CCMT 120412 T9225 turning insert (CCMT120412, Tungaloy) — ISO rhombic insert for medium to heavy steel turning

CCMT120412 T9225 is an ISO-standard rhombic turning insert designed as a robust universal grade for demanding steel turning applications

• CVD-coated carbide for durable performance
• Universal grade for medium to heavy steel
• Rhombic CCMT form with cylindrical hole + countersink
• 1.2 mm corner radius for strength and stability

Reliable cutting performance under variable conditions

The T9225 grade combines a CVD-coated carbide substrate with a formulation tuned for toughness, making it suitable for medium to heavy steel turning where varying engagement or intermittent cuts occur. The tougher grade reduces the risk of chipping during interrupted cuts and supports longer edge life, which in turn decreases unplanned tool changes and downtime. The included chipbreaker geometry is chosen to match stability and the required surface finish, so selecting the correct chip control variant ensures repeatable results and enhanced process efficiency.

Seamless integration into ISO turning systems

Designed to the ISO designation, the insert fits standard holders when form, 7° clearance angle, tolerance class, clamping method, size and thickness are matched. The CCMT form and cylindrical hole + countersink (40°–60°) allow secure clamping with common outer holders or boring bars, while the 4.76 mm thickness provides a stable support plane under load. These dimensional standards simplify toolroom logistics and make replacement straightforward, reducing set-up time and ensuring the insert runs true in appropriately specified tooling systems.

Higher productivity with predictable maintenance cycles

A 1.2 mm corner radius offers a balanced compromise between strength and edge definition, supporting deeper cuts with improved vibration resistance and consistent surface quality. Using the insert as part of a complete system — insert, compatible holder, shim/clamping set and spare screws — promotes predictable maintenance intervals and eases inventory management. The robust universal composition of the grade means fewer insert variants are required across a range of steel components, which optimises stockholding and boosts overall production throughput.

FAQ

What materials is this insert designed for?
The CCMT120412 T9225 turning insert is formulated for steel, particularly medium to heavy steel turning where toughness and stable chip control are required.

Will this insert fit standard CCMT holders?
Yes — the insert follows ISO dimensions; compatibility depends on matching form, 7° clearance angle, thickness (4.76 mm) and clamping style to the holder.

Which cutting conditions suit the T9225 grade best?
T9225 is optimised for variable engagement and lightly interrupted cuts in steel, offering good edge strength and consistent tool life under mixed conditions.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius improves edge robustness and vibration resistance, enabling deeper cuts and more stable finishing while balancing surface quality and tool life.
