Replaceable head tool systems have become an indispensable part of modern manufacturing. After all, increasing raw material prices, streamlining of warehouses and consideration of life cycle costs are reason enough.
Our two replaceable head systems, the TTD replaceable head drill and the EXD indexable insert drill, are highly productive and are not inferior to monolithic tools in any way – on the contrary.
Our focus during development was on highly precise, very stable connections that enable optimum torque transfer while achieving high change and radial run-out accuracy. Our replaceable head drills thus operate on the performance level of a solid carbide drill – at lower costs and with simple handling.
The latest manufacturing technologies such as additive manufacturing make it possible to produce the EXD from a diameter as small as 8.00 mm with interior cooling.
Excellent chip formation and reliable chip removal are the key features of the EXD indexable insert drill.
Numerous indexable insert changes per tool holder are possible because the basic holder is not washed out.
The insert connection has a particularly simple, effective construction. A bolt routed laterally through the indexable insert stably clamps the indexable insert in the prismatic holder. The tool achieves high cutting data and bore quality as a result.
We produce holders for diameters ranging from 8 mm to less than 13 mm with the aid of additive manufacturing. This method makes it possible to manufacture these small tool bodies with spiral cooling channels. Compared with the central coolant supply with deflections, it allows us to increase the coolant flow by 100%, specifically thanks to the cooling channel profiles that deviate from a circular form.
