The AMAMCO Drill/Drill Reamer is great for applications in which a third step is necessary, such as those with diverse materials in various stacks. The Drill/Drill Reamer features double margin construction for stability in the bushing and hole, a second drilling step to share the chip load, and a final reaming step to produce a close tolerance hole with great surface finish and minimal to no exit burr.

The Drill/Drill Reamer's core construction follows the same quality pattern as the AMAMCO Double Margin Drill. Like other advanced drills, AMAMCO can manufacture the Drill/Drill Reamer with customized geometries from point to the end of the shank, to address the specific demands of your application.
