SNMG 190612 T5115 — Turning insert by Tungaloy, CVD-coated carbide

SNMG 190612 T5115 is an ISO-conforming indexable turning insert for external and internal turning applications, optimised for machining cast iron with balanced wear resistance and edge stability

• Universal grade T5115 for cast iron applications
• ISO indexable geometry for standard holders
• Square 19 mm form with 1.2 mm corner radius
• Double-sided chipbreaker for economical use

Consistent wear resistance for productive cast-iron turning

The CVD-coated T5115 grade combines a wear-resistant coating with a tough carbide substrate to maintain cutting-edge stability under intermittent and continuous cuts. This balance reduces flank wear and helps preserve surface finish over longer tool life, which in turn lowers tool-change frequency and supports uninterrupted production cycles. With a focus on measurable performance, the result is a predictable process window and improved component repeatability.

Easy specification and secure clamping in ISO systems

Designed as part of the ISO indexable turning insert family, compatibility is defined by geometry, relief angle, tolerance class, fastening method, overall size and thickness. The insert features a square 19 mm form, 6.35 mm thickness and a 1.2 mm corner radius, together delivering stiffness for heavier cuts and stable support in the pocket. The cylindrical hole provides positive seating and reliable clamping when used with an appropriately matched holder and clamping set.

Chip control and operational economy

The double-sided chipbreaker profile enables reuse of both cutting edges, lowering per-edge cost and reducing inventory needs. The neutral relief (0°) and the 90° included angle make the insert versatile for both external and internal turning where a balanced cut is required. The CVD coating enhances resistance to built-up edge and abrasion; because it is a chemical vapour deposition layer, it adheres strongly to the carbide and is particularly effective when machining grey and ductile cast irons, providing a stable cutting action and consistent surface quality.

Practical integration in production workflows

When planning tool assemblies, choose a matching ISO holder that corresponds to the insert's form and dimensions to ensure correct seat and rake relationship. The insert’s geometry permits straightforward indexing and replacement, supporting faster set-ups and reduced downtime. For process engineers seeking predictable results, the combination of CVD-coated carbide and a defined chipbreaker design delivers a measurable improvement in tool life and machining consistency.
