The Omega BT50 Shrink Fit Chuck with a G2.5 precision rating is engineered for high-speed machining that demands exceptional tool holding. Designed for engineers, machinists, and serious hobbyists, it securely grips tool shanks while delivering outstanding concentricity at speed, so you get consistent, accurate cuts.
The shrink-fit design uses heat to expand the chuck and firmly grip the tool shank, providing stability and effective vibration damping. This reduces tool deflection, supports better surface finishes, and helps you maintain tight tolerances even during demanding milling tasks.
- G2.5 Precision Concentricity: With a G2.5 precision rating, this BT50 shrink fit chuck delivers exceptional tool concentricity and minimal runout, ensuring consistent, accurate results across every pass.
- Heat-Expanded Shrink-Fit for Stable Tool Holding: The shrink-fit design uses heat to expand the chuck so it firmly grips the tool shank, providing superior stability and vibration damping that reduces deflection and improves surface finish.
- High-Speed Capability up to 25,000 RPM with BT50 Interface: Ready for demanding milling tasks, it operates up to 25,000 RPM and accommodates 4 mm tool shanks with a long 160 mm body for extended reach and rigidity.
This combination of precision, secure grip, and high-speed capability translates into real-world advantages: tighter tolerances, smoother surface finishes, fewer tool changes, and more consistent productivity across the shop floor. The BT50 shrink-fit design delivers reliable performance at top speeds, and the 160 mm reach supports deeper pockets and challenging layouts, all built for durable, long-lasting operation.
