CPMT 09T308 09T308 T9225 Turning insert (Tungaloy) — CVD-coated carbide, 0.8 mm radius

CPMT09T308 T9225 is a rhombic ISO turning insert designed for medium to heavy steel turning, compatible with ISO holders and boring bars

• CVD-coated carbide for durability
• Universal grade T9225 for steel turning
• 0.8 mm corner radius for stable engagement
• ISO 09 rhombic insert with cylindrical hole

Engineered for consistent metal removal and longer tool life

The CVD-coated carbide construction and the T9225 grade provide a balance of wear resistance and toughness that is optimised for medium to heavy steel machining. The coating reduces flank wear under sustained cutting, while the substrate grade is designed to handle variable engagement and mildly interrupted cuts without premature chipping. For production environments, this combination translates into longer effective tool life and fewer insert changes, supporting a smoother workflow and predictable machining cycles.

Geometry and clamping that improve stability and control

The rhombic geometry and 80° included angle give the insert favourable edge engagement for external and internal turning, while the 0.8 mm corner radius reduces local edge loading to help prevent vibration and edge breakage. The 11° relief angle and the insert’s mounting interface — with cylindrical hole and single-sided countersink (40°–60°) — ensure secure locating and repeatable clamping in standard ISO holders. The CPMT09T308 insert’s features together reduce the risk of incorrect seating and minimise setup-related downtime, which is advantageous in serial production and shop-floor changeovers.

Integration into a reliable turning system for controlled chips

This ISO rhombic insert is intended to be used as part of a system: an appropriate external holder or boring bar, a matching shim/clamping set and spare fastening screws complete the assembly. The one-sided chipbreaker promotes effective chip control for typical turning operations and reduces the chance of tangling or workpiece damage. In practice, choosing the correct chipformer and grade for the material and stability of the setup will lead to safer machining conditions and a cleaner surface finish, particularly when machining bars or bores where chip evacuation is critical.

Practical selection guidance for variable and interrupted cuts

The T9225 universal grade is specified for robustness under changing cutting conditions; it is a good first choice when facing mixed batches or partially interrupted cuts where toughness is required alongside wear resistance. Selecting the correct chipbreaker and matching the insert to a rigid holder will improve tool life and machining economy, often reducing total tooling costs per part. If process parameters vary significantly, consider slightly reduced depths of cut or increased feed to maintain edge security until full process parameters are validated.

FAQ

What clamping interface is required for this insert?
The CPMT09T308 T9225 insert is designed for ISO-style holders using a cylindrical hole with a single-sided countersink (40°–60°); secure clamping is achieved with the matching shim and screw arrangement.

Which materials is this insert optimised for?
This Tungaloy indexable insert is optimised for medium to heavy steel machining; the CVD-coated carbide and T9225 grade provide a compromise of wear resistance and toughness for such work.

How does the 0.8 mm corner radius affect cutting performance?
The 0.8 mm radius reduces local stress on the cutting edge, improving stability and resistance to chipping; it is beneficial where slightly heavier engagement or mild vibration is expected.

Is this insert suitable for interrupted cuts?
Yes — the T9225 grade is formulated for robust performance under changing engagement and light interrupted cuts; however, process stability and holder rigidity should be assessed before full-volume production.
