Shrink Fit Technology
Explore the core benefits and engineering behind shrink fit tool holders — a high-performance solution for CNC machining precision, balance, and reliability.
What is Shrink Fit?
Shrink fit tool holders use thermal expansion to grip cutting tools with extreme precision. By heating the holder, the bore expands to accept the tool shank; as it cools, it contracts, creating a tight and uniform grip with excellent concentricity.
Why Shrink Fit?
Compared to collet or hydraulic holders, shrink fit tool holders provide better balance, longer tool life, and faster tool changes when paired with a shrink fit machine. They're perfect for 3-, 4-, and 5-axis CNC applications that demand micron-level accuracy.
Benefits for You
Shrink fit systems are ideal for high-speed and high-precision machining. They eliminate the need for mechanical clamping parts, reducing vibration and improving surface finish. Whether you're milling, drilling, or finishing, shrink fit holders offer unparalleled rigidity and repeatability.
