DCMT 11T302 GT9530 indexable insert for turning (Tungaloy)

DCMT11T302 GT9530 is an ISO-designation indexable insert for external and internal turning applications, offering a cermet grade tailored to finishing and light universal machining of steel.

• DCMT 11T302 geometry for ISO turning
• Coated cermet GT9530 for long tool life
• 7° clearance angle for stable finishing
• Cylindrical hole with countersink 40°–60°

Improved surface finish and extended tool life for finishing

The GT9530 grade is a coated cermet developed for wear resistance in finishing and light universal turning of steel under stable machining conditions. Its composition and coating reduce notch wear and promote a consistent cutting edge, which translates into a better surface finish and longer intervals between insert changes. For operations where a fine part finish and predictable tool life are priorities, this grade offers measurable advantages in uptime and component quality.

ISO compatibility and secure clamping for repeatable results

The insert conforms to ISO geometry, designated as DCMT11T302, which aids compatibility with standard external holders and boring bars. Critical geometric data — size 11, thickness 3.97 mm, corner radius 0.2 mm and a 7° clearance angle — determine holder selection and clamping fit. Ensuring the correct form, clearance, tolerance class, fastening method, size and thickness maintains repeatable seating and stable cutting conditions, reducing vibration and the risk of machining errors.

Practical application guidance for turning tasks

Designed primarily for external and internal turning, the insert is most effective when paired with an appropriate single-sided chipbreaker and when machining parameters are matched to the workpiece material and machine rigidity. The one-sided chipbreaker supports controlled chip formation in finishing passes, while the coated cermet composition favours consistent edge condition during serial work. For light universal cutting or when a high-quality surface is required, this insert provides a reliable balance between finish and life.

Selection and handling recommendations to optimise performance

Select the chipbreaker and grade according to the workpiece material and the intended cut. The cylindrical hole with a single-sided countersink (40°–60°) secures the insert in many standard clamping systems; confirm compatibility with the clamping screw and seat. Store inserts in their original packaging to protect edges, and replace inserts before edge degradation affects part quality. For specific mounting or process advice, consult technical documentation or seek application support to align holder geometry, cutting data and machine rigidity.

FAQ

Which machining operations suit this insert best? This insert is intended for external and internal turning; the GT9530 grade focuses on finishing to light universal operations where a good surface finish and extended tool life are required.

What materials can be machined with this grade? The GT9530 coated cermet is optimised for machining steel in stable conditions, providing improved wear resistance for finishing applications.

How does the GT9530 grade affect process stability? The coated cermet composition of GT9530 helps maintain a stable cutting edge, reducing wear-related variation and supporting consistent surface quality over longer production runs.

Which dimensions are critical for holder compatibility? Confirm holder compatibility with the insert’s form, clearance angle, tolerance class, fastening method, size (11) and thickness (3.97 mm); these factors determine secure seating and repeatable clamping.

Is this insert suitable for heavy roughing operations? As a finishing to light universal grade, this insert is not optimised for heavy roughing; choose a more robust grade and chipbreaker for high material removal rates.
