SPMT090304 T9225 SPMT Turning Insert by Tungaloy — CVD‑coated carbide, 11° relief, 0.4 mm radius

The SPMT090304 T9225 Tungaloy turning insert is an ISO‑format, square indexable insert engineered for external and internal turning in steel; the universal T9225 grade provides toughness for varying entry conditions and lightly interrupted cuts.

• CVD‑coated carbide grade T9225
• Universal grade for medium to heavy steel
• ISO SPMT090304 format with 11° relief
• 0.4 mm corner radius, hole and countersink

Reliable cutting performance for mixed turning conditions

The combination of a CVD‑coated carbide body and the T9225 grade results in a wear‑resistant yet tough cutting edge designed for medium to heavy steel machining. This balance improves tool life under fluctuating engagement and mildly interrupted cuts, reducing the need for frequent indexing. The square plate format and specified 11° relief help maintain a stable cutting geometry in matched holders, which translates into predictable chip flow and consistent dimensional results on turned parts.

Practical system compatibility and setup benefits

The insert is built to ISO standards, ensuring fitment with compatible external holders, boring bars, shims and clamping kits when the form, relief angle, tolerance class, fastening, size and thickness match. The central cylindrical hole with one‑sided countersink (40°–60°) simplifies secure fastening and repeatable seating, while the plate thickness of 3.18 mm supports rigidity in assembly. Using a correctly matched clamping set and replacement screws helps to exploit the insert’s stability and maintain surface finish requirements with minimal set‑up time.

Efficiency gains and application guidance for shop floors

Selecting this universal grade insert supports productive turning workflows: the robust universal grade reduces the number of tool changes across a range of steel alloys, and the 0.4 mm corner radius offers a compromise between edge strength and profile detail. Where higher toughness is required, the grade tolerates slight interruptions without chipping, lowering scrap risk. For optimal results, pair the insert with a suitable ISO external holder and choose feeds and speeds that reflect material properties and machine rigidity to maximise tool life and process reliability.

FAQ

What materials is this insert suited for?
The Tungaloy SPMT090304 T9225 indexable insert is optimised for medium to heavy steel machining and tolerates varying engagement and light interruptions.

Can the insert be used for internal and external turning?
Yes; the ISO‑format plate and stable geometry make the insert suitable for both external and internal turning applications when paired with the appropriate holder and clamping components.

What fastening arrangement does the plate require?
The plate uses a central cylindrical hole with a one‑sided countersink (40°–60°) for secure fastening in compatible holders; proper shims and screws ensure repeatable seating.

How does the T9225 grade influence tool life?
The T9225 CVD‑coated carbide grade combines wear resistance with enhanced toughness, providing longer life under mixed cutting conditions and reducing edge failure risk in interrupted cuts.

Is the insert compliant with ISO dimensions?
Yes; the insert follows the ISO designation SPMT090304 and is intended for holders and systems that accept this format.
