CNGN120712 TS300 ISO turning insert — Tungaloy, rhombic 80° geometry

The CNGN120712 TS300 is an ISO‑standard rhombic indexable insert designed for external and internal turning, engineered to combine wear resistance with cutting‑edge stability for general turning tasks.

• ISO‑compliant rhombic insert
• TS300 wear‑resistant grade
• 80° seating angle for secure clamping
• 1.2 mm corner radius for strength and finish

Stable performance through material and grade selection

The combination of a carbide substrate with the TS300 cutting grade provides a reliable balance of wear resistance and toughness, which reduces edge failure during interrupted cuts. The specialised grade complements the insert geometry to ensure steady cutting forces and extended tool life when machining a broad range of steels and alloyed materials. By choosing this insert, operations benefit from predictable tool behaviour and fewer unexpected tool changes, supporting higher process efficiency and reduced downtime.

Rigidity and surface quality for consistent turning

An insert thickness of 7.94 mm and an 80° seating geometry increase clamping stability in suitable holders, lowering vibration and improving surface finish during both external and internal turning. The 1.2 mm corner radius offers a compromise between edge strength and the ability to achieve good surface integrity; a larger radius boosts edge life, while a smaller one improves profile accuracy. These measurable characteristics translate directly into fewer rework cycles and steadier cycle times on production lines.

System compatibility and application guidance

The ISO designation encapsulates form, size and tolerance: a rhombic CNGN form with the 120712 size ensures straightforward matching with ISO‑compatible external holders or boring bars; the insert is supplied without a hole and has a 0° clearance angle, so the correct clamp or seat must be selected for secure fixation. Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness—verify these parameters when replacing inserts. The insert suits general turning; chipbreaker selection should be matched to the workpiece material, machining strategy and machine stability to optimise chip control.

Practical benefits and machining recommendations

Using a purpose‑matched insert delivers concrete economic benefits: longer uninterrupted cutting times, fewer tool changes and improved reproducibility of component quality. For general turning, pair this indexable insert with a rigid holder and adapt feed and speed to material and machine dynamics. If machining unstable setups or heavy interrupted cuts, select a geometry or chip control solution that prioritises edge strength. Clear labelling and ISO conformity simplify tool management and inventory control across production sites.

FAQ

What materials is this insert suitable for?
The CNGN120712 TS300 insert is formulated for a wide range of steels and alloyed materials; the TS300 grade provides balanced wear resistance and toughness for general turning tasks.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius increases edge strength and contributes to improved surface finish under stable cutting conditions when using the CNGN120712 TS300 insert.

Is the insert compatible with standard ISO holders?
Yes — the ISO designation indicates compatibility with ISO‑compliant external holders or boring bars that match form, size, thickness and fastening method for the CNGN120712 TS300.

Does this insert include a chipbreaker?
This particular insert is supplied without a chipbreaker; chip control should be addressed via geometry selection or matched peripheral tooling depending on the application.
