VBMT 160404 T9225 – Turning insert (VBMT160404-TSF) by Tungaloy

A VBMT 160404 T9225 ISO turning insert engineered for medium to heavy steel turning, offering a CVD-coated carbide grade and a TSF chipbreaker for interrupted and variable cutting conditions

• CVD-coated carbide T9225 for durable cutting
• Universal grade for medium to heavy steel
• Rhomboid 16 mm geometry, 5° relief angle
• 0.4 mm corner radius with TSF chipbreaker

Boosted throughput through a tougher grade and coating

The combination of the T9225 grade and a CVD-coated carbide substrate provides increased resistance to flank and crater wear under demanding steel-turning conditions. This insert is optimised for sustained cutting in the mid-to-heavy machining range, where variable engagement and occasional interruptions require additional toughness rather than only hardness. The result is more consistent tool life, fewer unplanned index changes and improved machine uptime, which directly translates into higher component throughput and predictable production cycles.

Consistent geometry for repeatable accuracy and surface quality

A defined rhomboid geometry with a 16 mm size, a 0.4 mm corner radius and a 5° relief angle ensures stable cutting behaviour and predictable chip flow. The modest corner radius balances edge strength with achievable surface finish, while the relief angle reduces rubbing on the flank, lowering heat build-up and improving dimensional repeatability. The insert’s central hole with a cylindrical bore and one-sided countersink (40°–60°) guarantees secure clamping, minimising micro-movements that can affect concentricity and final surface integrity.

Application-led design: optimised for steel turning and interrupted cuts

Equipped with the TSF chipbreaker, the insert is tailored to fragment and evacuate chips effectively when turning steel under varying engagement depths. A chipbreaker influences chip curl and thickness; the TSF profile is chosen to suit the grade’s toughness and the intended application, improving process reliability and reducing the risk of chip entanglement. Compatibility with ISO-format toolholders is determined by the insert’s form, relief angle, tolerance class, fastening and thickness — a standardised approach that simplifies holder selection and toolroom inventory management.

Economical machining with predictable change intervals

By combining a universal robust grade with a practical chipbreaking geometry, the insert offers an attractive balance between performance and cost-efficiency. Fewer premature index changes and more uniform wear patterns reduce handling time and tool cost per component. For production planners this means easier lifecycle forecasting and lower administrative overhead for reordering. The insert’s standard ISO designation and clear sizing support quick replenishment and straightforward logistics in any modern turning cell.

FAQ

What materials is this insert designed for?
The Tungaloy VBMT 160404 T9225 insert is designed primarily for medium to heavy steel machining and performs reliably under variable engagement and slightly interrupted cuts.

How does the TSF chipbreaker affect machining?
The TSF chipbreaker on the VBMT160404-TSF promotes controlled chip formation and evacuation, reducing the risk of chip entanglement and supporting stable cutting when turning steel.

Is the insert compatible with standard ISO toolholders?
Compatibility depends on the holder’s form, free angle, tolerance class, fastening, size and thickness; the VBMT160404-TSF follows ISO standards, which simplifies matching to appropriate external holders and boring bars.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius provides a compromise between edge strength and the achievable surface finish; it improves edge life while still allowing good surface quality for typical steel turning operations.

How is the insert secured in the holder?
The insert has a central cylindrical hole with a one-sided countersink (40°–60°) that ensures positive clamping and repeatable positioning when used with the correct clamping set and screw.
