SCMT 09T308 T9225 indexable insert for milling — Tungaloy

SCMT09T308-23 T9225 is an indexable milling insert designed for Tungaloy milling systems and engineered for medium to heavy steel milling operations.

• CVD-coated carbide grade T9225
• Suitable for medium to heavy steel milling
• Square 09 format with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Precise interface and system compatibility for predictable production

The indexable insert is designed to fit Tungaloy milling bodies where seat geometry and clamping match precisely, ensuring stable cutting engagement and repeatable tool life. The designation identifies the insert as a square 09 format with an included angle of 90°, making it suitable for a range of general-purpose milling tasks such as face, shoulder and slotting operations. The central cylindrical hole with an additional one-sided 40°–60° countersink supports secure clamping and simple orientation during assembly, reducing downtime and alignment checks on the machine.

Robust grade and coating for variable cutting conditions

Manufactured from CVD-coated carbide and specified as T9225, this insert offers a robust universal grade tailored to medium to heavy steel machining where interrupted cuts or variable engagement occur. The CVD coating improves wear resistance and heat management at elevated cutting temperatures, while the substrate combines toughness and hardness to resist chipping under fluctuating loads. As a result, the component delivers consistent performance across a wide range of feeds and speeds, supporting productive metal removal without frequent insert changes.

Geometry optimised for stability and surface quality

With a 0.8 mm corner radius and a 7° relief angle, the geometry balances edge strength and finish quality: the radius increases edge resilience at entry points, while the relief angle reduces rubbing and heat build-up. The 3.97 mm thickness contributes to mechanical stiffness and reduces vibration risk in moderate-depth milling tasks. Together these features help achieve an improved surface finish and longer stable cutting periods, which is particularly advantageous when switching between roughing and finishing passes in a single setup.

Application focus and process benefits in production environments

Specified for a broad range of milling tasks, the insert supports planing, shoulder work and contouring where tool families match the insert seating. The T9225 grade simplifies tooling decisions by covering many steels and mixed-production scenarios, reducing inventory complexity. Process reliability is enhanced through predictable wear behaviour and a secure clamping interface, which in turn lowers rework rates and contributes to more efficient cycle times on high-mix, low-volume shop floors and in serial production alike.

FAQ

Which materials can this insert machine effectively?
The SCMT09T308-23 T9225 indexable insert is formulated for medium to heavy steel applications; the CVD-coated carbide substrate combined with the T9225 grade offers a balance of toughness and wear resistance for variable steel cutting conditions.

Is the insert compatible with standard Tungaloy milling bodies?
Compatibility requires matching the clamping seat and geometry; the insert is intended for use in Tungaloy milling systems where the insert seat, geometry and cutter body are technically compatible.

How does the central hole and countersink affect clamping?
The cylindrical hole plus the 40°–60° countersink ensures secure mechanical engagement and correct orientation, which reduces assembly errors and enhances repeatability of cutting positions.

What advantages does the 0.8 mm corner radius provide?
A 0.8 mm radius increases edge strength at the corner, improving resistance to chipping during interrupted cuts and helping to maintain surface integrity during shoulder and roughing passes.

Can this insert be used for high-feed milling?
Application in high-feed milling depends on the associated cutter body and cutting parameters; the insert’s T9225 grade and geometry permit use in a variety of feed conditions when mounted in an appropriate high-feed-capable toolholder.
