Description
Meet the Omega Products ER Collet Extension with Castle Nut (UM) and Straight Shank. This extension is built for machinists, engineers, and workshop users who need extra reach from their ER20 collet system, delivering a secure, adjustable connection to extend the working envelope without sacrificing precision, while the straight shank ensures easy compatibility with a wide range of tool holders and machines.
- Secure Castle Nut Connection: The castle nut design provides a secure and adjustable connection, allowing you to tighten or loosen the extension as needed for repeatable clamping and quick setup.
- Extended Reach, 150 mm: Adds 150 mm of length to reach longer workpieces without moving the entire setup, helping you maintain alignment and stability during cuts.
- Wide Tooling Compatibility via Straight Shank: The straight shank design enables easy insertion into a variety of tool holders and machining setups, reducing setup time and increasing flexibility.
With these ER collet extensions, you gain the ability to handle longer parts in a single setup, improving workflow and reducing downtime from tool changes or re-fixturing. The secure castle nut keeps the connection tight under load, the 150 mm extension broadens your machining envelope, and the straight shank supports quick, trouble-free integration with your existing equipment. In short, you get reliable performance, consistent results, and greater versatility across a range of materials and applications.
