Tegara CAT40 1-1/2 x 2.4″ Shell Face Mill Tool Holder Alloy Steel

Description

Product Overview

The Tegara CAT40 shell face mill tool holder is engineered for high‑precision milling environments where reliability and repeatability are paramount. Constructed from a premium alloy steel that has been hardened to a Rockwell hardness of 54‑60 HRc, the holder offers exceptional resistance to wear and deformation even under the most demanding cutting forces. Every critical surface of the holder is precision‑ground, ensuring a perfect fit with the shell mill pilot and eliminating run‑out that could compromise part quality. The 1‑1/2″ bore diameter and 2.4″ gage length provide a compact yet robust footprint, allowing it to be used in a wide range of CNC machines without sacrificing rigidity. Designed with a T.I.R (Tool Interface Roughness) of less than 0.0002″, the holder delivers a seamless transfer of torque and minimizes vibration, which translates into smoother cuts and longer tool life. The combination of hardened alloy steel, tight tolerances, and precision‑ground surfaces makes the CAT40 a trusted component for manufacturers seeking consistent performance across high‑volume production runs.

Usage

In modern machining centers, the Tegara CAT40 is most commonly paired with indexable shell face mills for finishing operations on aerospace‑grade alloys, automotive components, and high‑strength steel parts. Its compact size allows it to be mounted on standard spindle heads, making it suitable for both vertical and horizontal machining centers. The holder excels in applications that require precise surface finishing, such as creating flat faces on forged components, machining large‑diameter workpieces, and performing light‑to‑medium roughing passes where stability is essential. Because the holder’s design minimizes run‑out, it is also ideal for high‑speed machining where any deviation can lead to chatter or premature tool wear. Users in the aerospace and defense sectors appreciate the holder’s ability to maintain tight tolerances over long production cycles, while automotive manufacturers benefit from its durability when machining high‑volume engine blocks and transmission housings. The CAT40’s compatibility with standard shell mill pilots means it can be quickly swapped out in tool changers, reducing downtime and increasing overall equipment effectiveness.

Why Choose Us

Choosing the Tegara CAT40 means selecting a product that has been rigorously tested to meet the exacting standards of industrial machining. Shars Tool, the manufacturer, has a long history of producing high‑quality cutting tool components, and each holder undergoes a multi‑stage quality assurance process that includes hardness verification, dimensional inspection, and surface finish analysis. The alloy steel composition is carefully balanced to provide both hardness and toughness, ensuring that the holder can absorb shock loads without cracking. In addition, the precision‑ground surfaces are inspected with high‑resolution metrology equipment to guarantee a fit that is within microns of the specified tolerance, reducing the risk of misalignment and improving overall machining accuracy.

FAQ

What size shell mills are compatible with the CAT40 holder?

The CAT40 is designed for shell face mills that have a 1‑1/2″ bore diameter. It works with a wide range of mill lengths, typically up to 4″ in overall length, making it suitable for both small and medium‑size face milling applications.

Can the holder be used in high‑speed machining environments?

Yes. The combination of hardened alloy steel and precision‑ground surfaces provides the rigidity needed for high‑speed operations. The low T.I.R value helps to dampen vibration, allowing the holder to maintain stability at elevated spindle speeds.

Is the CAT40 holder interchangeable with other brands?

While the holder follows standard dimensions for shell face mill pilots, it is always recommended to verify compatibility with the specific mill and machine tool you are using. The holder’s design adheres to industry standards, but checking the manufacturer’s specifications ensures optimal performance.

What maintenance is required to keep the holder performing at its best?

Regular cleaning of the holder’s surfaces to remove chips and coolant residue is essential. Periodic inspection for wear or damage, especially after extended high‑load machining, will help maintain accuracy. Re‑grinding of the critical surfaces can be performed by qualified service centers if needed.

Does Tegara provide any after‑sales service for the CAT40?

Yes. Tegara offers technical assistance, replacement parts, and a limited warranty covering material defects. Our customer service team is available to answer questions, provide setup guidance, and help troubleshoot any issues that arise during use.
