BT Shrink Fit Tool Holder

This BT shrink fit tool holder is a high-precision clamping solution for CNC machining centers, designed to deliver excellent concentricity, rigid gripping and high-speed stability for solid carbide cutting tools. It is widely suitable for milling, drilling, reaming and fine finishing operations in precision metal cutting.

Key Performance Features

1. High Precision Clamping

Shrink fit technology provides uniform 360° clamping force around the tool shank, ensuring excellent concentricity and minimal runout for high-precision machining.

2. Strong Gripping Force

The thermal expansion and contraction principle creates a tight, slip-free connection between the holder and the cutting tool, making it suitable for heavy cutting, high-speed milling and difficult-to-machine materials.

3. High Speed Stability

Precision-balanced structure helps reduce vibration during high-speed rotation, improving surface finish, extending tool life and lowering machining noise.

4. Durable Alloy Steel Construction

Made of high-quality alloy steel and precision ground, the holder offers high rigidity, wear resistance and long-term reliability under continuous workshop use.

5. Clean Chip Evacuation

Smooth body design reduces chip accumulation around the clamping area, helping maintain consistent clamping accuracy during long production runs.

Applications

Ideal for mold machining, aerospace components, automotive parts, general machinery and precision fixture manufacturing. Suitable for processing steel, stainless steel, alloy steel, aluminum and copper materials.
