BBT30 ER16 Collet Chuck, 70mm – Dual Contact Precision Tooling

Description

BBT30 ER16 Collet Chuck, 70mm Gauge Length – High-Speed, Precision CNC Tooling

The BBT30 ER16 Collet Chuck, with a 70mm gauge length, 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.
