• CVD‑coated carbide grade T9225
• 60° geometry with 1.6 mm corner radius
• Double‑sided chipbreaker, cylindrical hole

Reliable grade for demanding steel turning

The CVD‑coated carbide T9225 is formulated as a robust universal grade for medium to heavy steel machining, offering a balance of hardness and toughness. Its composition supports stable chip formation under varying engagement conditions and provides enhanced resistance to flank wear during longer cuts. For operations with slight interruptions or variable cutting forces, the grade’s increased toughness reduces the risk of chipping and extends tool life, resulting in fewer indexings and improved production efficiency. The insert model TNMG220416 is therefore suited to workshops that require predictable performance across a range of steel materials.

Precise geometry that simplifies setup and improves surface finish

The triangular 60° geometry with a 1.6 mm corner radius and a plate thickness of 4.76 mm gives stable support in the holder while allowing controllable chip load and good surface integrity. The ISO standard form ensures compatibility with many external holders and boring bars; however, correct matching depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole and double‑sided design enable straightforward clamping and economical indexability. For machinists, this means faster tool changes, consistent runout behaviour and reduced setup time when integrating into existing tool systems.

Practical system benefits for workshop productivity

In a typical system build the indexable plate pairs with a suitable external holder or boring bar, plus a shim/clamping set and spare screws, enabling a complete turning solution without complex adjustments. The double‑sided chipbreaker supports reliable chip control in external and internal turning and reduces the need for secondary operations caused by poor chip evacuation. Together, these characteristics enhance process stability and can lower total machining costs through longer tool life, fewer interruptions and improved component repeatability. Clear specification and consistent material compatibility make this insert a dependable choice for daily production work.
