Tegara CAT40 3/4″ x 4″ Face Mill Tool Holder Alloy Steel

Description

Product Overview

The Tegara CAT40 face mill tool holder is engineered to meet the rigorous demands of modern machining operations. Constructed from high‑grade alloy steel that has been hardened to a Rockwell hardness range of 54‑60 HRc, the holder offers exceptional wear resistance and structural integrity even under heavy cutting forces. The shell mill pilot is manufactured to a total indicated runout (T.I.R.) of less than 0.0002 inches, guaranteeing a stable platform for indexable inserts and minimizing vibration during high‑speed milling. All critical surfaces are precision‑ground, delivering a smooth, consistent interface that reduces friction and extends the life of both the holder and the cutting inserts. With a bore diameter of 3/4 inch and a gage length of 4 inches, the CAT40 provides a compact yet robust solution that fits a wide range of milling machines and CNC equipment. The design incorporates a standard shank that aligns perfectly with most spindle noses, allowing for quick tool changes and reducing downtime on the shop floor. This combination of material quality, dimensional accuracy, and thoughtful engineering makes the Tegara CAT40 an ideal choice for manufacturers seeking reliable performance in high‑precision milling applications.

Usage

In industrial environments where productivity and precision are paramount, the Tegara CAT40 face mill holder excels across a variety of applications. It is particularly well‑suited for aerospace component machining, automotive part production, and general metalworking where tight tolerances and repeatable results are required. The holder’s robust construction enables it to handle tough materials such as stainless steel, titanium alloys, and hardened tool steels without compromising accuracy. Operators can employ the holder in both manual milling setups and fully automated CNC machining centers, benefiting from its compatibility with standard indexable insert systems. The 3/4″ bore diameter allows for easy integration with common collet and chuck configurations, while the 4″ gage length provides sufficient rigidity for deep‑cut operations. Whether the task involves face milling large flat surfaces, contouring complex geometries, or performing light finishing passes, the CAT40 delivers consistent chip evacuation and stable cutting conditions. Its design also supports high spindle speeds, making it a versatile tool for high‑speed machining strategies that aim to reduce cycle times while maintaining surface finish quality.
