High Machining Speeds

Gerardi's Evolution Line angle heads feature an interchangeable Drive Taper which enables the same angle head to be used of different machines (e.g. BT or SK) simply by changing the input shaft.

ATC Series

Designed 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.

ATC 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.

ATC SLIM Series

Ideal for micro-machining in narrow spaces.

ATC F90 Series

Ideal for milling, drilling, tapping
at ±90.

ATC F90L Series

Long series for deep machining applications.

ATC F90 10BAR Series

Coolant input from positioning pin and output through the tool.

ATC FR90 70BAR Series

Offset series for machining in
narrow spaces.

ATC FMU Series

Adjustable output at ±90° for tilt drilling, milling and tapping.

CMTC F90S Series

8.000RPM high speed angle head
with exceptional performance.

MTC F900L Series

High torque angle head for heavy
duty machining.
