Attention machinists and CNC enthusiasts! This ER20 spring collet is here to make your tool-holding life easier. With an 11mm clamping diameter, it's perfect for securing end mills, drills, and engraving bits in your CNC router, milling machine, or lathe.
Made from tough 65Mn spring steel, it offers high wear resistance, great elasticity, and strong clamping force—so your tools stay put during high-speed runs. The precision is tight, around 0.005mm (0.0002 inches), which means less run-out and cleaner cuts.
To use it, just slide the collet into the nut, fit them into your chuck or spindle, insert your tool, and tighten with a wrench. When you need to switch tools, loosen the nut and pop it out. Simple!
This collet is widely used in CNC machining, engraving, 5-axis work, and other precision applications. It comes packed in a plastic box to keep it safe. Whether you're a hobbyist or a pro, having the right collet on hand makes all the difference. Just double-check your machine's compatibility before ordering. Happy machining!
