Overview

Designed for deburring and chambering larger holes, this Brownells tool fills the gap when broaches are not the right fit. It is suited to shop work where a clean, controlled finish on oversized openings is needed. The focus is on practical utility rather than broad versatility, so it is best considered a purpose-built addition to a gunsmithing or maintenance setup.
