CPMT09T304 09T304 T9215 indexable turning insert — Tungaloy

The CPMT09T304 T9215 insert for ISO-standard turning, optimised for medium-steel external and internal machining.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• 0.4 mm corner radius
• Central hole with 40°–60° countersink

Consistent productivity for medium-steel turning

The insert combines a CVD-coated carbide matrix with the T9215 grade to deliver high wear resistance while retaining fracture toughness, which supports sustained productivity in continuous and lightly interrupted operations. Chemical vapour deposition (CVD) forms a hard, adherent coating layer that reduces flank wear and extends tool life under steady cutting conditions. This balance of hardness and toughness reduces rework cycles and contributes to predictable tool-change intervals in serial production.

Precision clamping and ISO conformity for repeatable results

Designed as an ISO-standard rhombic insert in 09 size with an 80° included angle and 11° clearance angle, compatibility with a toolholder is determined by shape, clearance, tolerance class, fastening, size and thickness. The geometry and a 3.97 mm thickness ensure stable seating and repeatable location in compatible external holders or boring bars. The insert forms part of a system comprising the indexable insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws, enabling straightforward installation and accurate repeatability across batches.

Application scope and secure mounting for reliable machining

The rhombic shape with a central hole (cylindrical with a single-side countersink at 40°–60°) and a one-sided chipbreaker make this insert suitable for both external and internal turning where medium-steel materials are predominant. The 0.4 mm corner radius provides a compromise between edge strength and surface finish, supporting moderate depths of cut while limiting edge chipping. Selection of chipbreaker and grade should be matched to workpiece material, machining type and machine-tool rigidity to exploit the insert’s strengths in stability and chip control.

FAQ

What materials is this insert intended for?
The CPMT09T304 T9215 insert is recommended primarily for medium steel machining and combines the Tungaloy T9215 grade with a CVD coating to handle such materials effectively.

Which toolholders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; the CPMT09T304 is an ISO rhombic 09 insert designed to fit standard ISO-compatible holders for turning.

How does the T9215 coating improve performance?
The CVD-coated T9215 surface provides enhanced wear resistance and maintains edge integrity, allowing productive turning cycles with improved tool life and consistent performance.

Is this insert suitable for interrupted cuts?
Yes, the insert is suitable for continuous to lightly interrupted cuts; its carbide grade and geometry balance wear resistance with fracture toughness to withstand mild interruptions.

What mounting features ensure secure clamping?
The insert features a central hole with a cylindrical bore and a single-side countersink (40°–60°), designed for secure, repeatable fastening in clamping systems.
