High-Speed, Pre-Balanced: Our ER20 Collet Nut's internal clamping ring is expertly designed to minimize imbalance, outperforming standard off-center o-ring designs. It achieves 12,000 RPM without requiring hole drilling, preserving the nut's strength when used on balanced machines. Internal ball bearings in a tapered raceway prevent twisting, ensuring smooth and stable collet collapse around cutting tools. This enhances overall runout and clamping force. Crafted from Taiwan-made ball bearings and balanced to 12,000 RPM, our nut is made from alloy steel, hardened to 55-56 HRC. Precision-ground internal threads and tapers ensure compatibility with most standard ER tool holders, ER collets, and ER nose style collet wrenches.
