VBMT 160402 T9225 — ISO rhombic turning insert for medium‑heavy steel, CVD‑coated carbide

VBMT160402-TM T9225 is an ISO‑standard rhombic insert made for external and internal turning in steel; the geometry and grade suit interrupted cuts and varying engagement conditions

• CVD-coated carbide grade T9225
• TM chipbreaker for medium-heavy steel
• Rhombic ISO insert, 35° cutting angle
• 0.2 mm corner radius, 4.76 mm thickness

Predictable performance in medium‑to‑heavy steel machining

The CVD‑coated carbide grade T9225 is formulated for robust, universal performance when turning steel under changing engagement conditions. Combined with the TM chipbreaker, the insert offers controlled chip formation and enhanced edge stability, which reduces unexpected downtime and extends tool life. For shops running mixed batches or occasional interrupted cuts, this combination provides a practical balance of toughness and wear resistance that keeps cycle times consistent and regrinding intervals predictable.

Clear system compatibility and mounting guidance

As an ISO‑standard rhombic insert, VBMT160402-TM T9225 integrates into a standard turning system consisting of the insert, a matching external holder or boring bar, and the required shim/clamping set plus replacement screws. Compatibility depends on form, 5° relief angle, tolerance class, mounting method, size and thickness; the insert features a cylindrical hole with a single‑sided countersink (40°–60°) to suit common clamping designs. Specifying the correct holder geometry and tolerance class ensures repeatable seating and concentricity, which is critical for accurate runout and surface finish.

Practical edge geometry for reliable finishing and roughing

The insert’s 35° cutting angle and 0.2 mm corner radius are chosen to deliver a compromise between strength and edge definition: the radius supports heavier cuts and interrupted conditions, while the included angle promotes stable engagement and acceptable surface integrity. At 4.76 mm thickness, the insert provides a rigid cutting edge that resists chipping under variable loads. When paired with an appropriate feed and speed strategy, this geometry yields consistent side force distribution and helps to maintain dimensional accuracy across production runs.

Ease of selection and application advice

Choosing the correct chipbreaker and grade is essential: for heavy interrupted cuts, favour lower cutting speeds and the TM chipbreaker with T9225 to benefit from enhanced toughness; for continuous finishing, optimise feeds to exploit the insert’s wear resistance. The ISO designation and available dimensional data make cross‑referencing with holders straightforward, enabling faster changeovers and fewer trial passes during setup. For any uncertainty on holder fitment or cutting data, technical consultation is available to adapt the insert to a specific machine or workpiece.

FAQ

What materials is this insert suitable for? The VBMT160402-TM T9225 insert with CVD‑coated carbide is designed primarily for steel machining and performs well in medium‑to‑heavy turning tasks.

Is the insert compatible with standard ISO holders? Yes, the VBMT160402-TM follows ISO geometry; compatibility depends on holder form, relief angle, tolerance class, mounting and plate thickness.

What does the TM chipbreaker provide? The TM chipbreaker on this insert improves chip control and edge stability, which is particularly beneficial during interrupted cuts or variable engagement.

Which cutting parameters are recommended for roughing and finishing? For roughing, lower speed with higher feed and the T9225 grade increases toughness and resistance to chipping; for finishing, moderate feeds exploit the grade’s wear resistance for better surface quality.

How does the 0.2 mm corner radius affect performance? A 0.2 mm corner radius offers a balance between edge strength and surface finish, supporting heavier cuts while still allowing reasonable final surface integrity.
