SNMG 120402 T6215 SNMG120402 — Indexable turning insert for Turning, Tungaloy

SNMG120402 T6215 is a square ISO indexable insert designed for turning applications, optimised for rostfreier Stahl under stable to slightly interrupted cutting conditions

• CVD-coated carbide for rostfreier Stahl
• ISO-compliant SNMG120402 geometry
• Double-sided chipbreaker for stability
• Square insert with 90° cutting edge

Consistent cutting performance for rostfreier Stahl

The insert’s CVD coating and carbide substrate form a wear-resistant system that keeps edge integrity under demanding conditions. For machining rostfreier Stahl, the T6215 grade balances toughness and abrasion resistance to reduce flank wear and thermal softening. The 90° square form provides predictable chip flow and stable cutting forces; this leads to reproducible component quality and longer indexable life. Operators gain measurable process stability, not just nominal tool life.

Secure fit and predictable geometry for reliable clamping

Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening and plate thickness. The ISO designation ensures interchangeability: the SNMG120402 format, cylindrical hole and standard tolerance allow secure clamping in most external holders and toolholders. The 0.2 mm corner radius and 4.76 mm plate thickness contribute to a robust cutting edge and consistent seating, reducing the risk of insert movement during interrupted cuts and improving repeatability in serial production.

Coating and grade advantages that extend productive time

A CVD-coated hardmetal grade like T6215 combines a hard surface layer with a tough substrate to resist abrasion while withstanding chatter and edge chipping. The double-sided chipbreaker design promotes controlled chip formation across a range of feeds and depths, simplifying process setup and reducing manual intervention. This results in fewer index changes and a higher share of productive machining time — a clear cost-efficiency argument for batch and continuous turning operations.

Application guidance and selection criteria

When using this insert for turning, select the chipbreaker and grade according to workpiece material, machining type and machine stability. For stable to lightly interrupted turning of rostfreier Stahl, the combination of the SNMG geometry and T6215 grade suits external and internal turning operations. Ensure the holder matches the insert’s form, 0° clearance angle, hole style and thickness to maintain clamping integrity. For borderline conditions, a toolholder with additional support or different insert seating may further improve process security.
