Champion BH4-2000 Tri-Lock 2-inch Quick Change Coolant-Thru Tool Holder ER CN4-25 is a compact CNC milling tool holder designed for fast, repeatable tool changes in congested tooling envelopes, with through-tool coolant delivery. The Tri-Lock mechanism secures tools quickly while preserving preset stick-out accuracy, and it includes a 3/4 NPT coolant port for through-spindle cooling. It uses an ER25 (CN4-25) collet with a clamping range of 1/16" to 5/8" and features a 5/8-18 nose thread, all built around a 2" shank diameter for tight work areas.
