CNGN 120408 TS300 ISO turning indexable insert for external and internal turning — Tungaloy

A robust CNGN120408 TS300 indexable insert engineered for general turning applications, designed to fit ISO-compatible holders and deliver predictable machining results.

• ISO‑compliant CNGN geometry for standard holders
• TS300 Tungaloy grade for wear resistance
• Rhombic 80° form, 12 mm inscribed circle
• 0.8 mm corner radius for fine finishing

Seamless integration with ISO tool systems for reliable workflows

The insert has been developed for the ISO model series and is intended to integrate easily into established turning tool systems. Compatibility is defined by shape, relief angle, tolerance class, clamping method, size and thickness, which allows planners to select holders and clamping sets with predictability. With an inscribed circle of 12 mm and a thickness of 4.76 mm, the insert fits common small‑to‑medium modular holders, reducing setup time and simplifying inventory. The standardised form keeps process variability low and helps maintain a steady production flow.

Optimised grade and substrate for extended tool life and edge stability

The TS300 cutting grade from Tungaloy combines a hard substrate with a formulation designed to favour wear resistance while retaining sufficient toughness for turning operations. Manufactured from cemented carbide, the grade aims to balance flank wear and chipping resistance so that cutting edges remain stable over longer cycles. The 0.8 mm corner radius supports improved surface finish and controlled cutting forces in finishing passes, whilst the absence of an integrated chipbreaker means the geometry is best matched with workpiece material and stability considerations when selecting machining parameters.

Practical shop‑floor benefits: handling, clamping and application scope

Designed for both external and internal turning, the rhombic 80° form provides accessibility in shoulder cuts and facing operations while maintaining a secure clamping interface. The insert is supplied without a hole, so it is intended for seat‑clamp or top‑clamp holders compatible with the CNGN form; matching shim/clamp sets and replacement screws should be checked for fit. Because the insert’s 4.76 mm thickness contributes to mechanical rigidity, it supports stable cutting in typical lathe setups and is suited to operations where consistent chip control and repeatable dimensions are required.

FAQ

What materials is this insert suitable for?
The TS300 grade is formulated for a broad range of turning applications; the CNGN120408 TS300 insert performs well where wear resistance and edge stability are required, with the final suitability depending on workpiece material and cutting conditions.

Which holder type is required for a CNGN insert without a hole?
A seat‑clamp or top‑clamp holder designed for CNGN geometry is required for the CNGN120408 TS300 insert; ensure the holder matches the relief angle, tolerance class and plate thickness.

How does the 0.8 mm corner radius affect surface finish?
The 0.8 mm corner radius on the insert promotes improved surface finish during finishing passes by reducing cutting pressure peaks and offering a more robust edge for consistent dimensional results.

Is a chipbreaker integrated on this insert?
This variant is supplied without a chipbreaker; chip control should be managed via cutting parameters and selection of an appropriate grade or separate chip management strategy.

What system components are recommended for using this insert?
A complete system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and spare screws; verify mechanical fit before production runs.
