DCMT11T312 T9215 Tungaloy insert — ISO rhomboid turning insert, CVD-coated carbide, 1.2 mm radius

The DCMT11T312 T9215 Tungaloy insert is an ISO rhomboid turning insert engineered for general turning tasks on medium steel, combining a CVD-coated carbide grade with a robust chipbreaking geometry for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• 1.2 mm corner radius for strength
• ISO rhombic plate, size 11, 3.97 mm thick
• Cylindrical hole with 40°–60° single-sided countersink

Achieve higher uptime through durable cutting performance

The CVD-coated carbide grade T9215 provides a balance of wear resistance and fracture toughness, enabling longer tool life under stable machining conditions. The coating promotes consistent edge behaviour at elevated cutting speeds, which translates into fewer insert changes and less downtime. With a 1.2 mm corner radius, the insert achieves improved edge strength that reduces the risk of premature chipping during medium-depth turning operations. This combination allows workshops to sustain production rates while controlling tool-related variables and overall process costs.

Predictable clamping and simple integration in ISO systems

Designed to the ISO series for turning, the insert’s rhombic form and defined parameters ensure compatibility when the cutterholder is matched by form, clearance angle and size. The 7° clearance angle, 11 size and 3.97 mm thickness are measurable interface points that determine fit; the cylindrical hole with a single-sided 40°–60° countersink secures the insert reliably under axial and radial loads. Specifying holders that accept ISO rhombic inserts with matching tolerance classes and fastening methods delivers repeatable clamping and consistent cutting geometry, which benefits process control and surface finish predictability.

Better chip control and application guidance for turning

The insert’s one-sided chipbreaker is tuned for medium-steel applications, producing controllable chips in continuous to light interrupted cuts and helping to protect both the tool edge and the workpiece finish. For external turning and internal profiling, choose a chipbreaker and grade that suit workpiece rigidity and the intended depth of cut; the CVD-coated substrate performs well when stability and steady material removal are priorities. Where finer finishes are required, reducing feed or selecting a smaller corner radius will improve surface quality without sacrificing reliability.

FAQ

What materials is this insert suitable for? The DCMT11T312 T9215 Tungaloy insert is optimised for medium steel machining and performs best in continuous to light interrupted cuts where the T9215 grade’s wear resistance and toughness are valuable.

How can compatibility with an existing holder be ensured? Check that the holder accepts ISO rhombic inserts of size 11, 3.97 mm thickness and the 11T312 geometry; confirm the form, 7° clearance angle, tolerance class, fastening method and hole/countersink arrangement before fitting the insert.

What benefits does the T9215 CVD coating provide? The CVD-coated carbide T9215 improves surface hardness and thermal stability at the cutting edge, resulting in enhanced wear resistance and reliable edge life under elevated speeds, which supports higher productivity and consistent component quality.

Is the insert suitable for internal turning operations? Yes, the geometry and chip control of this indexable insert are appropriate for internal turning as well as external profiling, provided the holder and tool overhang allow for stable cutting conditions.

When should the 1.2 mm corner radius be preferred or avoided? The 1.2 mm radius offers a robust edge for general turning and semi-roughing; for very fine finishing operations or when tight dimensional tolerances demand minimal tool engagement, a smaller corner radius is preferable to reduce cutting forces and improve surface finish.
