• Double-sided chipbreaker, cylindrical hole

Precision and process reliability for turning operations

The TNMG160412 insert is an ISO-format, triangular carbide cutting solution designed for repeatable external and internal turning. Its GH330 grade combines wear resistance and useful toughness, so the insert sustains stable cutting edges under typical production loads. Compatibility with standard ISO holders is governed by form, relief angle, tolerance class, clamping method, size and thickness; this ensures secure seating and consistent cutting geometry, which in turn supports predictable dimensional results and lower scrap rates.

Geometry tailored to shape cutting behaviour and tool life

Key geometric values such as the 16 mm size, 4.76 mm thickness and 1.2 mm corner radius influence cutting entry, strength and surface finish. The 60° included angle and 0° relief angle provide a neutral profile suitable for a wide range of turning tasks, while the triangular form allows two usable edges per side. The integrated double-sided chipbreaker and cylindrical locating hole support effective chip control and straightforward clamping, reducing vibration and promoting longer edge life when matched with an appropriate holder and cutting parameters.

System approach and economical indexing

Used as part of an ISO insert system—comprising the indexable insert, a suitable external holder or boring bar, a shim/clamping set and spare screws—the insert enables rapid index changes and minimal setup times. Indexability and double-sided design make the solution cost-effective in batch production: service intervals are extended and machine downtime is reduced. Selection of the correct chipbreaker and grade should be guided by the workpiece material, machining stability and required surface quality to achieve the best balance between productivity and tool life.

Application guidance and quality assurance

For robust roughing where edge strength is paramount, the 1.2 mm corner radius helps absorb intermittent loads; for fine finishing, consider smaller radii or adjusted cutting parameters to meet surface tolerance demands. The GH330 grade from Tungaloy is optimised to provide a dependable mix of hardness and resistance to wear, supporting consistent results across many turning scenarios. If there is any uncertainty about holder compatibility or best-practice cutting data, practical guidance can be provided to align the insert choice with the machining context.
