TPMR 160312 T5115 Tungaloy indexable turning insert — ISO triangular insert for turning

A TPMR160312-CM T5115 indexable insert designed for ISO-compliant turning operations, optimised for external and internal turning of cast iron with a CM chipbreaker.

• CVD-coated carbide for wear resistance
• Universal grade T5115 for cast iron
• 60° triangular insert with 1.2 mm radius
• ISO-compliant, 3.18 mm plate thickness

Productivity through a balanced grade and coating

The combination of a CVD-coated carbide substrate and the T5115 grade delivers a balanced compromise between wear resistance and edge stability, which is particularly valuable when machining grey and nodular cast iron. This balance reduces unexpected tool changeovers and promotes predictable component quality across batch production. The CM chipbreaker helps to control chip form during interrupted or continuous cuts, contributing to shorter cycle times and improved process reliability.

Defined geometry for reliable fit and surface quality

ISO conformity means the insert’s compatibility with a holder is governed by its shape, relief angle, tolerance class, clamping method, size and thickness. The triangular geometry with a 60° included angle and a 1.2 mm nose radius offers a compromise between strength and surface finish; a larger radius increases edge strength for heavier cuts, while the specific 11° relief angle supports stable contact with the workpiece. Using ISO-matching clamping elements and shims keeps the cutting edge position reproducible, which is essential for repeatable tolerances in production environments.

Practical application and benefits for workshop efficiency

Intended for external and internal turning, this ISO insert is best paired with a suitable external holder or boring bar and the corresponding shim/clamping set and replacement screws to complete the system. As an indexable insert, it reduces downtime compared with brazed or solid tooling since edges can be rotated or replaced rapidly. The universality of the T5115 grade simplifies inventory management for mixed-cast-iron shops, while the CVD layer extends intervals between interventions — a direct contribution to lower running costs and steady output.

FAQ

What materials is this insert suitable for?
The TPMR160312-CM T5115 insert is specified as a universal grade for cast iron, offering a mix of wear resistance and edge stability suitable for grey and nodular cast iron applications.

How does the CM chipbreaker affect machining?
The CM chipbreaker on this indexable insert promotes manageable chip formation and evacuation during turning of cast iron, helping to maintain surface quality and reduce the risk of chip-related interruptions.

Which geometry aspects determine holder compatibility?
Compatibility is determined by the insert’s shape, relief angle (11°), tolerance class, clamping style, size (16 mm) and thickness (3.18 mm); matching these parameters with an ISO-compliant holder ensures correct mounting and cutting position.
