CNMG120404 T505 — ISO rhombic indexable turning insert, CVD-coated carbide by Tungaloy

CNMG120404 T505 is a rhombic indexable turning insert optimised for efficient external and internal turning, especially for cast-iron applications, delivering repeatable edge life and stable chip control.

• ISO rhombic insert CNMG120404 form
• CVD-coated carbide grade T505 for cast iron
• Double-sided chipbreaker, cylindrical hole
• 0.4 mm corner radius, 80° cutting angle

Efficient cast-iron turning with reproducible edge life

The CVD coating and the T505 grade carbide combine to create a wear-resistant cutting edge that is suited to economic machining of cast iron. The coating reduces flank and crater wear under typical interrupted and continuous cuts, which results in longer in-cycle life and fewer insert changes. Thanks to the double-sided chipbreaker, chips are segmented reliably, reducing the risk of chip-related surface damage and promoting safer, unattended operation.

Secure geometry and reliable clamping for process stability

The rhombic CNMG form with a cylindrical hole and standard ISO datum ensures consistent seating and repeatable positioning in ISO-compatible holders. The 80° cutting angle and 0.4 mm corner radius balance strength and edge sharpness, enabling stable cutting forces and predictable tool deflection. This geometry supports standard clamping systems and simplifies tool inventory by using well-known ISO specifications for holders, clamp sets and replacement screws.

Productivity gains from focused tool design

Designed for production contexts, the combination of CVD-coated surface and precise grade selection delivers a favourable cost-per-part ratio for turning operations. The plate thickness and form contribute to secure mounting and higher allowable feed rates under appropriate rigidity; in practice this means faster cycle times without sacrificing surface integrity. For workshops seeking consistent throughput, this insert supports efficient changeover and repeatable results across series production.

Compatibility, system setup and application advice

The insert is supplied in the ISO indexable turning insert system and pairs with matching external holders or boring bars; compatibility depends on form, clearance angle, tolerance class, attachment and plate dimensions. As a turning solution, selection of the correct chipbreaker and grade for workpiece stability and cutting conditions is essential — the T505 grade suits a broad range of cast-iron types and cutting strategies. For mixed-material shops, consider toolholder rigidity and cutting data adjustments when moving between cast iron and other materials.

FAQ

What materials is this insert designed for?
The CNMG120404 T505 insert is designed primarily for machining cast iron; the T505 CVD-coated carbide grade provides good wear resistance and chip control on these materials.

Which chip control solution is integrated on the insert?
This insert features a double-sided chipbreaker, which supports reliable chip segmentation and smoother evacuation in turning operations.

How does the insert mount to a holder?
Mounting depends on ISO-compatible seat form and the insert’s cylindrical hole; the rhombic form and standard tolerances ensure repeatable seating in ISO turning holders and boring bars.

What are the key geometry parameters to consider for machining setup?
Key parameters include the 80° cutting angle, 0.4 mm corner radius and 4.76 mm plate thickness; these influence edge strength, surface finish and allowable feed rates.

Is this insert suitable for interrupted cuts?
Yes — the grade and geometry of the insert are selected for stable performance in both continuous and interrupted turning, provided suitable holder rigidity and cutting data.
