DCMT070204 T5115 ISO Turning Insert for Cast Iron — Tungaloy

DCMT070204 T5115 is an ISO-format indexable turning insert designed for external and internal turning of cast iron components, offering a balance of wear resistance and edge stability for industrial machining.

• CVD-coated carbide for improved wear resistance
• Optimised for cast iron turning applications
• Rhombic 07 shape with 7° clearance angle
• Central hole with cylindrical recess, 40°–60° countersink

Precision fit and predictable clamping for routine production

The insert is part of an ISO turning insert system where compatibility is defined by shape, 7° clearance angle, tolerance class, fastening method, size and thickness. This set-up delivers predictable seating in standard holders and repeatable tool geometry, reducing set-up time and variation between inserts. Clear, standardised dimensions mean that toolroom engineers and production planners can allocate inserts to existing ISO holders without trial-and-error, supporting uninterrupted turning cycles and consistent part quality.

Coating and grade engineered for cast iron performance

The T5115 grade combines a CVD-coated carbide substrate with a universal profile aimed at cast iron machining. The coating improves wear resistance while the substrate maintains a stable cutting edge, which helps sustain surface finish and dimensional accuracy under interrupted or continuous cuts. For operations where tool life and surface integrity are critical, this balance often results in fewer indexings and less scrap, providing a measurable productivity gain over uncoated or lower-grade alternatives.

Geometry that controls chips and secures the insert

With a 0.4 mm corner radius, single-sided chipbreaker and a rhombic 07 outline, the insert supports stable cutting forces and predictable chip formation on typical cast iron workpieces. The central hole with a cylindrical recess and one-sided countersink (40°–60°) provides secure clamping and repeatable seating in compatible toolholders. These features reduce vibration and protect the cutting edge, which contributes to improved tool life and cleaner parts straight from the lathe.

Operational benefits and return on process stability

Choosing this insert delivers tangible operational benefits: improved tool life, consistent surface finish and reduced machine downtime from fewer insert changes. The geometry and coating make it suitable for both roughing and finishing passes when matched with an appropriate holder and cutting data. Where process reliability and throughput matter most, integrating standardised ISO inserts like this one supports predictable cycle times and easier inventory management across the production floor.

FAQ

What materials is this insert suitable for?
The DCMT070204 T5115 insert from Tungaloy is formulated primarily for cast iron machining; the T5115 CVD-coated carbide grade provides balanced wear resistance and edge stability for a broad range of grey and nodular cast irons (SKU 6864770-Tungaloy).

Can this insert be used for internal turning as well as external turning?
Yes, the geometry and single-sided chipbreaker make the insert suitable for both external and internal turning operations when paired with a compatible ISO holder; refer to the DCMT070204 T5115 specification for holder compatibility and clamping requirements.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius offers a compromise between strength and finish: it helps protect the cutting edge during interrupted cuts while still achieving a good surface quality on cast iron components when appropriate feeds are selected.

What does the central hole and countersink provide?
The central cylindrical hole with a one-sided countersink (40°–60°) ensures secure and repeatable clamping in standard indexable insert holders, which improves stability and reduces the risk of insert movement under load for the DCMT070204 T5115 insert.

Is the T5115 grade resistant to abrasive wear?
The T5115 CVD-coated carbide grade provides enhanced wear resistance compared with uncoated substrates; this improves performance in abrasive cast iron applications and contributes to longer tool life for the insert (manufactured by Tungaloy).
