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
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.
