About the product
The MTQNR Indexable CNC Lathe Turning Tool Holder is engineered for high-precision external turning applications. It features a robust multi-clamp design
with a 105° approach angle, compatible with a wide range of negative triangle inserts like TNMG160404, TNMG160408, and TNMG160412. This tool holder
is known for its exceptional stability and precision, with a secure locking system that minimizes vibrations and ensures optimal surface quality. Made from
high-grade 40Cr material, it offers wear resistance and durability for heavy-duty machining. The MTQNR tool holder is suitable for various materials, including
stainless steel and hard materials, and is recognized for enhancing productivity and reducing tool changeover times

The MTQNR Indexable CNC Lathe turning Tool Holder is forged from high-grade 40Cr alloy steel, a material celebrated for its optimal balance of strength and machinability.
Through precise heat treatment, it achieves a hardness of HRC 45-50, ensuring excellent wear resistance while retaining sufficient toughness to withstand the lateral forces
of external turning. This robust material foundation makes it ideal for prolonged exposure to heavy-duty machining environments.
High-Precision Clamping: The multi-clamp design, paired with a secure locking system, eliminates play between the tool holder and inserts (such as TNMG160404, TNMG160408, and TNMG160412). This tight fit minimizes vibration during high-speed rotation, directly contributing to superior surface finishes (Ra ≤ 1.6μm) on machined workpieces.
Optimized Cutting Geometry: The 105° approach angle is engineered to reduce cutting forces and chip load, making it efficient for both roughing and finishing operations. This angle also enhances tool access in hard-to-reach areas, such as stepped diameters or shoulder turning.
Quick Change Compatibility: Designed for rapid insert replacement, the tool holder reduces changeover times by up to 40% compared to traditional setups. This feature is critical for high-volume production lines where downtime directly impacts productivity.
Automotive: Machining shafts, hubs, and brake rotors from stainless steel, carbon steel, and cast iron.
Aerospace: Finishing precision components (e.g., landing gear parts) made from heat-resistant alloys.
General Engineering: Producing cylindrical surfaces, tapers, and grooves on industrial machinery parts with tight tolerances (±0.01mm).
Horizontal CNC lathes (e.g., Mazak QT series, Haas TL-25) with turret tool changers.
Slant-bed CNC lathes, which offer enhanced rigidity for heavy-duty turning.
Multi-axis turning centers, supporting complex operations like live tooling and sub-spindle machining.

Slant-bed CNC lathes, which offer enhanced rigidity for heavy-duty turning.
Multi-axis turning centers, supporting complex operations like live tooling and sub-spindle machining.
With proper maintenance (regular cleaning of clamping surfaces and lubrication of adjustment screws), the MTQNR tool holder delivers a long service life.
The 40Cr steel construction, combined with its vibration-resistant design, allows it to endure 8,000+ hours of continuous operation. Inserts paired with this
holder also benefit from reduced wear—lasting 20-30% longer than in less stable holders—thanks to minimized chipping and even pressure distribution during cuts.
