VNMG120412E-ZM T9215 VNMG ISO turning insert — CVD-coated carbide, 1.2 mm radius, 35°

A VNMG120412E-ZM T9215 indexable turning insert engineered for efficient outer and inner turning of medium steels, combining a ZM chipbreaker with CVD-coated carbide for continuous to lightly interrupted cuts

• CVD-coated carbide grade T9215
• Optimised ZM chipbreaker for steel
• Rhombic VNMG form, 35° cutting angle
• 1.2 mm corner radius, 4.76 mm thickness

Achieve consistent productivity with a robust cutting grade

The combination of a CVD-coated surface and a wear-resistant carbide substrate in grade T9215 is designed to extend the service intervals while maintaining fracture toughness under typical production conditions. This results in fewer tool changes and reduced process downtime during continuous and lightly interrupted cuts. For workshops focusing on medium-steel turning, the investment in a high-performance grade delivers measurable gains in cycle-time stability and repeatability. The coating reduces flank and crater wear, while the substrate resists chipping, so component quality and tool life are both improved.

Predictable chip control and precise geometry for clean finishes

The ZM chipbreaker is optimised for steel machining and promotes controlled chip formation to improve machining reliability and surface quality. The insert’s rhombic geometry with a 35° main cutting angle and a 1.2 mm corner radius provides a balance between strength and form accuracy, enabling consistent profile control. A 0° relief angle and a plate thickness of 4.76 mm give secure seating in rigid holders, reducing vibration and improving surface finish. Compatibility with ISO-standard holders is determined by form, relief angle, tolerance class, fixation method, size and thickness — the insert is intended for use with an appropriate external holder or boring bar, plus backing pad and clamping set for secure assembly.

Durable performance and application guidance for production use

The tool grade pairs high wear resistance with sufficient toughness, making it suitable for a broad range of medium-steel applications where productivity and repeatable part quality are priorities. The ZM chipbreaker assists in preventing long, stringy chips and contributes to easier handling and safer machining. Selection of chipbreaker and grade should be matched to workpiece material, cutting parameters and assembly rigidity to exploit the insert’s full potential. For complex set-ups or alternating workpiece batches, refer to technical data and machining charts to adapt feeds and speeds; application-specific recommendations help to safeguard tool life and achieve the targeted surface integrity.
