Increased MRR equals bottom-line savings to customers in throughput, machine time, and personnel hours. The TDD1 Z Series in the WU20PD grade offers secure and consistent performance, excellent hole quality, and reduced cycle times. The standard lines are available from 3 to 13mm and lengths of 15, 20, 25, and 30 x D. It eliminates the traditional HSS or gun drilling without pecking, at up to 100% increased penetration rates. 132° TDS Point Geometry Low thrust. Excellent centring capabilities.
