Higher productivity with the sharp TH10 grade

The TH10 grade is an uncoated, sharp universal carbide designed to reduce cutting forces and support cleaner part surfaces when machining non-ferrous materials. By lowering cutting resistance, the grade contributes to reduced tool-induced vibration and more consistent chip formation, which in turn helps maintain cycle times and improves repeatability in production environments. For workshops seeking reliable performance in light-to-medium stability set-ups, this characteristic makes the insert particularly effective at delivering stable feeds and improved surface integrity on aluminium alloys, brass and similar materials. The result is an efficient process that balances cutting efficiency with achievable surface quality.

Secure clamping and ISO compatibility for repeatable results

The insert’s geometry — a rhombic CNMG form with an 80° included angle and a cylindrical hole — ensures dependable mounting in standard external holders and boring bars. Compatibility with a given holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters guarantees correct seating and repeatable tool overhang and orientation. The ISO standard designation simplifies procurement and replacement in production lines, while the rhombic shape provides flexibility for both facing and general turning tasks. This combination supports predictable cutting conditions and reduces set-up variability across batches.

Design features that support chip control and finish

Built with a double-sided chipbreaker and a corner radius 1.2 mm, the insert assists in producing controlled chip forms and improved part faces during turning. The chipbreaker is tailored to promote short, manageable chips at typical feeds for non-ferrous materials, lowering the likelihood of entanglement and easing post-process handling. The corner radius balances edge strength and surface finish: a 1.2 mm radius provides a robust cutting edge while helping to achieve consistent surface appearance at standard finishing feeds. Together these attributes reduce process interruptions and support higher first-pass yield rates.

System setup and practical guidance for turning operations

The CNMG insert should be used as part of a system comprising the ISO insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws. Choose the chipbreaker and grade according to workpiece material, machining strategy and machine stability; for non-ferrous and delicate operations the uncoated sharp grade proves advantageous due to lower adhesion tendency and cleaner surfaces. If additional clarification is required about holder selection or insert orientation, technical documentation and cutting data can be provided.

FAQ

Which materials is this insert best suited for?
The TH10 grade is optimised for non-ferrous materials; the CNMG120412 TH10 insert from Tungaloy performs well on aluminium alloys, brass and similar workpiece materials where low cutting forces and clean surface demands are required.

How does the TH10 grade influence cutting performance?
The TH10 uncoated carbide grade provides a sharp cutting edge that reduces cutting forces and supports cleaner surfaces; users of the CNMG120412 TH10 will typically see improved chip formation and reduced burrs in compatible materials.

Is the CNMG120412 compatible with standard CNMG holders?
Yes; compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness — when these parameters match, the CNMG120412 TH10 insert seats correctly in standard CNMG holders and boring bars.

What benefits does the double-sided chipbreaker provide?
The double-sided chipbreaker on this insert promotes controlled chip formation and easier chip evacuation, which helps maintain process stability and reduces the risk of chip-related interruptions during turning.

Can the corner radius be changed for different surface finish requirements?
The supplied insert has a corner radius of 1.2 mm; for finer finishes or different mechanical demands, select an alternative radius from compatible ISO CNMG options that match the required machining strategy.
