Annular cutting tools are a specialized cutting tool used for drilling precise, clean holes in metal. They are often referred to as Rotabroaches. Unlike traditional twist drills, it only cuts the outer edge of the hole, leaving a solid slug at the center. This design results in faster drilling, less material waste, and smoother finishes. Annular cutters are commonly used with magnetic base drills and are ideal for structural steel, pipe, and heavy fabrication work. This annular cutter set is made from high-speed steel (HSS), offering excellent durability, heat resistance, and cutting performance across a wide range of materials.
