VCMT 160408 T9225 – VCMT160408-24 T9225 ISO turning insert (Tungaloy)

VCMT160408-24 T9225 is an ISO rhombic turning insert designed for medium-to-heavy steel machining and applications with intermittent cuts

• CVD-coated carbide for extended tool life
• Robust universal grade T9225 for steel turning
• ISO rhombic 160408 format for easy replacement
• 0.8 mm nose radius and 7° relief angle

Consistent performance under varying cut conditions

The VCMT160408-24 T9225 indexable insert is engineered as a robust universal grade for medium-to-heavy steel turning, offering a balance of toughness and wear resistance suited to interrupted cuts and changing engagement. The combination of a CVD coating and a carbide substrate provides improved thermal stability and abrasion resistance, which reduces flank wear and extends service intervals. For production environments, this translates into fewer insert changes, steadier cycle times and predictable tool-life behaviour, supporting reliable throughput and lower total machining costs.

ISO compatibility that reduces downtime and simplifies inventory

Being an ISO-formatted rhombic insert (VCMT 160408), the design ensures interchangeability with common toolholders when form, relief angle, tolerance class, clamping and thickness match. The 16 mm size, 4.76 mm thickness and the cylindrical hole with single-sided countersink (40°–60°) support secure clamping and straightforward replacement. Standardised geometry helps minimise changeover time and reduces the variety of spare parts required in the tooling cabinet, which is particularly valuable for job shops and production lines aiming for efficient logistics and quick setup.

Coating and substrate explained for predictable durability

The CVD coating applied to this carbide insert enhances resistance to abrasive wear and improves performance at elevated cutting temperatures. Unlike some surface-only treatments, CVD layers bond metallurgically with the carbide, offering a durable barrier that preserves the cutting edge under sustained loads. The T9225 grade is specified as a universal, tougher option: it favours stability over the absolute maximum hardness, making it suitable where edge security during slight interruptions or variable feeds is critical. The result is more consistent surface finish and longer intervention intervals in mixed production runs.

Practical selection: nose radius, chipbreaker and application fit

The 0.8 mm nose radius contributes to improved part finish and stronger edge geometry compared with finer radii, while the 7° relief angle helps to balance cutting forces and reduce rubbing on the flank. The fitted chipbreaker 24 is intended to control chip formation in typical steel turning operations; matching chipbreaker style and grade to the workpiece material and machine rigidity is essential for optimal results. For unstable set-ups or heavily interrupted cuts, the chosen robust grade and chip control help avoid premature chipping. When in doubt about the combined choice of grade, chipbreaker and holder, consult a tooling specialist to tune parameters to the specific machine and workpiece.

FAQ

What materials is this insert intended for?
The VCMT160408-24 T9225 insert (Tungaloy, ISO turning insert, SKU 6781097-Tungaloy) is primarily specified for steel machining, particularly in medium-to-heavy operations where toughness and stable chip control are required.

How does the T9225 grade differ from harder grades?
T9225 is a robust universal grade with a focus on toughness and reliable edge security; it sacrifices some maximum wear resistance in favour of better performance under interrupted cuts and variable engagement compared with harder, more brittle grades.

Is this ISO insert compatible with standard toolholders?
Yes; the VCMT 160408 geometry conforms to ISO rhombic standards. Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness—matching these parameters ensures correct seating and secure clamping.

What advantage does the 0.8 mm nose radius offer?
A 0.8 mm radius gives a stronger cutting edge and improved surface finish versus finer radii; it also distributes cutting forces over a slightly larger area, which is beneficial for roughing and semi-finishing in steel.

What does chipbreaker 24 indicate?
The chipbreaker designation denotes the chip control geometry tailored to the T9225 grade and typical steel applications; it is designed to produce manageable chips and stable cutting under the intended feed and depth conditions.
