Energy and resource efficiency

  • Versatile tools with longer tool life enable reduced tool consumption
  • The improved security allows faster machining and increases overall efficiency, which translates to greater energy savings.*

*Based on tests in customer environment. In one case, CoroCut® 2 reduced power consumption by 38% and lowered CO2 emissions by 49% per year.

Cutting-edge insert technology

Engineered with our patented Flashlight technology and wear-resistant grades, CoroCut® 2 inserts deliver exceptional edge-line quality and long-lasting performance. For added stability in smaller insert seats, each insert features a rigid rail interface that locks into place with a reliable hold. Selected parting geometries also include a wiper design, ensuring excellent surface finishes.

The extensive range includes geometries and grades for every need, from ensuring chip control and minimizing tool wear to mastering tight tolerances in hard-to-machine materials.

-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.

-CS geometry

First choice parting-off geometry for eliminating pip and burrs. Suitable for both bars and tubes, and a wide variety of workpiece materials, mainly ISO P and ISO M.

-CO geometry

Ground parting-off geometry with a sharp edge, optimized for low feeds. Delivers low cutting forces and ensures tight tolerances in work-hardening materials.

-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.

-RO geometry

Ground, high-precision profiling geometry optimized for ISO M and ISO S, where a positive and sharp geometry is needed for high surface quality and tool life.

GC1145: For operations demanding extreme toughness such as interrupted cuts and parting off to centre on 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 under 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-alloyed steels under 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.

How to use

Recommendations

  • Start with first choice recommended cutting data
  • All cutting data recommendations are given without precision coolant
  • Increase speed by 30-50% when applying precision coolant
  • In parting off and external grooving CoroCut® 2 is a cost-efficient solution for cutting depths where 2-edged inserts can be used.

If CoroCut® 2 doesn’t suit your needs, see Parting and grooving tools page for more tool recommendations.

Insert recommendations

Insert seat sizes

  • The inserts are available in different insert seat sizes with different corner radii. All CoroCut® 2 inserts are fully compatible with existing CoroCut® 1-2 tool holders. However, to gain the benefit of a more precise insert position and minimized insert movement, a conversion to the new tool holders with the rail design is necessary for tip seat E-F-G.
  • The insert seat sizes must correspond with the holder seat size

Insert seat sizes

  • D with V-shape:
    • Insert widths: 1.5 mm (0.059 inch)
    • Cutting depth: 8–17 mm (0.315–0.669)
  • E-L with stable rail design:
    • Insert widths: 2–8 mm (0.079–0.315 inch)
    • Cutting depth: 8–32 (0.315–1.30 inch)

Undercutting with CoroCut® 2

CoroCut® 2 with two-edged inserts offers great chip control in undercutting operations with small clearance depths at low feeds.

  • -RM is an all-round geometry for profiling in all materials
  • Use the -RO geometry for operations in stainless steel, HRSA and other sticky materials

Circlip grooving

For low cutting forces and good surface quality, use CoroCut® 2 with -GF geometry.
