ATC series

ATC angle heads are ideal for CNC machines with automatic tool change and can be automatically transferred from the tool store to the machine spindle and vice-versa.

The orientation ring and arrester arm support ring are both 360° adjustable to allow the best angular orientation. On FMU heads, the cutter spindle housing can be adjusted at ±90°.

MTC series

This range of angle heads is for conventional machines without automatic tool change.

MTC angle heads (Manual Tool Change) are manually mounted on the machine headstock through a flange.

On FMU heads, the cutter spindle housing can be adjusted at ±90°.

Main shaft with interchangeable Drive Taper (Double contact) allows an EVOLUTION angle head to be used on other machining centres with different spindle types and sizes. It is also possible to exchange the anti-rotation (arrester) sub-assembly and the input drive taper with no effect on rigidity or accuracy.


Case hardened and ground


with automatic release and Internal coolant through the pin.


Up to 10 bar coolant through the pin included in the standard heads. Options include feeding coolant at 10 bar through the cutter spindle or at up to 70 bar through the machine.


Composed by pin group, ring and shank group


Treated steel head body with 360° positions and internal air pressure, maximum rigidity and corrosion resistant.

Minimum thermal expansion.
