CCMT 09T302 T9225 – ISO turning insert for steel, Tungaloy

The CCMT 09T302 T9225 is an ISO rhombic turning insert engineered for external and internal turning of steel, offering a CVD-coated carbide grade designed for stable chip formation and reliable performance under variable engagement conditions.

• CVD-coated carbide for improved wear resistance
• Universal T9225 grade for medium–heavy steel
• Rhombic CCMT form with 0.2 mm corner radius
• Cylindrical hole with 40°–60° countersink

Extended tool life from a CVD-coated universal grade

The CVD-coated T9225 carbide provides a balance of hardness and toughness that is particularly beneficial for medium to heavy machining of steel. The coating improves wear resistance and heat tolerance, which reduces flank wear and extends edge life under demanding conditions. This performance translates directly into fewer insert changes and higher machine uptime, delivering a measurable improvement in process economy while maintaining consistent cutting forces and surface integrity.

Secure seating and ISO compatibility for process stability

Designed to ISO dimensions, the rhombic CCMT shape ensures interchangeability with compliant holders; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert features a 7° relief and an 80° included angle that promote predictable contact geometry and repeatable clamping. The cylindrical hole with a single-sided countersink (40°–60°) guarantees accurate seating and secure clamping, which is essential for avoiding micro-movements that can shorten tool life or degrade surface finish.

Controlled chip formation for interrupted and variable cuts

The one-sided chipbreaker and the 0.2 mm corner radius support stable chip control across changing engagement conditions. This makes the insert suitable for slightly interrupted cuts or operations where engagement varies, as the grade’s toughness absorbs impacts while the chipformer manages evacuation. For best results, match the chipbreaker and cutting data to workpiece stability and fixture rigidity; the insert forms part of a system that includes the appropriate holder, shim or clamp set and fastening screws to maintain consistent process parameters.

Practical application guidance for workshop efficiency

When integrating the insert into a production cell, selecting a holder compatible with the CCMT form and the specified 3.97 mm thickness ensures optimal load distribution. The universal nature of the grade reduces the need for multiple specialised inserts, simplifying inventory and enabling rapid job changeovers. Clear labelling of insert designation and stock-keeping unit helps maintain traceability and repeatability across batches, supporting both small-series flexibility and larger-volume throughput.

FAQ

Is this insert suitable for interrupted cuts?
The CCMT 09T302 T9225 insert is formulated for slightly interrupted cuts; the T9225 grade offers increased toughness while the chipbreaker aids reliable chip control during variable engagement.

Which workpiece materials are recommended?
The insert is optimised for steel machining; the CVD-coated carbide and universal grade are chosen to balance wear resistance and toughness for medium to heavy steel operations.

How does the hole and countersink affect clamping?
The cylindrical hole with a 40°–60° single-sided countersink ensures precise seating and consistent clamping force, improving repeatability and reducing the risk of insert movement during turning.

What holder characteristics are required for correct fitment?
Compatibility is governed by insert form, relief angle, tolerance class, fastening method, size and thickness. A holder matching the CCMT form and 3.97 mm thickness is required for secure and accurate clamping.

Can one insert grade cover multiple jobs?
The universal T9225 grade is intended to cover a broad range of medium-to-heavy steel turning tasks, simplifying tooling inventory and enabling faster job changeovers.
