End Mill Holder Cylindrical Extension Shank Side Fixed SLD Small Diameter Cutter


Features End Mill Holder.

A cylindrical end mill holder typically refers to a tool holder used for securely holding cylindrical shank end mills in machining operations. While the specific features may vary depending on the manufacturer and model, here are some common features you might find in a cylindrical end mill holder:

Shank Compatibility: Cylindrical end mill holders are designed to accommodate cylindrical shank end mills of specific diameters. They may come in various sizes to accommodate different shank diameters.

Precise Fit: The holder is engineered to provide a precise fit between the holder and the end mill shank, ensuring optimal stability and accuracy during machining.

Collet or Set Screw Mechanism: Cylindrical end mill holders may utilize either a collet or set screw mechanism to secure the end mill in place. A collet mechanism utilizes a collet nut to clamp the end mill, while a set screw mechanism uses a set screw to tighten against the flat portion of the end mill shank.

High-Quality Construction: Cylindrical end mill holders are typically made from high-quality materials such as hardened steel or carbide. This ensures durability, rigidity, and resistance to wear and deformation during machining operations.

Balanced Design: To minimize vibration and maximize cutting performance, cylindrical end mill holders may have a balanced design. This helps to achieve smoother and more efficient milling operations.

Standard or ER Collet Type: Some cylindrical end mill holders are compatible with standard collets, while others are designed to work with ER (Extended Range) collets. ER collets provide a larger clamping range, allowing for greater flexibility in tool size.

Shank Projection: Cylindrical end mill holders may have a specific shank projection length, which determines how far the end mill extends from the holder. This projection can impact the reach and accessibility of the tool in certain machining applications.
