The Omega Products BT40 ER Collet Chuck delivers stable tool holding for CNC operators running BT40 spindles in precision milling and drilling work. With its ER25 capacity, 120mm gauge length, and G2.5 balancing at 20,000 RPM, it supports accurate cuts without excessive vibration.

• Taper Interface: BT40 shank mates directly with standard BT40 machine spindles for reliable seating
• Collet Size: ER25 accepts common tool diameters and provides strong, even clamping force
• Speed Rating: Balanced to G2.5 for operation up to 20,000 RPM while keeping runout low
• Gauge Length: 120mm projection allows extended reach on deep pockets and contours
• Coolant Form: Form AD design routes coolant through the tool for better chip removal

This collet chuck reduces tool deflection and helps maintain consistent surface finishes, making it practical for production runs where repeatability matters. The balanced construction also extends tool life by limiting vibration during longer cuts.
