VNMG 160412 T6215 rhombic turning insert — CVD-coated carbide for stainless steels, 1.2 mm corner radius (Tungaloy)

VNMG 160412 T6215 is a rhombic ISO insert designed for precision turning of stainless steels under stable to mildly interrupted conditions

• CVD-coated carbide for wear resistance
• Optimised for turning rostfreier Stahl
• Rhombic VNMG geometry, 35° cutting angle
• Cylindrical hole for secure mounting

Long tool life and consistent surface quality through advanced coating

The T6215 grade combines a CVD-coated carbide substrate with a microstructure tuned to resist abrasive wear during the machining of stainless steels. This results in a longer tool life and more predictable replacement intervals, which supports continuous production and reduces unscheduled downtime. The coating improves resistance to built-up edge formation on stainless alloys, so the insert maintains a stable cutting edge under prolonged contact and moderate feed rates. For applications that demand reproducible finishes, the enhanced wear performance translates directly into lower rework rates and more efficient use of machine time.

ISO compatibility and mechanical stability simplify setup and changeover

The insert follows ISO dimensions for rhombic turning inserts (VNMG 160412), ensuring compatibility provided the holder matches form, relief, tolerance class, fixation and thickness. Key dimensional data — size 16, thickness 4.76 mm, corner radius 1.2 mm and a 35° main cutting angle — make it straightforward to select a suitable external holder or boring bar. The cylindrical centre hole ensures reliable clamping and repeatable positioning, reducing indexing time when rotating or replacing the insert. Clear, standardised geometry helps workshops maintain process stability and simplifies inventory management across holder families.

Application-focused performance for stable and lightly interrupted turning

Engineered for general turning tasks, the insert’s double-sided chipbreaker design offers two usable cutting edges, improving cost-efficiency per edge. The moderate corner radius of 1.2 mm balances edge strength and surface finish, making the insert suitable for external and internal turning where both dimensional control and edge robustness are required. The grade performs best in stable cutting conditions or slight interruptions; selecting the appropriate chipbreaker and cutting data according to workpiece rigidity and machining strategy will yield optimal results. If holder selection or cutting-parameter tuning is necessary, technical guidance supports the transfer of the insert’s capabilities into measurable productivity gains.

FAQ

What materials is this insert suited for?
The VNMG 160412 T6215 insert is formulated for machining stainless steels and performs best under stable to slightly interrupted turning conditions.

How many usable cutting edges does the insert provide?
Thanks to the double-sided chipbreaker design, the insert offers multiple indexing positions to maximise edge utilisation before replacement.

What dimensions must a compatible holder support?
A holder must match the VNMG 160412 geometry, accommodate a 16 size inscribed circle and a 4.76 mm plate thickness, and provide secure clamping for the cylindrical centre hole.

Is the T6215 grade suitable for interrupted cuts?
The T6215 grade is wear-resistant and tolerates slight interruptions; for heavy interruption or unstable setups, a tougher geometry or different grade should be considered.

How does the CVD coating benefit stainless steel turning?
The CVD coating on the carbide substrate improves wear resistance and reduces built-up edge tendencies when machining stainless steels, enhancing surface finish consistency.
