CCMT09T308 T9225 — ISO rhombic turning insert for medium-to-heavy steel by Tungaloy

The CCMT09T308 T9225 is an ISO rhombic turning insert designed for external and internal turning operations in steel, offering a single-sided chipbreaker, CVD coating and suitability for interrupted cuts.

• ISO CCMT 09T308 geometry
• CVD-coated carbide grade T9225
• 0.8 mm nose radius for stable cuts
• With cylindrical hole and countersink

Proven productivity and predictable tool life for steel turning

The rhombic ISO geometry with an 80° included angle and 7° relief provides a predictable contact pattern, reducing vibration and improving surface finish during turning. The combination of CVD-coated carbide and the T9225 grade yields a balance of toughness and wear resistance, meaning fewer indexings and longer productive cutting periods in medium-to-heavy steel operations. For users who require repeatable cycle times and consistent part quality, this insert delivers measurable improvements in process reliability.

System compatibility and secure clamping for stable machining

Designed as an ISO-standard indexable plate, the insert fits holders that match form, relief angle, tolerance class, fixation and thickness. The plate thickness of 3.97 mm, cylindrical hole with one-sided countersink (40°–60°) and standard 09 size ensure secure seating and reliable clamping. Proper holder and insert pairing reduces micro-movement at the cutting edge, which in turn preserves the integrity of the cutting edge and maintains dimensional accuracy on turned components — a clear advantage for batch production and precision parts.

Practical guidance for selection and machining

Select the single-sided chipbreaker and the T9225 grade when operations involve varying engagement or lightly interrupted cuts that need added toughness. The 0.8 mm nose radius is optimised for a mix of surface finish and chip control; smaller radii favour fine finishing, larger radii favour heavy stock removal. Cutting parameters should be adapted to the material and rigidity of the setup: moderate speeds and feeds deliver the best compromise between tool life and productivity in typical steel applications. For less experienced planners, this insert simplifies process design through its universal performance profile.

FAQ

What materials is this insert suited for?
The CCMT09T308 T9225 insert is optimised for medium-to-heavy steel turning; the T9225 grade offers toughness suited to variable engagement and lightly interrupted cuts.

Is the CCMT09T308 compatible with standard ISO CCMT holders?
Yes, the insert follows ISO CCMT geometry — compatibility depends on matching form, relief angle, tolerance and plate thickness to the holder.

What is the advantage of the T9225 grade?
Tungaloy’s T9225 grade combines toughness and wear resistance, making it suitable for productive steel machining where engagement conditions may change.

How does the 0.8 mm nose radius affect machining?
A 0.8 mm radius balances surface finish and edge strength; it improves stability for general turning tasks compared with a finer radius while still allowing decent surface quality.

Does the insert include a chipbreaker and a clamping hole?
Yes, the plate features a single-sided chipbreaker and a cylindrical hole with one-sided countersink for reliable clamping.
