Recessing attachments are usually used to machine internal grooves or recesses

Available in three versions:

-Heads for thrust recesses: the recess head fits into drillholder and is pushed by a “shelf” mounted on the cross slide.

-Fixed ramp recesses: the recessing device is installed on the central support and actioned by the motion of the central support or independent pusher. 

-Rotating ramp recesses: the device is installed on the central support and the recessing tool rotates, helping chip management and making easier the machining of tough materials, also available with internal refrigeration.
