Description
Product Overview
The SHARS 3/4 inch RH TNSR Threading and Grooving Tool Holder is engineered for high‑precision machining environments where reliability and repeatability are paramount. Constructed from hardened steel alloy, the holder resists wear and maintains dimensional stability even under prolonged exposure to coolant and high spindle speeds. The 3/4 inch shank conforms to standard CNC machine interfaces, allowing seamless integration with a wide range of equipment without the need for additional adapters. The insert tip length of 1.00 inch provides ample engagement surface for NG‑R and NT‑R style inserts, while the maximum depth of cut of 0.21 inch enables deep notch creation without compromising tool rigidity.
Designed with a right‑hand (RH) orientation, the holder aligns perfectly with conventional threading strategies, reducing setup time and minimizing the risk of misalignment. The compact geometry reduces overall tool length, improving balance and reducing vibration during high‑speed operations. Each unit undergoes a rigorous quality inspection process that includes dimensional verification, hardness testing, and functional trial runs to ensure that every holder meets SHARS’ exacting standards.

Usage
This tool holder excels in applications such as CNC milling, turning, and multi‑axis machining where notch threading and grooving are required. It is particularly well‑suited for aerospace component fabrication, automotive part production, and precision instrument manufacturing where tight tolerances and surface finish quality are critical. The holder’s robust construction allows it to perform reliably in both dry and wet machining conditions, making it adaptable to a variety of coolant strategies.
Operators will find the holder intuitive to install: simply secure the holder into the machine spindle, insert the appropriate NG‑R or NT‑R insert, and tighten to the recommended torque. The design ensures that the insert remains firmly seated, preventing chatter and tool deflection even during aggressive material removal. The holder’s compatibility with standard 3/4 inch shank tooling means that it can be swapped quickly between different machining operations, enhancing production flexibility and reducing downtime.
