ER COLLETS

About ER COLLETS

An ER Collet from the brand TURNMAX, manufactured by Turnmax Machine Tools, is a high-precision tool-holding device designed for CNC milling and turning machines. It is a critical component for securely clamping cutting tools with a cylindrical shank, such as end mills, drills, and reamers.

Key Features and Design

• Wide Clamping Range: The primary advantage of a TURNMAX ER collet is its wide collapsing range, which allows a single collet to hold a variety of tool shank diameters. This reduces the number of collets needed and simplifies tool changes.

• High Precision: These collets are manufactured to strict international standards like DIN 6499. They are precision-ground to achieve minimal runout, often less than 0.005mm, which ensures high accuracy in machining and extends tool life.

• Secure Grip: The multi-slit design provides even pressure around the entire circumference of the tool, ensuring a powerful and concentric grip that prevents the tool from slipping during high-speed and heavy-duty cutting operations.

• Durable Construction: TURNMAX ER collets are made from high-quality, hardened alloy steel, making them resistant to wear and tear and suitable for long-term, high-performance use.
