VNMG 160408 T5105 VNMG160408-CF – ISO rhombic turning insert for cast iron by Tungaloy

A VNMG160408-CF T5105 ISO rhombic insert engineered for high-speed external and internal turning of cast iron under stable conditions

• CVD-coated carbide for high-speed machining
• Optimised chipbreaker CF for stable chips
• Rhombic VNMG shape, 35° cutting geometry
• 0.8 mm corner radius for accurate profiles

Consistent wear resistance for high-speed cast iron turning

The CVD-coated T5105 grade provides enhanced wear resistance specifically for the demands of high-speed machining of cast iron, allowing extended intervals between tool changes and fewer unscheduled stops. The coating and substrate combination is designed to tolerate the abrasive nature of grey and nodular cast iron while maintaining a stable cutting edge. This translates into improved machine uptime and a predictable tool-change cycle, which supports more efficient production planning and lower overall machining costs.

Geometry that stabilises chips and improves surface finish

The rhombic VNMG form combined with the CF chipbreaker produces controlled chip formation and evacuation, reducing the risk of re-cutting and workpiece damage. The 35° approach angle reduces cutting forces on the tool and workpiece, while the 0.8 mm corner radius contributes to repeatable profile accuracy and improved surface quality. The specified 0° clearance angle suits neutral cutting positions and should be considered when selecting the mating holder to ensure the intended contact geometry and cutting performance.

ISO compatibility for straightforward tool system integration

As an ISO-designated turning insert, compatibility with holders is governed by the insert shape, clearance angle, tolerance class, fixing method, size and thickness. The plate features a central cylindrical hole for positive locating and screw fixation, and the complete system typically comprises the ISO insert, an appropriate external holder or boring bar, a shim/clamping set and replacement screws. Keeping these components matched avoids play at the cutting edge and secures stable cutting conditions across batch runs.

Production benefits and selection guidance

Using a grade optimised for cast iron together with an appropriate chipbreaker reduces scrap rates and delivers consistent part geometry—advantages that directly support cost-efficiency and process reliability. For best results, choose the chipbreaker and grade to match material, machining stability and feed conditions; under unstable setups a different chip control strategy may be necessary. If clarification is required on holder compatibility or grade selection, technical advice is available to align the insert with the machining task and maximise productivity.
