DCMT 070204 T9215 Turning insert — Tungaloy, CVD-coated carbide, 7° clearance

DCMT070204 T9215 is an ISO-format indexable turning insert for external and internal turning applications, optimised for medium-steel machining.

• CVD-coated carbide for long tool life
• Single-sided chipbreaker for controlled chips
• Rhombic 07 form with 55° cutting angle
• 0.4 mm corner radius for fine surface quality

Reliable wear resistance for productive turning

The CVD-coated carbide grade T9215 combines high wear resistance with mechanical robustness, making it a suited choice for medium-steel operations where continuous to slightly interrupted cuts are common. The coating reduces flank wear and helps maintain a stable cutting edge over longer runtimes, which in turn supports more consistent cycle times and fewer tool changes. As an ISO-compatible insert, it contributes to predictable process economics and easier stocking within a standardised tooling system.

Precise geometry for secure clamping and consistent finishes

The rhombic insert geometry with a nominal 55° cutting angle and a 7° clearance ensures secure seating in compatible holders and predictable cutting forces. The 0.4 mm corner radius supports improved surface quality on finishing passes while the single-sided chipbreaker promotes controlled chip formation under a variety of cutting conditions. A cylindrical hole with a one-sided countersink (40°–60°) improves repeatable positioning and clamping reliability, reducing the risk of insert movement even at higher feed rates.

System compatibility that reduces downtime

ISO-format indexable inserts require matching holders and clamping kits; compatibility is determined by shape, clearance angle, tolerance class, fastening method, size and thickness. The insert is part of a practical system comprising the indexable plate, an appropriate external holder or boring bar, a locating shim or clamp set, and replacement screws. This system approach minimises set-up time and supports swift replacement routines on the shop floor, improving overall equipment effectiveness and helping to maintain steady production output.

Application guidance and machining tips

Designed primarily for turning of medium steels, the insert performs best when the chipbreaker and grade are matched to the workpiece material, machining strategy and part stability. The plate thickness of 2.38 mm and the 07 size make this insert suitable for a range of toolholders aimed at small- to medium-diameter turning. For optimal results, pair the insert with a holder that matches the 55° geometry and verify clamping torque and seating cleanliness before cutting. Where slightly interrupted cuts occur, T9215’s blend of abrasion resistance and toughness helps avoid premature edge failure.

FAQ

What materials is this insert best suited for?
The DCMT070204 T9215 indexable insert is optimised for medium steels; the CVD-coated carbide grade T9215 provides a balance of wear resistance and toughness for productive steel turning.

Can the insert be used for interrupted cuts?
Yes, the T9215 grade and the insert’s mechanical robustness allow for continuous to slightly interrupted cuts; however, severe interruptions require application-specific verification.

Which holder geometry is required for this insert?
Holders must match the rhombic 07 form, 55° cutting angle and 7° clearance; compatibility depends on form, tolerance class, fastening and thickness so use a matched ISO-compatible holder.

How does the chipbreaker affect performance?
The single-sided chipbreaker promotes controlled chip flow for stable cutting and improved surface quality when machining medium steel with appropriate feeds and speeds.
