The Mafell Collet Chuck Adapter ER 16 (Ref. No. 208109) with included union nut is a precision tooling accessory engineered for Mafell milling motors, such as the FM 1000 PV-WS and NC-WS series. Designed to expand tooling compatibility, this ER 16 collet adapter enables the secure and concentric mounting of standard ER 16 routing and milling bits up to a maximum speed of 16,000 RPM.

Manufactured to strict industrial tolerances, the adapter ensures high runout accuracy, minimizing vibration and maintaining clean cutting performance during high-speed CNC milling and routing operations. The included ER 16 union nut provides secure clamping retention for safe tool changing and reliable operation in gantry and fixed-mount applications.
