MVWNR/L Internal Boring Bar | Turning Tool Holder for VNMG16 Inserts

The MVWNR/L internal boring bar is a precision-engineered CNC internal turning tool holder designed to hold VNMG16 carbide inserts. Featuring a 93° approach angle and optimized insert positioning, this boring bar delivers outstanding rigidity, chip control, and performance in deep-hole and internal machining applications.

High-Performance Boring Bar for VNMG16 Inserts

Designed for internal turning, facing, and profiling operations, the MVWNR (right-hand) and MVWNL (left-hand) boring bars ensure superior access to tight bores and complex internal features. The robust steel body and secure insert clamping system provide excellent vibration damping and tool stability at high speeds.

Key Features

• Accepts standard VNMG16 inserts (35° rhombic geometry)
• MVWNR for right-hand cutting / MVWNL for left-hand cutting
• Ideal for internal turning, boring, facing, and profiling
• Anti-vibration design ensures stable and precise machining
• Suitable for stainless steel, alloy steel, cast iron, and aluminum

Applications

MVWNR/L internal turning holders are widely used in CNC lathes, Swiss-type machines, and turning centers across aerospace, automotive, and mold-making industries. They are especially valuable in applications requiring clean surface finish and high dimensional accuracy in internal geometries.
