BBT40 ER Collet Chucks

Description

BBT40 ER Collet Chuck, 100mm Gauge Length – Dual Contact Precision for CNC Machining

The BBT40 ER Collet Chuck is engineered to provide unparalleled accuracy and stability in high-speed CNC machining. Known for its dual-contact (Big Plus BT) design, also referred to as Dual Contact, this collet chuck makes contact at both the spindle taper and flange face. This enhanced contact area boosts rigidity, making it superior to standard BT holders, especially in high-precision or heavy-load machining environments.
