Annular Cutters

Our annular cutters or magnetic drills are designed to be used in magnetic frame drill used for drilling out heavy-duty truck frames and structural steel. They are made from M42 super cobalt steel which is the best cobalt steel on the market made from molybdenum-chromium vanadium tungsten with 8% cobalt which provides superior red hot hardness and resistance to wear over other cobalt and conventional high-speed steel. They can cut on curved surfaces, overlap cuts on existing holes, stay sharp much longer than other cutting tools, and leave a burr-free hole. They are made for cutting a 2" deep hole. Made in England by Norseman Drill & Tool.
