Get into the groove

Seco’s CP200 has long been an excellent grade for parting-off and grooving operations involving challenging materials. To further increase the versatility of this proven PVD product, the company has now made it available for MDT (multi-directional turning) applications.

While primarily intended for superalloys, including Inconel, Hastelloy and Waspaloy, as well as highstrength steels, the new CP200 for MDT is also highly productive when cutting cast iron with low hardness and martensitic stainless steels.

The latest inserts feature an optimised micrograin and sharp, periphery-ground cutting edge that allows them to excel in high-speed operations and maintain a high resistance to plastic deformation.

In general, the CP200 grade complements Seco’s uncoated 883 grade, and can be paired with the company’s Jetstream Tooling to further enhance chip control, productivity, surface finish and overall component quality.

Jetstream Tooling delivers high-pressure coolant directly to the cutting edge to remove heat from the cutting zone and facilitate higher cutting speeds.

The CP200 range includes three chipbreaker options: FT for fine turning and deep grooving; MP for medium turning, profiling and grooving with good accessibility; and RP for fine and medium turning, profiling and grooving. Furthermore, the grade is offered in single and double-ended inserts and in cutting edge widths from 3 mm to 10 mm (0.125" to 0.25").
