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.

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 have been 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 two-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 parting off to centre in good conditions in most materials and light intermittent applications, such as parting hexagonal bars.

-CR geometry

Productive parting off geometry for a big variety of workpiece materials. Use when a strong edge line is needed, for example for interrupted cuts.

-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 giving good surfaces.

-GL geometry

Parting and grooving geometry for long chipping materials using low to medium feed. Features the most agressive chip breaker in the CoroCut® concept.

-TF geometry

The most universal geometry in CoroCut®, possible to use in all application areas. Designed for low feed and good chip control. Good surface finish due 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 depth of cuts. The perfect choice for finishing of 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.

Grade positioning

Main grades

GC1225: First choice grade for CoroCut. For all parting, grooving and turning operations in good conditions. Works well on low carbon and other smearing materials. Medium cutting speeds.

GC1135: For operations demanding toughness, such as parting off to center and interrupted cuts. Same grade as 2135, renamed to follow CoroCut QD/QF/QI. Low to medium cutting speeds.

GC1145: For operations demanding extreme toughness, such as interrupted cuts and parting off to center in stainless steel. Low cutting speeds.

GC4425: Excellent combination of high wear resistance and good edge security. To be used in grooving, turning and parting off operations in stable conditions. Medium to high cutting speeds.

CT5015: A titanium-based grade with excellent resistance to oxidation and smearing. For high quality surface finishes when grooving low-alloy steels in fairly good conditions. Moderate cutting speeds and feeds.

GC3115: A highly wear-resistant grade for grooving and turning applications under stable conditions. Also effective in hard steels. High cutting speeds.

H13A: Good wear resistance and toughness combined with edge sharpness. To be used on non-ferrous and titanium materials.

S205: A wear resistant CVD-coated grade for high-speed finishing in the cutting speed range between legacy carbide grades and CBN grades.

GC1205: Grade for machining aged nickel-based HRSA materials. Offers good adhesion and flank wear resistance. The hard substrate and PVD coating allow for a significant increase in cutting speed and tool life.
