Designed for roughing and semi-finishing of steel and cast iron in turning applications, Seco’s new negative-styled M6 chipbreaker inserts provide excellent productivity and versatility. Available in a variety of double-sided geometries, the M6 includes a wide positive protection chamfer, a positive rake and a wide groove to achieve high edge strength, low energy consumption and efficient chip evacuation. The chipbreaker geometry provides high resistance against chipping, crater wear and flank wear, which results in optimal tool life.

To further boost productivity, the range includes double-sided, high-feed inserts. The M6 wiper design allows for higher feed rates, while delivering secure chip control, low cutting forces and reliable wear behaviour. Such benefits bring forth superior part quality and smooth surface finishes, eliminating the need for finishing operations in some applications.

The M6 is available in several Duratomic® grades, including TP0500, TP1500, TP2500 and TP3500 for steel operations and TK2001, which is primarily for nodular cast iron. The M6 in grades TP2500 and TP3500 provides an easy cutting action that offers strong performance in ferritic and martensitic stainless steels. Typical industry segments where M6 can provide a substantial benefit include general machining, automotive, bearings and pumps.

erfect for small-part manufacturers, the Seco X4 multi-edge system meets the industry’s demand for grooving and parting-off tools with narrow cutting edges. Most recently, the company added smaller shanks to the short-reach system so that it can accommodate an even broader range of machining applications such as Swiss parts.

The X4 consists of indexable tangential inserts with three-dimensional chipbreakers and a highly stable clamp design. These strong, dependable system components achieve high accuracy, repeatability, productivity and surface quality in external grooving and parting-off operations involving small parts, slim bars and tubes made from a wide variety of common materials.

The system’s MC chipbreaker inserts cover cutting-edge widths from 0.5 mm to 3 mm and cutting depths between 2.6 mm and 6.5 mm. Maximum bar diameter for cut off varies from 5.2 mm to 13 mm in diameter, depending on insert width. Insert profiles are available in neutral and angled right-handed and left-handed versions.

Flat profiles, designated R and FG, with positive rakes are also available. Featuring a round profile, the R-style inserts for grooving and profiling have cutting edges with widths that range from 1 mm to 3 mm.The FG-style inserts cover groove widths from 1.15 mm and 2.65 mm and can machine lock-ring grooves to DIN471, DIN472, SMS1581 and SMS1582 standards.

In terms of insert grades, the X4 system uses CP500 for increased wear resistance in challenging cutting scenarios and CP600 for a combination of toughness and wear resistance in general machining applications.

An upper clamp rigidly holds the inserts, and it is possible to fasten and release the clamping screw from the top or bottom. X4 toolholders come in a wide variety of shank sizes, including 1212, 1616, 2020 and 2525 as well as Seco-Capto C4, C5 and C6. The newest 1212 and 1616 shanks with a compact toolholder head design bring the reliability and value of the X4 system to small sliding head machines, where there is a need for small holders with cutting edges of narrow widths. Particularly advantageous is the fact that one toolholder works for all X4 insert types, allowing for a reduction in tooling inventory.

All X4 toolholders, except for the toolholder head design for the 1212 shanks, incorporate Seco’s Jetstream Tooling® Duo technology that has coolant outlets from both the clamp and underneath the insert to further enhance productivity, lengthen tool life and improve chip control. By delivering coolant from two outlets to optimum points in the cutting and heat zones, Jetstream Tooling Duo contributes to efficient cooling, ideal chip formation and high part quality.

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 high-strength 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”).
