It accepts a 0.5 inch (1\/2 inch) round shank tool and has an overall length of 1.24 inches with an overall diameter of 0.827 inches. The collet operates at a clamping pressure rating of 1800, ensuring consistent tool grip and concentricity during cutting operations. It is typically installed by machinists and CNC setup technicians as part of a precision toolholding assembly.\u003c\/p\u003e\u003cp\u003eThis collet is suited for light to medium-duty machining applications in job shops, production facilities, and maintenance environments. The ER20 series is a widely adopted standard in precision toolholding, and this collet fits within that system to hold drills, end mills, reamers, and other 0.5 inch shank tooling. It is a single-piece component installed directly into an ER20 collet chuck body.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER20 series collet accepts 0.5 inch round shank tooling\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.24 inches for compact chuck assemblies\u003c\/li\u003e\n\u003cli\u003eOverall diameter of 0.827 inches for standard ER20 chuck compatibility\u003c\/li\u003e\n\u003cli\u003e1800 clamping pressure rating for secure tool retention\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.1 pounds for easy handling during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard component for use with ER20-compatible collet chuck bodies accepting 0.5 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC technicians. Always ensure the machine spindle is powered down and at a complete stop before changing collets. The collet should be seated properly in the collet nut before tightening onto the chuck body.
