CNMA 120412 TH10 CNMA120412 TH10 Tungaloy indexable insert — ISO turning insert, 80° rhombic, 1.2 mm radius

A CNMA120412 TH10 indexable turning insert for ISO‑standard external and internal turning, rhombic 80° geometry with a cylindrical mounting hole for predictable seating and repeatable clamping.

• ISO‑compliant rhombic 80° insert
• Sharp uncoated carbide TH10 grade
• 1.2 mm corner radius for precise contours
• Cylindrical mounting hole, no chipbreaker

Precision fit for secure, repeatable clamping

The ISO‑standardised geometry ensures a predictable fit with compatible holders: the rhombic 80° form, the specified 1.2 mm corner radius and the cylindrical hole combine to deliver consistent seating and repeatable clamping. This reduces setup variance and supports steady production runs. Compatibility depends on holder form, clearance angle, tolerance class, fixing method and plate thickness, so selection within the ISO system simplifies tool management and reduces inventory complexity.

Low cutting forces and clean surface finish with TH10

The TH10 designation describes a sharp, uncoated carbide grade optimised for non‑ferrous materials and light‑cut applications. An uncoated substrate provides a keen cutting edge that minimises built‑up edge and delivers low cutting forces, which in turn improves tool life when machining softer alloys and enhances surface integrity on sensitive components. For operations prioritising neat finishes and reduced burr formation, this grade offers a practical balance between edge sharpness and wear resistance.

System advantages for external and internal turning

As part of an ISO turning system — indexable plate, matching outer holder or boring bar, clamp/support and spare screws — the insert supports fast index changes and economical reconditioning of cutting edges. The absence of an integrated chipbreaker means chip control must be matched to material and machining stability, but it also allows cleaner contours in finishing passes. For turning tasks where minimal cutting forces and a sharp edge are decisive, this insert contributes to improved process stability and productive throughput.

FAQ

What materials is this insert primarily intended for?
The CNMA120412 TH10 insert from Tungaloy is primarily intended for non‑ferrous materials and applications where a sharp, uncoated cutting edge supports low cutting forces and clean surface finishes.

How does the absence of a chipbreaker affect application?
Without a chipbreaker, chip control must be achieved through process parameters and appropriate holder selection; the CNMA120412 TH10 insert is therefore best used where machine stability and tailored cutting conditions are available.

Is the insert compatible with standard ISO turning holders?
Yes, the insert follows ISO geometry; compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness—ensure holder specifications match the insert’s rhombic 80° form and 4.76 mm thickness.

What is the significance of the TH10 grade?
TH10 denotes a sharp, uncoated carbide grade engineered to deliver low cutting forces and good surface quality on softer and non‑ferrous alloys; it balances edge sharpness with acceptable wear resistance for finishing operations.

Which SKU or article number identifies this product?
The product is listed under article number 6801925 and manufacturer SKU TUN6801925; it is an ISO‑standard CNMA120412 TH10 indexable turning insert by Tungaloy.
