Description

Replaceable head tool systems are now indispensable in modern production. Increasing raw material prices, lean inventories and the consideration of life cycle costs as against the pure purchase price favour the usage of replaceable head systems. MAPAL has placed on the market highly productive systems for all application areas; systems that are in no way inferior to monolithic tools – quite the opposite. With a focus on highly precise, very stable connections it has been possible to limit the usage of expensive carbide to the tool head, and to make the machining stable and precise overall. Cutting edge geometries and coatings optimally matched to the workpiece material to be machined achieve the best results without compromises in relation to solid carbide drills. In the area of drilling from solid, MAPAL offers the replaceable head drill TTD and insert drill QTD. At the centre are the TTS connection on the TTD and QTS on the QTD that permit optimal torque transfer and at the same time achieve high changeover and radial run-out accuracies. In this way the replaceable head drills achieve the performance of a solid carbide drill at lower cost and with simple handling. The latest manufacturing technologies, such as additive manufacturing, make it possible to manufacture the QTD already from a diameter of 8 mm with internal cooling.
