SHARS 1/2″ Shank RH TNSR 08-2V Notch Threading & Grooving Tool Holder

Description

Product Overview

The SHARS 1/2″ shank right‑hand TNSR 08‑2V notch threading and grooving tool holder is engineered for high‑precision machining tasks where accuracy and repeatability are paramount. Constructed from hardened steel, the holder features a robust 1/2″ shank that provides a secure, vibration‑free connection to the spindle, ensuring stable operation even under demanding cutting conditions. The right‑hand configuration aligns with standard CNC machine tool orientations, allowing seamless integration into existing setups without the need for additional adapters.

Key specifications include an edge‑to‑insert tip length of 0.75″, which offers ample reach for a wide range of insert sizes while maintaining a compact profile. The maximum depth of cut is 0.138″, enabling the creation of deep, clean threads and grooves in a variety of workpiece materials, from aluminum alloys to hardened steels. The holder supports NG‑R and NT‑R insert styles, giving users flexibility to select the optimal insert geometry for specific applications such as high‑speed threading, heavy‑duty grooving, or fine‑finish operations.

Weighing only 4 ounces, the holder adds minimal mass to the spindle, reducing inertia and improving dynamic response during rapid tool changes. Since its introduction on October 3, 2019, the product has earned a solid reputation among machinists, reflected in a 5‑star rating based on verified customer reviews. Its durability, precision, and ease of use make it a trusted component for both small‑batch production and high‑volume manufacturing environments.

Usage

This tool holder excels in a variety of machining scenarios. In CNC milling centers, it is commonly employed for creating internal and external threads, as well as for producing precise grooves that serve as keyways, slots, or fluid channels. The 0.75″ insert tip length provides sufficient clearance for larger inserts, allowing users to tackle heavy‑cutting operations without sacrificing rigidity. The 0.138″ maximum depth of cut makes it suitable for deep threading applications, such as producing M10‑M20 threads in hardened steel shafts.

Manufacturers in the automotive, aerospace, and medical device sectors rely on this holder for its consistent performance when machining critical components that demand tight tolerances. Its compatibility with both NG‑R and NT‑R insert styles means that users can quickly switch between different cutting geometries to optimize chip evacuation, surface finish, and tool life. The holder’s lightweight design also benefits high‑speed machining, where reduced rotating mass translates to faster spindle acceleration and deceleration, improving overall cycle times.

For maintenance, the holder requires only periodic cleaning of the shank and inspection of the clamping surfaces to ensure a tight fit. Its simple, tool‑free changeover mechanism allows operators to replace inserts quickly, minimizing downtime and keeping production lines running smoothly.
