This exceptional annular cutter from Champion Cutting Tool is designed for precision drilling in steel plates, structural beams, pipes, and tubes, offering an impressive ability to drill large diameter holes with ease. Constructed from surface-treated high-speed steel, it ensures rapid cutting while providing enhanced durability for extended tool life, particularly when used with BruteLube fluid or wax for increased heat resistance. Capable of achieving a depth of cut up to one inch, the cutter features a 3/4-inch flatted shank, making it compatible with RotoBrute magnetic drill press systems and most other magnetic drill setups. For added efficiency, pairing it with the XL100P pilot pin (available separately) allows for quick ejection of metal plugs, maximizing productivity during your drilling tasks.
