CoroCut® QD

High-precision coolant

​Over- and under-coolant system cools the cutting zone for better chip control, extended tool life and higher cutting data. Provides easy coolant connection with plug-and-play adapters.

Grades and geometries for parting off

​Geometries designed for good chip formation, high stability and coolant access in combination with grades that provide excellent edge-line security in all materials make for inserts that excel in every parting-off operation.

Y-axis parting

​CoroCut® QD, for Y-axis parting, is designed with the insert pocket rotated 90 degrees, providing more than six times higher blade stiffness in turning centers and multi-task machines with Y-axis.

View More Features
  • Stable, user-friendly clamping with a railed insert seat for a precise insert position and a quick-release key that eliminates the need for a torque wrench
  • Adjustable cutting depth and overhang with maintained coolant
  • Made of a strong material alloy with high fatigue resistance, the blades are optimized for reliable parting off and deep grooving. Reinforced parting blades are also available – perfect when working with long overhangs.
  • Flexible tool options – assortment includes parting blades, shanks and QS™ shanks for sliding head machines, as well as CoroTurn® SL blades for modular machining.

Y-axis parting: turning re-invented

Get to know Y-axis parting – a completely new way of parting off. While conventional parting off uses feed motion along the X-axis with the cutting force directed through the weakest section of the blade, CoroCut® QD for Y-axis parting is designed with the top face of the insert perpendicular to the blade. This gives a more beneficial direction of the cutting force, resulting in considerably higher stability and reduced vibration.

CoroCut® QD for Y-axis parting is the first choice for parting off in turning centers and multi-task machines with Y-axis. It can machine large diameters up to 180 mm (7 inch), and is particularly suitable for reaching between the main- and sub-chuck with long overhangs.

Behind the scenes of Y-axis parting

To truly advance parting off operations, it is not enough to develop a new tool—you need to develop the method for using it. Meet Staffan and Johan, the brains behind the new ingenious way of parting along the Y-axis, which challenges conventional machining.
