CPMT09T304 T9225 Turning insert (CPMT 09T304) by Tungaloy

CPMT09T304 is an ISO-design turning insert for medium‑to‑heavy steel machining, offering a robust universal grade and standardised geometry for easy integration into common holder systems.

• ISO-compliant rhombic insert
• CVD-coated carbide T9225
• Single-sided chipbreaker
• 3.97 mm thickness, 0.4 mm radius

Reliable cutting performance for medium–heavy steel turning

The CPMT09T304 indexable insert combines a CVD-coated carbide substrate with the T9225 grade to deliver a balance of hardness and toughness that suits variable engagement conditions. This grade is engineered for medium to heavy steel machining, where occasional interruptions or changes in cut depth demand increased edge resilience. The coating enhances wear resistance, while the carbide core maintains strength at elevated cutting temperatures, resulting in consistent cutting performance and reduced frequency of insert changes.

ISO geometry that eases set-up and compatibility checks

The rhombic design and ISO designation guarantee predictable fitting in ISO-compatible toolholders. Key geometric parameters such as the 11° relief angle, 80° approach angle, and 3.97 mm thickness determine seating and cutting kinematics; these standardised values simplify selection of the matching holder, shim and clamping set. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness, so matching these characteristics ensures secure clamping and repeatable results across production runs.

Controlled chips and secure clamping for reliable machining

A single-sided chipbreaker delivers directed chip control for many turning operations, improving chip evacuation and surface finish on both external and internal turning. The insert’s cylindrical hole with a single-sided countersink (40°–60°) facilitates positive, repeatable clamping with the usual screw and clamp assemblies; a correct clamping set-up minimises micro-movements that cause edge breakouts. Explaining briefly, a chipbreaker alters the chip flow near the cutting edge to reduce entanglement and heat concentration, which supports longer edge life and safer handling at higher material removal rates.

Practical workshop advantages and application guidance

Adopting this ISO insert supports shop-floor productivity by reducing unpredictable tool changes and enabling stable process windows, which translates into less downtime and longer tool life. For optimum results, pair the insert with a holder geometry suited to the desired approach angle and rigidity, and choose cutting parameters considering the robust universal nature of the T9225 grade. Where interrupted cuts or variable stock conditions occur, the grade’s increased toughness helps maintain tool integrity and repeatable part accuracy.

FAQ

Which materials is this insert intended for?
The CPMT09T304 insert in grade T9225 is designed primarily for steel machining, especially medium to heavy operations where toughness is required.

How well does the T9225 grade handle interrupted cuts?
Tungaloy’s T9225 CVD-coated carbide offers enhanced toughness for interrupted or unstable cuts, helping to preserve edge integrity on the CPMT09T304 indexable insert (SKU 6781289-Tungaloy).

What must be considered when choosing a compatible holder?
Holder compatibility is determined by the insert’s form, 11° relief angle, tolerance class, fastening method, size and thickness; matching these parameters with the toolholder and clamp set ensures secure seating and repeatable performance.

Can this insert be used for internal turning operations?
Yes, the geometry and chip control of this rhombic insert make it suitable for both external and internal turning applications when paired with the correct holder.

What chip control features does the insert provide?
The single-sided chipbreaker on this insert guides chip flow away from the workpiece and cutting zone, improving evacuation and surface finish while reducing the risk of chip entanglement.
