TCMT 16T304 T9225 indexable insert for turning — Tungaloy

A TCMT16T304 T9225 indexable insert engineered for ISO-standard external and internal turning, offering a balanced combination of toughness and wear resistance for varying cut conditions.

• CVD-coated carbide for high wear resistance
• Universal T9225 grade for medium to heavy steel
• 60° triangular shape with 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Dependable performance under varying cut conditions

The combination of a CVD coating and a robust carbide substrate delivers consistent edge life where interrupted cuts or variable engagement occur. The T9225 grade is formulated for higher toughness than typical finishing grades, which reduces edge chipping during semi-roughing and heavier passes. This results in fewer insert changes and improved machine uptime. For manufacturers requiring steady productivity, the design reduces unexpected tool failures and supports predictable process planning.

Secure clamping and geometric advantages for stable turning

A 60° triangular geometry provides three cutting corners per insert, increasing economy and flexibility. The insert’s 0.4 mm corner radius smooths cutting forces and enhances component surface integrity during medium to heavy cuts, while the 7° clearance angle helps avoid rubbing on the flank face. The cylindrical hole with a single-side countersink (40°–60°) ensures precise seating in compatible holders, so clamping rigidity is maintained and vibration is reduced — an important factor for repeatable dimensions and tool life.

Practical handling, compatibility and selection guidance

ISO standardisation of the insert format simplifies tool procurement and holder selection: compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness. The 3.97 mm plate thickness and triangular form suit a wide range of external and internal turning holders. Given the single-sided chipbreaker, choose the chipbreaker and grade aligned with material and operation stability for optimal chip control. For shops new to the grade, trial a single geometry under representative conditions to confirm cutting parameters and tool life expectations.

FAQ

What materials is this insert suited for?
The TCMT16T304 T9225 insert is designed primarily for steel machining and performs well in medium to heavy steel turning applications thanks to its tougher CVD-coated carbide grade.

How many cutting edges are available per insert?
The triangular geometry provides three usable cutting corners; rotation between corners extends tool life and reduces cost per part.

What is the purpose of the 0.4 mm corner radius?
A 0.4 mm corner radius moderates cutting forces and improves surface finish during heavier cuts while helping to avoid premature edge chipping in interrupted cuts.

Is the insert compatible with all ISO holders?
The insert follows ISO form and dimensions, but compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness; check holder specifications before mounting.

Does the CVD coating suit high-speed finishing?
The CVD-coated T9225 grade prioritises toughness for semi-rough to heavy cuts; for high-speed finishing, consider a finer, smoother grade optimised for finish operations.
