available features as the AMAMCO Double Margin drill, but with the additional reaming diameters. We can configure the reaming step to cut on two or four flutes, for close-tolerance holes, high-quality surface finish, and reduced or eliminated exit burrs.
