5/8″ Left Cutting Lathe Carbide Indexable Tool Holder Set MTJNL1616H16

Description

Product Overview

The 3‑piece 5/8″ left‑cutting CNC lathe tool holder set is engineered for high‑performance turning applications where precision and durability are paramount. Each holder—MTJNL1616H16, MWLNL1616H08, and MCLNL1616H12—features a black oxidized finish that not only resists corrosion but also provides a smooth, low‑friction interface with the spindle. The shank diameter of 5/8″ (16 mm) and overall length of 100 mm ensure a rigid connection, while the HRC 48 hardness rating guarantees resistance to wear even under demanding cutting conditions.

Accompanying the holders are three indexable carbide inserts: wnmg431, cnmg431, and tnmg331. These inserts are crafted from high‑grade tungsten‑nickel‑molybdenum carbide, delivering exceptional toughness and edge retention. The indexable design allows rapid tool changes, minimizing downtime and maximizing productivity on the shop floor. Additionally, the set includes three precision‑ground shims and a set of wrenches, providing a complete solution straight out of the box.

Manufactured by XUZHOU BAIYI Metal Technology Co., Ltd., a reputable supplier known for rigorous quality control, this tool holder set meets ISO standards for dimensional accuracy and surface integrity. The product dimensions of 1.6 × 1.6 × 0.04 inches and a weight of 1.61 lb make it easy to handle while maintaining the robustness required for heavy‑duty machining. Since its launch on October 26 2017, the set has earned a solid reputation, reflected in a 4.5‑star rating from over 200 verified customers.

Usage

This tool holder set is ideally suited for a wide range of CNC turning operations, including aerospace component fabrication, automotive part machining, and precision instrument manufacturing. The left‑cutting geometry is optimized for applications where the workpiece rotates clockwise, delivering smooth chip flow and reduced vibration. Whether you are producing small‑diameter shafts, complex contours, or high‑speed finish passes, the combination of hardened holders and premium carbide inserts ensures consistent surface finish and dimensional accuracy.

Professional machinists and hobbyists alike will appreciate the ease of setup. The included shims allow fine adjustment of tool offset, while the ergonomic wrenches simplify insert changes without the need for additional tooling. The set’s versatility also extends to compatibility with a broad spectrum of CNC lathe models, making it a flexible addition to any machining center inventory.
