SPMT090304 T9225 indexable turning insert, Tungaloy

The SPMT090304 T9225 is an ISO‑standard indexable insert for external and internal turning, engineered as a robust universal grade for medium to heavy steel machining where interrupted cuts or varying engagement demand higher toughness.

• CVD-coated carbide grade T9225
• ISO SPMT 090304 geometry for turning
• 11° clearance; 0.4 mm corner radius
• Square 09, 3.18 mm thick; with central hole

Consistent performance in demanding steel turning

The insert delivers stable cutting under changing conditions thanks to its CVD coating on a wear‑resistant carbide substrate. This combination increases heat tolerance and reduces flank wear during extended cuts, which translates into longer tool life and fewer changeovers. Designed for medium to heavy turning, the geometry supports larger depth of cut while the grade offers sufficient toughness for interrupted or semi‑stable cuts, reducing the risk of chip‑induced edge chipping and improving process reliability.

Seamless integration into ISO turning systems

Compatibility with toolholders is defined by form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s ISO SPMT 090304 designation ensures straightforward selection of matching holders and boring bars. The square 09 format and 3.18 mm thickness provide a compact, rigid seating in standard clamping systems, while the centrally drilled configuration with a countersink facilitates secure fastening and repeatable positioning in the pocket.

Coating and substrate combination that extends productivity

The CVD coating supports higher cutting temperatures and helps control built‑up edge formation when machining steel, thereby maintaining a consistent cutting edge over longer cycles. As a universal grade, the material blend favours a broad workpiece range and offers predictable wear behaviour; this reduces the need for frequent grade swaps and simplifies inventory management in mixed‑material production environments.

Process guidance: choose the right chipbreaker and setup

Selecting the one‑sided chipbreaker that matches workpiece material, machining type and machine stability is key to achieving secure chip control and surface finish. For external or internal turning where stability might vary, pair the grade with a more robust chipbreaker and conservative feeds until the process is validated; once stable, feeds can be increased to exploit the insert’s durability and maximise productivity. The square shape also allows multiple indexing positions, supporting economical use and quick edge changes.

FAQ

Is this insert compatible with standard SPMT holders?
The SPMT090304 T9225 is ISO‑designated and compatibility depends on holder form, clearance, tolerance, fastening and thickness; select an SPMT pocket and clamp rated for 09 size and 3.18 mm plate thickness.

Which materials is the grade intended for?
The T9225 grade is a robust universal choice optimised for steel machining and is particularly suitable for medium to heavy turning where occasional interruption or varying engagement occurs.

What is the purpose of the central hole and countersink?
The centrally drilled feature with a one‑sided countersink ensures secure fastening, repeatable seating in the pocket and simplified index changes when using standard clamping screws.

How should the chipbreaker be matched to the application?
Chipbreaker selection must reflect workpiece material, cut stability and type of turning; the one‑sided chipbreaker on this insert offers controlled chip formation for general turning, but more aggressive or smoother chipbreakers may be chosen depending on finish and chip control requirements.

How many cutting edges are available before indexing?
Edge count depends on insert orientation and how many sides are usable in the chosen pocket; the square form allows multiple index positions for extended service life and economical edge utilisation.
