DCMT11T304 T515 ISO rhombic turning insert by Tungaloy — CVD-coated carbide, 55°

The DCMT11T304 T515 is an ISO-standard rhombic turning insert intended for economical and stable machining of cast iron in both external and internal turning applications.

• ISO 55° rhombic geometry for versatile turning
• CVD-coated carbide grade T515 for cast iron
• 0.4 mm corner radius for accurate profile
• Cylindrical hole with single-side countersink

Faster cycle times through optimised chip control and grade selection

The CVD-coated T515 carbide delivers a balance between wear resistance and cost-effectiveness, making the insert particularly suited for industrial cast-iron applications where productivity matters. The coating supports controlled chip formation, which reduces the risk of built-up edge and helps maintain consistent cutting forces during long runs. For interrupted cuts or variable stability conditions, choosing the appropriate chipbreaker and setup improves component quality and shortens cycle times. This technical approach to chip management yields measurable improvements in throughput and process stability.

Consistent tool life and predictable surface quality for demanding production

A carbide substrate combined with the CVD layer enhances flank and crater wear resistance, contributing to predictable edge life over repeated operations. The 7° relief angle and robust cutting geometry maintain a stable cutting edge under moderate to heavy feed rates, which in turn supports a consistent surface finish on cast-iron parts. Reduced maintenance and fewer insert changes translate into less unplanned downtime and improved overall equipment effectiveness, supporting longer production runs with steady quality.

Simple integration into ISO tool systems and precise seating for accuracy

Being an ISO-standard insert, compatibility with holders is determined by form, clearance, tolerance class, fastening method, size and thickness. The rhombic 55° shape offers flexibility for both external and internal turning, while the 0.4 mm corner radius balances profile accuracy with edge strength. The insert measures 11 mm across the size designation, with a plate thickness of 3.97 mm and a cylindrical hole with a single-side countersink (40°–60°) for secure clamping. These dimensional details ensure predictable seating and repeatability in indexable tool systems, easing setup and reducing alignment effort.

FAQ

What materials is this insert suitable for? The DCMT11T304 T515 insert by Tungaloy is recommended primarily for machining cast iron; the T515 CVD-coated carbide is optimised for economic and stable cutting of grey and nodular cast irons.

Can the insert be used for interrupted cuts? Yes, the coated carbide grade and robust geometry of this turning insert support interrupted cutting when the correct chipbreaker and stable setup are selected.

How does the 0.4 mm corner radius affect the process? A 0.4 mm corner radius increases edge strength and helps maintain profile accuracy; it is a compromise between finer surface finish and increased resistance to edge chipping.

Which holders are compatible with this ISO insert? Compatibility is determined by insert form, 7° relief, tolerance class, fastening and the insert dimensions (11 size, 3.97 mm thickness); use a matching ISO rhombic holder designed for DCMT inserts.

What is the mounting hole type and why does it matter? The insert has a cylindrical hole with a single-side countersink (40°–60°), which ensures secure clamping and correct seating in compatible insert seats, improving repeatability and stability during turning.
