These completely unique CarbideMax TCT Annular cutters are for the most extreme drilling depths through thick metal, box sections or stacked plate. The CarbideMax 200mm Broach Cutterhas precision drilling flutes and a specially engineered geometry for accurate cutting. These cutters come with a standard 19.05mm Weldon shank for use in any magnet drill with sufficent stroke. HMT CarbideMax TCT Broach cutters are tipped with individually brazed cutting teeth of the highest quality tungsten carbide. They are designed with an elaborate cutting geometry which results in faster, quieter, easier drilling and chatter free performance. Furthermore, because the teeth of the cutter are doing all of the hard work, less strain is put on the wall of the cutter. Therefore the thinner wall means less metal is removed, giving a faster cut.
