VNMG160404 T6215 — VNMG indexable turning insert for turning, CVD-coated cemented carbide, 0.4 mm radius — Tungaloy

The VNMG160404-SF T6215 is an ISO indexable turning insert intended for reliable external and internal turning, designed specifically for machining stainless steels in stable to lightly interrupted cuts.

• Indexable insert VNMG160404-SF by Tungaloy
• CVD-coated cemented carbide grade T6215
• 0.4 mm nose radius, rhombic 16 mm size
• Cylindrical hole, chipbreaker SF for controlled chips

Consistent wear resistance for stainless-steel turning

The CVD-coated carbide grade T6215 provides a wear-resistant cutting edge that keeps geometry stable over longer tool life, which translates into fewer insert changes and higher uptime. The CVD layer improves thermal and abrasive resistance compared with uncoated grades; this means more predictable flank wear when machining stainless steels, helping to maintain dimensional accuracy and part surface finish. For production environments where repeatability and process stability matter, the coated cutting substrate reduces the risk of unexpected tool failures and supports consistent cycle times.

ISO geometry and secure clamping for dependable repeatability

The insert follows the ISO VNMG form and is compatible with matching holders when form, clearance, tolerance class, fastening, size and thickness align. The rhombic shape and the cylindrical hole permit secure clamping with standard clamping kits and support plates, ensuring repeatable seating and torque transmission. Correct seating and clamp selection reduce micro-movements at the tool–workpiece interface, improving concentricity and surface quality. Where holder compatibility is unclear, users should verify form and thickness to confirm fit before use.

Geometry choices that balance edge strength and detail

A 0.4 mm nose radius offers a balance between edge robustness and the ability to produce fine details or tight tolerances; smaller radii reduce cutting forces on interrupted cuts, while still providing adequate edge strength for many finishing and light-roughing passes. The insert’s 0° clearance angle requires appropriate toolholder geometry to achieve the intended cutting edge orientation; correct matching prevents rubbing and preserves the intended contact angle. The SF chipbreaker is matched to the grade for controlled chip formation in the targeted stainless-steel applications, reducing the likelihood of long, stringy chips and the need for secondary chip control measures.

Practical selection and workshop benefits

Choosing this insert for turning tasks reduces process variability through a proven combination of grade and geometry; the result is fewer rejects and more predictable tool life. The ISO standardisation simplifies inventory: a familiar insert form and recognised dimensions make it easier to stock holders and spare inserts across multiple machines. For shops aiming to optimise production, the combination of a robust coating, standardised geometry and a clear chipbreaking concept provides a pragmatic route to improved throughput and lower per-part tooling cost.

FAQ

What material is the VNMG160404-SF T6215 intended for?
The VNMG160404-SF T6215 is formulated for machining stainless steels, offering enhanced wear resistance for stable to slightly interrupted turning operations.

How does the CVD coating affect performance?
A CVD-coated cemented carbide base enhances thermal and abrasive resistance, so inserts in grade T6215 generally deliver longer life and more consistent wear when turning stainless-steel alloys.

What does the SF chipbreaker do?
The SF chipbreaker promotes controlled chip formation for the intended cutting conditions, reducing the risk of long, stringy chips and improving process safety and part finish.

Which holders are compatible with this insert?
Compatibility depends on matching the VNMG form, clearance angle, tolerance class, fastening method, size (16 mm) and thickness (4.76 mm); holders designed for ISO VNMG inserts with a cylindrical-hole clamping system are commonly used.

Is the 0.4 mm nose radius suitable for finishing passes?
Yes—0.4 mm offers a compromise between edge strength and the ability to achieve fine surface finishes, making it suitable for many light-roughing and finishing applications.
