What's new?
Upgraded inserts offer cost-efficient machining
CoroCut® 2 inserts are produced with a unique, in-house developed patented technology, resulting in improved edge line quality for a superior tool life. Even the smaller inserts now feature the rail interface, which offers a more precise insert position and minimizes insert movement for improved stability. The wiper design on all parting geometries ensures an excellent surface finish. All new inserts are compatible with existing CoroCut 1-2 tool holders.
New and updated high-performance grades
The new first-choice grade GC1225 offers superior flank wear resistance and edge line toughness and is ideal for all parting, grooving and turning operations in good conditions. Grade GC4425 offers an excellent combination of high wear resistance and good edge security for grooving, turning and parting off operations in stable conditions. Our latest addition, grade GC1205, is developed for machining aged nickel-based HRSA materials and offers good adhesion and flank wear resistance.
Improved clamping design on precision coolant tools
CoroCut® 2 parting blades are upgraded with internal coolant and an improved clamping finger design, which ensures a higher clamping force and better lateral stability. Tool holders with precision coolant are updated with a screw clamp solution. Combined with the new rigid rail insert seat design, insert movement is reduced to a minimum without any loss of clamping force.
Application
- Parting off, external grooving, face grooving, internal grooving and profiling
- Roughing to finishing
CoroCut® 2 is a cost-efficient solution for cutting depths where double-edged inserts can be used. CoroCut® QD and CoroCut® QF are the best choices for larger depths of cut and CoroCut® QI is recommended for face and internal grooving in small diameters.

-CM geometry
First choice for optimal center parting off in most materials and light intermittent applications, for example parting hexagonal bars.
-CR geometry
Productive parting-off geometry for a wide variety of workpiece materials. Use when a strong edge line is needed, for example for interrupted cuts.
-CS geometry
First choice parting-off geometry for eliminating pips and burrs. Suitable for both bars and tubes, and a wide variety of workpiece materials, mainly ISO P and ISO M.
-GF geometry
Ground geometry used with low feed for precision grooving. Low cutting forces and good surface finish. Available in many cutting widths and grades.
-GM geometry
Universal grooving geometry for all materials with outstanding chip control. Reduces chip width to guarantee good surfaces.
-GL geometry
Parting and grooving geometry for long chipping materials using low to medium feed. Features the most aggressive chip breaker in the CoroCut® concept.
-TF geometry
The most universal geometry in CoroCut®, ideal for use in all application areas. Designed for low feed and good chip control. Good surface finish thanks to the wiper design.
-TM geometry
Geometry with strong edge and corners for general turning operations in all materials. A positive geometry eliminates the risk of built-up edge.
-RF geometry
Finishing geometry for profiling operations with low feeds and small depths of cut. The perfect choice for finishing HRSA components.
-RM geometry
Universal profiling geometry with a wide cutting data window. Excellent performance when used in non-linear profiling. Flashlight technology edge line quality allows for -RM in grade S205.
RO geometry
