DESCRIPTION
A Rotabroach type annular mag broach drilling bit—commonly called an annular cutter—is a precision-engineered cutting tool designed for use with magnetic drilling machines (mag drills). Unlike traditional twist drills, annular cutters remove only the periphery of the hole, leaving a solid slug, which makes hole cutting faster, cleaner, and more energy-efficient. Rotabroach, a pioneering UK manufacturer, is synonymous worldwide with high-performance annular cutters used in fabrication, construction, railways, and heavy engineering.
