SHARS 3/4″ RH TCBN T-Type TRI-Lock Turning Holder 4-1/2″ Shank

Description

Product Overview

The SHARS 3/4 RH TCBN T-Type TRI-Lock Turning Holder is engineered for high‑performance machining environments where precision, durability, and rapid tool changes are essential. Constructed from hardened steel, the holder features a 4‑1/2″ shank that provides a solid, vibration‑dampened interface between the machine spindle and the cutting insert. Its TCBN (titanium carbonitride) coating delivers exceptional wear resistance, extending tool life even under aggressive cutting conditions. The TRI‑Lock clamping system utilizes three equally spaced locking points, guaranteeing uniform pressure distribution across the insert and eliminating the risk of misalignment. This design supports CNMG inserts in sizes 431, 432, and 433, making it a versatile solution for a wide range of turning applications, from aerospace component finishing to automotive part production. The holder’s right‑hand configuration aligns with standard CNC turning setups, ensuring seamless integration into existing tool libraries.

Usage

Designed for both CNC and manual turning centers, the SHARS TRI‑Lock holder excels in environments where repeatable accuracy and quick changeover are critical. Machinists can install or replace inserts in seconds, reducing non‑productive time and increasing overall shop throughput. The holder is ideal for high‑speed turning of hardened steels, stainless alloys, and exotic materials such as titanium and Inconel, where the TCBN coating provides the necessary thermal stability. Its robust construction also makes it suitable for heavy‑cutting operations, including roughing passes and finish machining. Whether used in aerospace component manufacturing, automotive engine part production, or general industrial machining, the holder delivers consistent rigidity, minimizing deflection and ensuring tight tolerances across the entire machining cycle.
