DCMT 11T304 T505 Tungaloy indexable insert for turning — CVD-coated carbide, 55° rhombic

The DCMT 11T304 T505 is an ISO-standard turning indexable insert designed for efficient external and internal turning, particularly suited to cast-iron applications with stable chip control.

• ISO-standard rhombic 55° geometry
• CVD-coated carbide, grade T505
• Optimised for cast iron machining
• 0.4 mm nose radius for stable finish

Increased productivity through a specialised grade and coating

The combination of a CVD-coated carbide substrate and the T505 grade delivers a balance of wear resistance and cutting economy for series production. This composition reduces flank wear under normal cutting speeds while allowing longer tool life compared with uncoated grades. The formulation is particularly suited to the removal of cast iron, where controlled abrasion resistance and consistent edge stability result in fewer insert changes and reduced downtime. As a result, shops gain measurable improvements in throughput and process reliability.

Geometry engineered for repeatable surface quality

The rhombic form with 55° geometry and a 0.4 mm nose radius provides a compromise between strength and finish capability: the sharper effective cutting angle eases chip evacuation, while the small radius supports acceptable surface finish without compromising edge robustness. The insert’s ISO-standard footprint ensures consistent seating and clamping, and the 3.97 mm plate thickness contributes to rigidity during heavier cuts. These geometric choices reduce vibration and deliver repeatable component tolerances, supporting tighter process windows on turning tasks.

Compatibility that simplifies tool assembly and inventory

Designed as part of an ISO insert system, the indexable plate fits a wide range of compatible external holders and boring bars; compatibility is governed by form, clearance angle, tolerance class, fixing method, size and thickness. The presence of a cylindrical hole plus single-sided countersink (40°–60°) enables secure clamping and quick replacement. Organising tooling around standardised inserts reduces the number of unique toolholders required, simplifies stock management and shortens set-up time at the machine — a practical benefit for mixed-production workshops.

Chip control and application guidance for reliable turning

A one-sided chipbreaker geometry is integrated to promote stable chip formation across a spectrum of cutting conditions. For interrupted cuts or less rigid setups, select a more robust holder and moderate cutting parameters; for continuous light cuts, the insert’s chip control supports higher surface quality and longer intervals between indexings. While the insert is optimised for cast iron, the combination of grade and chipbreaker makes it applicable where economic machining and predictable chip behaviour are required, helping to maintain cycle time consistency and reduce scrap.

FAQ

What materials is this insert intended for?
The DCMT 11T304 T505 insert is optimised for machining cast iron; its T505 grade and CVD-coated carbide construction were selected to provide economical performance on cast-iron workpieces.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; the DCMT11T304 fits standard ISO rhombic holders designed for 55° inserts and secures via the cylindrical hole plus single-sided countersink.

How does the 0.4 mm nose radius affect surface finish and tool life?
A 0.4 mm nose radius offers a compromise between strength and finish: it supports improved surface quality on finishing cuts while retaining enough edge support for stable tool life in general turning operations.

Is this insert suitable for interrupted cuts or unstable setups?
The insert’s geometry and one-sided chipbreaker provide decent chip control, but for heavily interrupted cuts or less rigid setups, pairing with a robust holder and conservative cutting data is recommended to maintain edge life.
