DCMT11T308 T515 ISO rhombic turning insert for turning — Tungaloy

The DCMT11T308 T515 is an ISO-format rhombic insert tailored for economical external and internal turning of cast iron, offering a balanced mix of wear resistance and chip control.

• CVD-coated carbide grade T515
• Economical cast iron machining
• Rhombic 55° cutting geometry
• Single-sided chipbreaker with drilled hole

Consistent chip control for productive cast-iron turning

The CVD-coated carbide grade T515 provides a wear-resistant surface that helps maintain cutting-edge integrity during sustained production runs. Combined with the single-sided chipbreaker, this geometry promotes stable chip formation, which reduces interruptions and the need for manual chip clearing. For workshops seeking to increase throughput while keeping tooling costs in check, the insert’s coating and substrate chemistry deliver economical machining without sacrificing process stability. The result is fewer tool changes and a more predictable tool-life profile.

Proven geometry and secure clamping for predictable results

As an ISO rhombic insert with a 55° approach, the geometry balances cutting forces and surface finish expectations in typical turning setups. The specified clearance angle of 7° and corner radius of 0.8 mm contribute to a compromise between edge strength and achievable surface quality. The insert is supplied with a cylindrical hole and one-sided countersink (40°–60°) for secure fastening; compatibility with a holder depends on form, clearance angle, tolerance class, fastening style, size and thickness. The 3.97 mm plate thickness and size 11 designation ensure compatibility with standard external holders designed for ISO indexes.

Application guidance for reliable process integration

Designed primarily for cast iron workpieces, the grade suits both continuous and intermittent cuts when the correct chipbreaker and clamping stability are chosen. Select the chipbreaker and cutting parameters according to component rigidity and interruption frequency: a stable setup enables higher feed rates and more aggressive material removal, while less rigid conditions benefit from reduced depths of cut. The insert’s characteristics support production-focused strategies where repeatability and throughput are priorities, providing a practical path to improved component output and lower cycle-time variability.

Simple system assembly and operational benefits

The insert forms part of a straightforward system: an ISO turning plate, compatible external holder or boring bar, a shim/clamping set and replacement screws. Proper assembly and torqueing of the clamping components are essential to exploit the T515 grade’s potential and avoid premature edge failure. For machine shops standardising on reliable, readily available inserts, the combination of established ISO geometry and a coated carbide substrate simplifies inventory management and contributes to consistent process results across batches.

FAQ

Which materials is this insert suitable for?
The DCMT11T308 T515 insert is optimised for the economical machining of cast iron; the CVD-coated carbide substrate ensures wear resistance appropriate for grey and nodular cast iron machining.

How is holder compatibility determined for this type of insert?
Compatibility depends on the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic 55° geometry and the specified hole/countersink require a matching ISO-style holder.

What advantage does the T515 grade offer?
Grade T515 is a CVD-coated carbide developed for economic cast-iron operations, providing a good balance between cutting-edge wear resistance and cost-efficiency in series production.

Can this insert be used for interrupted cuts?
Yes; interrupted cuts are possible but it is important to select the appropriate chipbreaker and ensure sufficient clamping stability to protect the cutting edge from shock loads.

Why does corner radius matter and what does 0.8 mm deliver?
A 0.8 mm corner radius increases edge robustness compared with smaller radii, improving resistance to edge chipping while offering a reasonable surface finish for general turning operations.
