End mills machine deep recesses and
grooves
Solid carbide miniature end-mill is particularly suitable for machining deep recesses and grooves and for shaping deep contours in precision componentsand moulds.
Hitachi Tool places considerable emphasis on research and development, and it is this company policy that has enabled Hitachi Tool to continuously generate innovative tool solutions, in particular to meet and anticipate the requirements of the tool and die and mould-making industries Constantly increasing costs in the field of tools and dies and mould-making make reduced cycle times and more efficient machining processes essential

Miniature end mill replaces EDM detailing
Solid carbide miniature end mill is for cutting deep ribs and the slotting in moulds, and also for machining deep corners and precision parts, normally done by EDM methods.
Ball end mill machines fine details, replaces EDM
Solid carbide miniature ball end mill has machines deep corners and precise details, as well as slots and ribs, which has conventionally been done with EDM methods.
In order to meet these requirements, Hitachi Tool has developed the new toric solid carbide EPDR Epoch Deep Radius miniature end-mill.
This tool is particularly suitable for machining deep recesses and grooves and for shaping deep contours in precision components.
Up to now, highly time-consuming EDM processes have been required for these operations.

Micro-fine grain carbide tools wear longer
Micro-fine grain solid carbide miniature tools with new cutting geometry and very small diameters provide a wear resistance in pre-hardened steels close to that of CBN tools.
Tools machine deep ribs, slots in 70HRC steel
Fine grain solid carbide miniature tools are specially suited to machining deep ribs and slots in moulds up to 70HRC - and for deep contours - up to 35xdiameter.
The EPDR Epoch Deep Radius provides the user with the rigidity required plus extended tool lifetimes to make complex routing operations of this kind economical and dependable.
This is equally true in high-speed machining operations.
These assets are, to a large extent, the product of Hitachi Tool's intensive development work in the field of tool and cutter geometry and coatings technology.
The completely new design of joint-neck tool shank on the EPDR Epoch Deep Radius and its optimised length considerably reduce the risk of tool breakage and also minimise vibrations.
Add to this the redesigned geometry of the cutters and cutting edges, which have a noticeable stabilising effect on the end-mill, particularly when performing cutting operations in deep moulds.
In addition, these end-mills are already provided with the Hitachi TH45+ NANO PVD coating.
This new coating, which has already been successfully used in practice, enables much extended tool service life when machining hardened materials, in particular during dry-cutting.
A further special feature of the EPDR Epoch Deep Radius is the increased effective length of the using length, which comes into its own when dealing with an existing draft.
Example: When machining a workpiece with a draft of 1 deg using a 0.5mm radius end-mill and an effective length of 10mm, the EPDR Epoch Deep Radius provides a using length of 12.03mm.
Conventional geometries, on the other hand, only provide a length of 10.8mm.
EPDR Epoch Deep Radius Tool type - toric solid carbide miniature end-mill: * Material - microscopic fine-grained substrate.
* Corner radius tolerance - 0.01mm.
* Dimensions - 0.2mm diameter (corner radius 0.05mm) to 3mm diameter (corner radius 0.5mm).
* Effective length - up to 20xD.
For example: 1.0mm diameter available in seven different effective lengths from 4x to 20xD and a corner radius of 0.2mm.
