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.
HRSA profiling without compromise
CoroCut® 2 offers optimized inserts for demanding HRSA materials, including grades GC1205, S205 and H13A along with -RF, -RM and -RO profiling geometries that ensure controlled chip flow and tight tolerances.
Applied with our knowledge and support, CoroCut® 2 secures reliable, efficient parting and grooving and a stable process you can trust at every step.

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.
