SNMG190616 T515 SNMG – ISO turning insert for Drehen by Tungaloy

The SNMG190616 T515 is an ISO-standardised square turning insert for external and internal turning, designed for economical machining of cast iron with a 90° approach angle and a 1.6 mm corner radius.

• CVD-coated carbide for economical cast-iron machining
• ISO-standard SNMG insert, 90° approach angle
• Double-sided chipbreaker for quick indexability
• Square 19 mm size, 6.35 mm thickness

Stable, economical cutting for cast-iron components

The CVD-coated carbide grade T515 provides a balance between cost-effectiveness and reliable edge life, making it suitable where consistent production rates are required. The coating supports stable chip formation, reducing built-up edge and improving component finish; this is particularly beneficial when turning grey or nodular cast iron. By combining a durable substrate with an engineered surface layer, the insert reduces the frequency of tool changes and keeps cycle times predictable on series production.

Geometry and system compatibility that reduce setup time

With a 90° approach angle, square format and a 1.6 mm corner radius, the insert offers both rigidity and versatility for facing and general turning tasks. The double-sided chipbreaker reduces indexing time and lowers tooling cost per cutting edge. Compatibility with toolholders depends on form, clearance angle, tolerance class, fixing method, size and thickness, so using ISO-standard holders and the correct clamp set ensures accurate seating and repeatability in the toolpost or boring bar.

Process security and surface quality thanks to coherent design

The combination of CVD-coated surface and the chipbreaker geometry promotes secure chip evacuation and a stable cutting edge, which contributes to improved surface finish and fewer rejects. For interrupted cuts or unstable setups, selecting the appropriate chipbreaker and ensuring sufficient workpiece rigidity will extend tool life. The grade is optimised for cast-iron turning where a balance of productivity and edge stability matters most.

Practical handling and spare-part considerations

Dimensioned as a square insert with a 19 mm side and 6.35 mm thickness, the item is delivered in the SNMG190616 form with a cylindrical hole for positive clamping. The system concept typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement screws; keeping spare screws and shims on hand reduces machine downtime and simplifies changeover in production.

FAQ

Which materials is this insert best suited for?
The SNMG190616 T515 by Tungaloy is formulated primarily for economical machining of cast iron; the CVD-coated carbide and chipbreaker geometry favour stable operation in grey and nodular cast irons.

Is the insert reversible and indexable?
Yes, the SNMG190616 is double-sided and indexable; the chipbreaker on both faces allows rapid indexing to a fresh cutting edge, improving cost-efficiency per edge.

How do the geometry and coating affect surface finish?
The combination of the CVD-coated substrate and the chipbreaker supports controlled chip flow and a stable cutting edge, which together help achieve consistent surface quality in routine turning operations.

What dimensions and mounting features should be checked before ordering?
Key dimensions are a 19 mm side, 6.35 mm thickness and a 1.6 mm corner radius; the insert has a cylindrical hole and requires a matching ISO holder with the correct clearance and tolerance class for secure mounting.

Can the SNMG190616 T515 be used for interrupted cuts or unstable setups?
It can be used, but selection of the chipbreaker and ensuring workpiece and toolholder stability are important; the grade is chosen for economical cast-iron machining and performs best in stable setups.
