CCMT 09T312 T9225 turning insert — CVD-coated carbide, 1.2 mm corner radius (Tungaloy)

CCMT09T312 T9225 is a CVD-coated carbide indexable insert designed for medium-to-heavy turning of steel, offering a balance of toughness and wear resistance for interrupted cuts and varying engagement conditions.

• CVD-coated carbide for high wear resistance
• Robust grade for medium to heavy steel
• 1.2 mm corner radius for edge strength
• Rhombic ISO CCMT09 form, with hole

Maximised productivity for steel turning

The CVD-bonded carbide composition of this grade delivers a controlled mix of hardness and toughness: T9225 is specified for medium-to-heavy steel turning, where variable cutting conditions and light interruptions demand greater edge resilience. The combination of coating and grade reduces flank wear and extends tool life under higher contact loads, which translates into fewer index changes and increased uptime. Productivity gains arise from steady cutting performance and a lower incidence of catastrophic edge failure, making the solution well suited for serial production and mixed-batch machining where consistent cycle times matter.

Secure cutting edge and controlled chip flow

Chip control is managed by the one-sided chipbreaker geometry and the insert’s rhombic form; this directs chips away from the cutting zone and supports stable cutting forces. The 1.2 mm corner radius reinforces the edge against shock, while the 7° clearance angle reduces rubbing on the flank face to preserve surface finish. The insert’s 80° included angle provides favourable strength for turning operations that require robust support at the cutting edge. Together, these features help maintain dimensional stability and surface quality with fewer tool changes, and they simplify explanations of technical trade-offs for teams less familiar with indexable insert technology.

Simple compatibility and practical mounting

The CCMT format follows ISO sizing conventions, here supplied as CCMT09T312, with a plate thickness of 3.97 mm and a rhombic shape that suits common clamping systems. Compatibility with a given holder is determined by the holder form, free/clearance angle, tolerance class, fastening method, size and thickness; the included cylindrical hole with one-sided countersink (40°–60°) ensures secure seating and straightforward replacement. Typical system components include the ISO insert, a matching external holder or boring bar, a locating shim or clamp set and replacement screws — a standardised approach that reduces stocking complexity and shortens machine downtime.

FAQ

What materials is this insert suitable for?
The CCMT09T312 T9225 insert is optimised for steel machining and performs well in medium-to-heavy cutting situations where toughness and wear resistance are required.

How does the T9225 grade behave with interrupted cuts?
Tungaloy’s T9225 grade offers increased toughness and stable chip formation, making it resilient under light interruptions common in turning operations.

What should be checked for holder compatibility?
Confirm holder form, free/clearance angle, tolerance class, fastening style, size and thickness; these determine mechanical fit and safe clamping of the CCMT09T312 insert.

Does the insert require special clamping hardware?
The rhombic CCMT form with a cylindrical hole and countersink fits standard ISO clamping systems; matching shims and screws are recommended to ensure repeatable seating.
