DCMT 11T308 T9215 indexable turning insert by Tungaloy — ISO rhombic, CVD‑coated carbide

A DCMT11T308 T9215 ISO‑standard turning insert designed for external and internal turning in medium steels, offering a balanced mix of wear resistance and fracture toughness.

• ISO rhombic insert, 55° cutting angle
• CVD‑coated carbide grade T9215
• 0.8 mm corner radius for stable cutting
• Cylindrical hole with single‑side countersink

High productivity for medium‑steel turning

The T9215 grade is a CVD‑coated carbide designed as a first choice for productive medium‑steel machining. The coating provides elevated wear resistance, while the substrate retains sufficient toughness to resist chipping under continuous to lightly interrupted cuts. As a result, the insert supports higher material removal rates and longer tool life compared with uncoated grades, translating into lower machining times and fewer index changes per shift.

ISO geometry and secure clamping for consistent results

The rhombic ISO shape with a 55° cutting angle and 7° relief ensures compatibility with standard DCMT holders; fit and repeatability depend on holder form, relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) that enables reliable clamping and reproducible seating on the pocket, reducing vibration and positional variance across repeat tool changes. The 3.97 mm plate thickness contributes to rigidity in the clamping system for stable cutting.

Controlled chip formation and surface quality

A 0.8 mm corner radius combined with a single‑sided chipbreaker balances edge strength and surface finish: the radius reinforces the cutting edge for robustness on heavier feeds, while the chipbreaker shapes chips for consistent evacuation in external and internal turning. The geometry supports a good surface finish without sacrificing durability, especially when machining medium steels under steady feed and speed regimes.

Practical benefits for production workflows

The insert’s ISO conformity simplifies inventory management and changeover; the DCMT form is widely supported by standard outer holders and boring bars, enabling quick replacement and minimal downtime. The combination of CVD coating and a tough carbide core reduces unscheduled stoppages, increases process security and helps maintain component tolerances over longer tool life, contributing to predictable production throughput.

FAQ

What workpiece materials suit this insert? The Tungaloy DCMT11T308 T9215 insert is optimised for medium steels; the T9215 grade combines wear resistance and toughness for continuous and lightly interrupted turning on steel alloys.

How is compatibility with a holder determined? Compatibility depends on holder form, relief angle, tolerance class, fastening method, insert size and thickness; the ISO rhombic form and the 55° cutting angle require a matching DCMT‑capable outer holder or boring bar.

What effect does the 0.8 mm corner radius have on machining? A 0.8 mm corner radius increases edge strength and improves tool life at higher feeds, while offering a balance between robustness and achievable surface finish compared with smaller radii.

Does the insert require a special clamping screw or seat? The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) for standard indexable insert clamping; proper seating and torque on the clamping screw ensure repeatable positioning.

Which chip control can be expected with this design? The single‑sided chipbreaker provides controlled chip formation for stable evacuation and consistent surface quality when machining medium steels under recommended cutting conditions.
