Shrink Fit Chuck
BT40 Shrink Fit Tool Holders
Product Introduction
• BT40 Shrink Fit Toolholders:Ultimate Concentricity (T.I.R < 0.003mm)
The monoblock geometric construction eliminates tolerances caused by 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:With a slim wall thickness at the front end and multiple taper options, the holder easily accesses narrow, deep cavities while avoiding interference with the workpiece.
