Replaceable head drill TTD

The outstanding cost-effectiveness with consistently high stability and precision of the TTD replaceable head drills is achieved through the minimised use of carbide metal. As far as the cutting values and drilling results are concerned, the performance and quality level is absolutely on a par with that of comparable solid carbide drills. The central element here is the unique TTS (Torque Transfer System) connection. Thanks to its special design, it allows very high changing and radial run-out accuracies, high drilling parameters and optimum torque transfer values.

The holder system enables drilling depths of 1xD, 3xD, 5xD, 8xD and 12xD to be achieved. The drill heads are available in the diameter range from 12-45 mm from stock.
