TCT annular cutter serves in various fields, such as construction, mining, shipbuilding, engineering, and railway. It cuts fast and clean holes in hard metal materials including mild steel, structure steel, and cast iron. Konetool supplies both HSS annular cutters and TCT annular bits at cost-efficient prices. Our TCT annular cutters are made from premium micro-grain tungsten carbide and fine alloy steel, resulting in less damage to tips and better longevity.

Compared with high-speed steel or cobalt core drill bits, carbide mag drill bit drills faster and lasts longer. The carbide teeth of TCT slugger bits feature better wear resistance and heat resistance and maintain the hardness longer, so the TCT annular drill bits can process hardened materials and create larger holes. Besides, TCT annular cutter bits are less likely to break than HSS annular cutters, if used properly.

Konetool provides mag drill bits of various shanks. Weldon shank and Univeral shank( Nitto shank) are always available as our normal orders; Fein quick-IN shank, threaded shank, and parallel shank are available as a customization order. Thus our slugger bits fit various types of magnetic drills, such as Alfratool (Rix), Hougen, Jancy, Euroboor, BDS, Ruko, Rotabroach, Evolution, Magtron, G&J Hall, Powerbor, Unibor, Fein, JEI, and Nitto. Konetool TCT annular cutters are compatible with slugger drills, drill presses, hand-held drills, and milling machines. Using broach drill bits with a drill press or milling machine requires a shank arbor.
