Tegara CAT40 1 x 1.97″ Shell Face Mill Tool Holder 202-5372

Description

Product Overview

The Tegera CAT40 Shell Face Mill Tool Holder is engineered for demanding machining environments where precision, durability, and repeatability are paramount. Featuring a 1.97″ gage length and a 1″ bore, this holder accommodates a wide range of indexable inserts, enabling users to achieve optimal material removal rates while maintaining tight tolerances. Constructed from high‑grade alloy steel hardened to 54‑60 HRc, the holder offers exceptional wear resistance and stability under high spindle speeds and cutting forces.

Every critical surface of the holder is precision‑ground, ensuring perfect alignment of the insert pilot and minimizing run‑out. The shell mill pilot tolerance of less than 0.0002″ guarantees consistent engagement with the workpiece, reducing vibration and extending tool life. The compact design, with a total length of 1.97″, allows for easy integration into tight machining setups, while the robust construction provides confidence in heavy‑duty applications such as aerospace component machining, automotive part production, and general industrial milling.

Additional specifications include a package dimension of 6.02 x 3.54 x 3.03 inches and a weight of approximately 3 pounds, making it convenient for inventory handling and quick tool changes. The holder is not discontinued by the manufacturer, ensuring ongoing availability for maintenance and replacement programs. With a best‑seller rank of #73 in the Face Mill Holders category, the Tegera CAT40 has earned a reputation for reliability among professional machinists.

Usage

This tool holder excels in a variety of machining scenarios. In CNC milling centers, the precise gage length and hardened construction enable high‑speed face milling of aluminum, steel, and exotic alloys with minimal tool deflection. The holder’s design supports both automatic tool changers and manual tool posts, providing flexibility for both high‑volume production lines and small‑batch custom work.

For manual milling operations, the ergonomic shape and balanced weight distribution reduce operator fatigue during extended machining sessions. The holder’s compatibility with standard indexable inserts means users can quickly swap out cutting edges to match material hardness, feed rates, and surface finish requirements. Whether performing roughing passes to remove bulk material or finishing passes to achieve a mirror‑like surface, the Tegera CAT40 delivers consistent performance.

In high‑temperature environments, the alloy steel composition maintains its hardness, preventing softening that could compromise dimensional stability. This makes the holder suitable for machining titanium alloys and high‑temperature nickel‑based superalloys, where thermal stability is critical. Additionally, the holder’s compact profile allows it to be used in tight fixturing arrangements, such as deep‑well milling or machining of internal features where space is limited.
