Achieve maximum rigidity and extreme drilling accuracy with GARANT Micro & Short Drill Chucks MAS-BT. Engineered for CNC milling machines and machining centers operating with MAS 403 / JIS B 6339 (BT) steep taper spindles, these high-precision short drill chucks integrate the shank and chuck into a single monoblock housing. By eliminating intermediate adapters, the ultra-short overhang design maximizes system stiffness, reduces radial runout, and prevents drill slippage under heavy torque, making them ideal for precise micro-drilling, counterboring, and production drilling applications.
