VCMT 160408 T505 — VCMT ISO rhombic turning insert for turning by Tungaloy, CVD-coated carbide, 35°

A VCMT160408-CM T505 is an ISO rhombic turning insert designed for efficient external and internal turning, optimised for cast-iron machining with a stable chipformer and ISO-compatible mounting.

• CVD-coated carbide grade T505
• Optimised for economical cast-iron machining
• Rhombic 16 mm plate with 35° cutting angle
• 0.8 mm corner radius for stable cuts

Higher productivity through a coating and grade matched to cast iron

The CVD-coated carbide T505 grade delivers a balance between wear resistance and economy when machining grey and nodular cast iron. The CVD-coated surface improves abrasion resistance and supports stable cutting at recommended speeds, which reduces the frequency of tool changes and contributes to lower machining costs over time. Choosing the correct chipbreaker CM for the workpiece stability and the type of cut (continuous or interrupted) ensures consistent chip control and surface quality. This combination leads to measurable efficiency gains in series production and jobbing work.

Faster set-ups and repeatable clamping with ISO conformity

The insert is an ISO-type plate, so compatibility with holders is governed by plate geometry, clearance angle (7°), tolerance class, fastening method, plate size and thickness. The rhombic shape and 35° cutting edge angle allow favourable approach geometry for both facing and turning profiles, while the central hole with a cylindrical bore and a single-sided countersink (40°–60°) enables secure clamping and straightforward indexation. Using ISO-compliant clamping systems and the correct shim or clamping set reduces set-up time and guarantees repeatable positioning for series work.

Robust edge strength and predictable tool life for stable machining

A 0.8 mm corner radius provides additional edge strength, improving performance in heavier cuts and when machining interrupted surfaces. The plate thickness of 4.76 mm and the overall 16 mm plate dimension contribute to mechanical stability in the seat, reducing vibration and improving surface finish. The grade and geometry combination supports steady cutting forces, which translates into longer effective tool life and fewer tool changes — a clear economic advantage. The insert forms part of a system that includes a matching external holder or boring bar, shims/clamping sets and spare screws to maintain productivity on the shop floor.

FAQ

What materials is this insert best suited for?

The VCMT160408-CM T505 is formulated for economical machining of cast iron; the CVD-coated T505 grade provides wear resistance and good chip control when turning cast-iron components.

How does the 0.8 mm corner radius affect performance?

A 0.8 mm corner radius increases edge strength and stability, helping the VCMT160408-CM T505 withstand heavier cuts and interrupted cuts while improving surface finish consistency.

Which holders are compatible with this ISO plate?

Compatibility is determined by plate shape, clearance angle (7°), tolerance class, fixing method, size and thickness; use ISO-compliant holders specified for rhombic VCMT 16 mm plates and ensure correct shim and clamping hardware.

Is the insert suitable for internal boring as well as external turning?

Yes; the rhombic geometry and 35° cutting angle make the insert adaptable for both external and internal turning operations when paired with an appropriate boring bar or holder.

What does the CM chipbreaker support?

The CM chipformer is optimised for chip control in typical cast-iron turning applications; selection should consider workpiece stability, feed and whether the cut is continuous or interrupted.
