Walter has introduced the Walter Cut G2042 series of grooving tools, featuring reinforced blades and a dual internal coolant delivery system. In grooving and parting off operations, cutting edges are exposed to high mechanical and thermal stresses. Effective cooling and lubrication is imperative.

The G2042 system precisely delivers coolant to the flank and to the chipbreaker of the insert.


The result: A constant optimum operating temperature with the coolant stream targeting the center of the chip formation. This leads to better chip control, which in turn produces improved surface finishes and flatness and better tool life.

The Walter Cut G2042 parting blades with precision cooling are available in blade sizes of 1.02 in. and 1.26 in. (26-32 mm0. Inserts for the G2042 are available in widths of 2-4 mm. Prime target applications include turret turning centers with bar feeders parting off to center and performing depths of cut greater than 0.315 in. (8 mm), particularly on difficult to machine materials, especially high temperature alloy materials.
