R8 18Mm(23/32") Round Collet 7/16-20UNF Thread R8 Precision Round Spring Collet

1. This high-precision R8 collet is machined from 45# carbon steel, hardened for long service life and enhanced durability. Precision ground with small tolerances. The ground and polished surface enhances corrosion resistance and provides a smooth, consistent finish, resulting in clamping and extended tool life.2. The precision round spring collet offers a strong clamping force, a wide clamping range, and is wear-resistant, facilitating easy installation and removal of the chuck at the CNC lathe spindle nose. Precision threaded holes allow for quick connection of the chuck to the spindle. Achieving 0.015 mm accuracy ensures excellent alignment and minimal runout during machining operations.3. This precision collet is primarily used in CNC engraving machines, milling machines, and lathes for holding end mills, drills, engraving bits, and other rotary tools securely. It is suitable for detailed engraving work, precision milling, light machining, and other applications where high accuracy and minimal tool vibration are required.4. Notice - Please ensure this collet is fit for your specific machine’s spindle type and that the tool shank diameter matches the collet size before use.
