Shrink Fit Chuck
BT50 Shrink Fit Tool Holders
Product Introduction
• Ultimate Concentricity (T.I.R < 0.003mm):The monoblock geometric construction eliminates tolerances from multi-component stacking, ensuring the tool's rotation center is perfectly aligned with the spindle.
• Powerful and Uniform Clamping Force:The 360° full-circumference shrink-fit clamping provides rigidity far superior to traditional collets, significantly enhancing overall cutting stability.
• Excellent Dynamic Balance:The symmetrical design—free of nuts or slots—minimizes centrifugal vibration during high-speed rotation, protecting the machine spindle and extending its service life.
• Slender Interference Advantage:Featuring thin wall thickness at the front end and multiple taper options, the holder easily accesses narrow, deep cavities for machining while avoiding workpiece interference.
