SCMT09T304 T9225 — CVD-coated carbide ISO turning insert, 0.4 mm radius (Tungaloy)

The SCMT09T304 T9225 is a square ISO indexable insert engineered for external and internal turning operations, providing a robust combination of wear resistance and toughness for varying engagement conditions.

• CVD-coated carbide grade T9225
• Square geometry with 90° included angle
• 0.4 mm nose radius for versatile finishing
• Cylindrical hole with single-sided countersink

Reliable cutting performance for medium to heavy steel turning

The combination of a CVD-coated surface on a tough carbide substrate (grade T9225) is designed to balance wear resistance and edge strength, making the insert well suited to interrupted cuts and variable engagement. The moderate nose radius of 0.4 mm supports consistent surface finish without compromising chip control, while the coating reduces built-up edge and increases tool life under standard turning feeds and speeds. This results in predictable machining behaviour and reduced downtime for insert changes.

Secure seating and straightforward holder compatibility

As an ISO-compliant turning insert, compatibility with the toolholder is governed by the insert form, relief angle, tolerance class, clamping method, size and thickness. The square shape with a 90° included angle offers four usable cutting edges per insert, while the 7° relief angle and 3.97 mm plate thickness support reliable clamping and repeatable positioning in standard external holders and boring bars. The cylindrical hole with a single-sided countersink (40°–60°) ensures secure fixation with common screw systems and a stable cutting geometry for consistent results.

Practical guidance for selection and application

The single-sided chipbreaker and the universal nature of the grade make this insert suitable for a range of turning tasks. Typical uses include external finishing and medium-depth roughing as well as internal turning where stability permits. Selection of the matching chipbreaker and grade should consider workpiece material, machine rigidity and cutting strategy: when facing interrupted cuts or variable engagement, the T9225 grade offers added toughness; for high-speed, uninterrupted finishing, consider a finer edge preparation or a different grade optimised for speed. Proper clamping, correct seating in the holder and adherence to recommended cutting parameters will extend insert life and improve surface quality.

FAQ

What materials is this insert intended for?
The SCMT09T304 T9225 insert is intended primarily for steel machining; the T9225 grade is a robust universal choice for medium-to-heavy steel turning and variable engagement conditions.

How many cutting edges are available per insert?
The square design provides four usable cutting edges; the insert can be indexed to present a fresh edge once one becomes worn.

What does the 0.4 mm radius affect in turning?
A 0.4 mm nose radius balances finish and strength: it improves surface quality compared with a very sharp tip while maintaining sufficient edge strength for typical finishing and medium turning operations.

Is the insert compatible with standard ISO holders?
Yes, the SCMT09T304 follows ISO seat and form conventions; compatibility depends on matching holder shape, relief angle, tolerance class, clamping and plate thickness.
