SCMT120408 T9225 SCMT — Indexable milling insert for milling by Tungaloy

The SCMT120408 T9225 is a square indexable cutting insert for Tungaloy milling systems, developed for medium to heavy steel machining where intermittent cuts and variable engagement demand increased toughness.

• CVD-coated carbide grade T9225
• Robust universal grade for steel machining
• 0.8 mm corner radius for edge security
• Square form, 12 mm size, 90° geometry
• Central hole with 40°–60° countersink

Enhanced productivity for medium to heavy steel milling

The combination of a CVD-coated surface layer and a wear-resistant carbide substrate delivers an excellent balance between hardness and toughness. This results in longer tool life under changing cut conditions and lower overall tooling costs per component. The specified T9225 grade is optimised for stability in interrupted cuts, making it suitable for face, shoulder and heavy contour milling where consistent material removal rates are required. By selecting a grade tuned to mixed engagement conditions, machining cycles become more predictable and throughput improves without compromising surface quality.

Reliable integration into Tungaloy milling systems

Designed as part of a complete system, the insert requires matching cutter bodies, clamp screws and pads to ensure secure seating and repeatable positioning. The square form and 90° geometry allow straightforward indexation and multiple cutting edges per insert, increasing usable life per part. The central fastening hole with a 40°–60° countersink guarantees firm clamping and simple mounting on compatible tool holders. Where modularity and interchangeability matter, this geometry supports efficient tool changeovers and reduces setup time on the shop floor.

Edge security and cutting performance under load

A 0.8 mm corner radius provides a robust cutting edge that resists chipping during heavy engagement and interrupted cuts, while the single-sided chipbreaker manages swarf formation to maintain consistent chip flow. The insert’s 7° relief angle and 4.76 mm thickness contribute to stable cutting action and support under bending loads, reducing the risk of premature edge failure. For operations requiring a balance of surface finish and material removal, this configuration delivers durable performance with predictable wear patterns, simplifying tool life monitoring and process control.

Typical applications and handling guidance

The design suits a range of milling tasks: face milling, shoulder milling, slotting, high-feed operations and contour work, depending on the chosen cutter family. When selecting a tool body, ensure that seat geometry and clamp design match the insert specification to avoid misalignment. Spare inserts and clamping hardware should be kept compatible within the same system family to maintain process reliability.

FAQ

What materials is this insert intended for?
The SCMT120408 T9225 insert is intended primarily for medium to heavy steel machining and performs well under intermittent cutting conditions.

How does the T9225 grade affect tool life?
The T9225 CVD-coated grade increases resistance to abrasive wear while providing toughness for interrupted cuts; this combination typically extends usable tool life in variable engagement applications.

Is this insert compatible with other manufacturers’ tool bodies?
Compatibility requires identical seat geometry and clamping principles; the insert is designed for Tungaloy milling systems and requires matching cutter body geometry for safe, repeatable performance.

What benefits does the 0.8 mm corner radius provide?
A 0.8 mm corner radius offers enhanced edge strength and reduced chipping risk during heavy engagement, improving reliability in demanding milling operations.

Are there specific mounting recommendations?
Use the correct clamp screw and support pad specified for the matching tool family, and ensure the central countersunk hole aligns with the cutter body to achieve secure clamping.
