Description
Product Overview
The SHARS 1″ RH MWLN Turning Holder is engineered to meet the demanding requirements of modern machining environments. Featuring a precision‑machined 1″ shank, the holder provides a rigid connection between the machine spindle and the indexable insert, ensuring consistent tool geometry and repeatable results. The holder is compatible with WNMG style inserts, specifically sizes 331 and 332, allowing users to select the optimal cutting geometry for a wide range of materials, from stainless steel to hardened alloys. Constructed from high‑grade alloy steel, the holder offers excellent wear resistance and maintains dimensional stability even under prolonged high‑temperature cutting conditions. The Tri‑Lock indexing system delivers quick and secure insert changes, reducing downtime and improving overall productivity. With a total length of 6 inches and a -5° side cutting angle, the holder balances rigidity with accessibility, making it suitable for both manual and CNC turning applications.

Usage
Designed for medium to heavy turning operations, this holder excels in applications such as automotive component machining, aerospace part production, and general industrial manufacturing. The robust 1″ shank ensures that the holder can be mounted on standard CNC lathes and conventional turning centers without the need for additional adapters. Operators benefit from the straightforward WNMG insert replacement process, which requires only a simple twist to lock or unlock the insert, allowing for rapid tool changes during production runs. The holder’s geometry supports high feed rates and deep cuts while maintaining excellent chip control, making it ideal for roughing as well as finishing passes. Its durability and resistance to vibration enable consistent surface finish quality, even when machining difficult-to-cut materials like titanium or Inconel. The holder is also well‑suited for prototype work where flexibility and quick tool adjustments are essential.
