CPMW 080204 T5115 — ISO turning insert, CVD-coated carbide (Tungaloy)

A CPMW 080204 T5115 indexable turning insert for external and internal turning, offering a universal grade optimised for cast iron with a stable cutting edge and standard ISO compatibility

• CVD-coated universal grade T5115
• ISO CPMW080204 rhombic insert
• Corner radius 0.4 mm for consistent profile
• Cylindrical hole with 40°–60° countersink

High-performance cutting for cast iron with proven coating technology

The CPMW insert combines a CVD coating with a wear-resistant cemented carbide substrate to deliver a balance of edge stability and abrasion resistance tailored for cast-iron machining. The T5115 grade is formulated as a universal solution for grey and nodular cast irons, which means fewer insert changes and longer periods of productive cutting. The chemically vapour deposited coating enhances resistance to built-up edge and thermal stress, helping to maintain dimensional stability over serial runs.

Precise geometry and ISO conformity for predictable toolholding

Designed as an ISO-standard rhombic insert, the plate features a defined 80° shape angle and a 11° clearance angle, ensuring reliable seating in compatible holders. The rhombic shape and the corner radius 0.4 mm produce repeatable part contours and controlled engagement at the cut. The insert is supplied with a cylindrical hole plus a one-sided countersink (40°–60°) to match common clamping systems; however, final compatibility depends on holder form, tolerance class, fastening and thickness—check the holder specification before assembly.

Durable edge life for steady productivity

The combination of a robust carbide substrate and the CVD surface treatment delivers steady wear behaviour and resistance to thermal softening under moderate to high cutting speeds. This results in longer tool life, fewer interruptions for index changes and a predictable process window for serial production. The absence of a dedicated chipbreaker in this variant makes it suitable for operations where chip control is managed by cutting conditions, tool overhang or external chip-guiding devices, rather than relying on an aggressive built-in breaker.

Application guidance and selection tips for reliable results

As part of an ISO insert system, the CPMW 080204 is best used with a matching external holder or boring bar, an appropriate clamping pad or clamping kit, and the correct screw set. For external and internal turning of cast-iron components, start with conservative speeds and feeds to verify surface finish and thermal behaviour, then adjust for higher productivity. When machining different cast-iron grades or varying machine rigidity, consider alternative grades or chipbreaker geometries for optimal control; our technical advisers can help with grade selection and cutting parameter recommendations.

FAQ

Which materials is this insert suitable for? The T5115 grade is a universal, CVD-coated carbide optimised for machining cast iron; it is primarily specified for grey and nodular cast irons.

How is the insert secured in the holder? The insert uses a cylindrical hole with a one-sided countersink (40°–60°) and is clamped by the matching holder, pad and screw; check holder tolerance and fastening type for proper seating with the CPMW 080204 insert.

What are the key geometry values to consider for setup? Refer to the 80° shape angle, 11° clearance and 0.4 mm corner radius when selecting feed and depth values for predictable form and surface finish.

Is there a chipbreaker on this variant? This variant is supplied without a chipbreaker, so chip control is achieved via cutting conditions, tool orientation or external chip guidance rather than an integrated breaker geometry.

Can the insert be used for internal turning? Yes, the CPMW 080204 insert is suitable for both external and internal turning operations when paired with an appropriate boring bar or internal holder.
