Precision Heat Shrink Tooling for CNC Machines

Shrink Fit Tool Holders are precision-engineered tool holding systems designed for maximum accuracy and rigidity in high-speed CNC machining. Unlike conventional tool holders, Heat Shrink Tool Holders utilize thermal expansion and contraction principles to secure the cutting tool, providing superior concentricity and eliminating runout.

Our product range includes CAT 40 Shrink Fit tool holders, BT40 Shrink Fit Holders, BT30 shrink fit holders, and universal shrink fit tooling solutions compatible with a wide variety of milling machines and machining centers. For precise installation and removal, we also offer shrink fit tool holder machines or heat shrink machines for tool holders, ensuring consistent and safe performance.

Comparison with Conventional Tool Holders

FAQ

Q1: What is a shrink fit tool holder?
A: A shrink fit tool holder uses thermal expansion to grip the tool shank securely. It provides high precision and eliminates runout during high-speed CNC machining.

Q2: How do I install a shrink fit tool?
A: Using a heat shrink tool holder machine or heat shrink machine for tool holders, the holder is heated to expand, the tool is inserted, and as it cools, it tightly grips the tool.

Q3: What sizes are available?
A: We offer BT30 shrink fit holders, BT40 shrink fit holders, CAT 40 shrink fit tool holders, and customized tooling diameters.

Q4: Can shrink fit holders be used on milling machines?
A: Yes, our shrink fit holders are ideal for collet holder for milling machine and CNC machining centers.

Q5: Are there custom options?
A: Yes, we provide shrink fit tooling customization including taper type, shank diameter, and coatings for specific applications.
