SPMR 120304 T9225 turning insert (SPMR series) by Tungaloy

SPMR 120304 T9225 is a square ISO turning insert for external and internal turning, designed for stable cutting performance in mixed or interrupted cuts.

• CVD-coated carbide for robust performance
• ISO SPMR form for standard holder compatibility
• Square insert, 12 mm size and 3.18 mm thickness
• Single-sided chipbreaker for stable chip control

Increased throughput for medium–heavy steel turning

The CVD-coated carbide in grade T9225 is formulated for robust universal performance, particularly where variable engagement or light interruptions occur. The coating enhances wear resistance and thermal stability, which leads to longer tool life and more consistent cycle times. For production environments requiring repeatable results, this combination reduces unscheduled tool changes and supports steady spindle utilisation. The result is improved process economy and lower per-part cutting costs without sacrificing surface quality.

Straightforward integration with ISO tooling systems

The square ISO SPMR geometry and standardised dimensions ensure straightforward compatibility with common external holders and boring bars. Key dimensions—12 mm inscribed circle, 3.18 mm thickness and an 11° relief angle—allow predictable seating and clamping. Compatibility is governed by insert form, relief angle, tolerance class, and mounting type; matching these parameters avoids assembly errors and ensures the insert seats correctly for stable cutting. This simplifies tooling audits and reduces setup time in mixed-machine shops.

Stable chip control and practical selection guidance

A single-sided chipbreaker provides reliable chip formation for many steel grades and turning operations, improving surface finish and evacuation in both cylindrical and boreside cuts. The modest 0.4 mm corner radius balances strength and profile accuracy, making the insert suitable for general profiling and shoulder work. For system setup, pair the insert with the appropriate external holder or boring bar, a compatible clamp or shim, and correct clamping screws to maintain repeatable clamping forces. Where uncertain cutting conditions arise, select the T9225 grade for enhanced toughness under changing feeds and interrupted cuts.
