BTDC Slim-fit Collet Chuck (JIS-B 6339)

Product Description

The  Tool Holder is a high-precision, high-rigidity clamping device for CNC machining centers, milling machines, and lathes. It utilizes a pull-back locking mechanism to ensure extreme stability and accuracy during high-speed rotation, making it ideal for heavy-duty cutting and precision machining.

Product Advantages

The  Tool Holder demonstrate outstanding advantages in modern CNC machining due to their unique structure and precision engineering. Firstly, their high-rigidity clamping system significantly reduces tool vibration, ensuring stable machining processes—especially for high-precision components (e.g., molds, aerospace parts)—thereby improving surface finish. Secondly, the pull-back locking mechanism delivers stronger gripping force, preventing tool slippage even during heavy-duty cutting (e.g., titanium alloys or hardened steels), enhancing operational safety.

Additionally, the optimized dynamic balance design maintains low vibration at high speeds (over 20,000 RPM), extending both tool and spindle lifespan. Compared to traditional collet chucks, pull-back tool holders enable faster tool changes and support international standards (HSK, BT, etc.), seamlessly integrating with high-end machining centers to reduce downtime and boost productivity.

Optional Accessories

The  Tool Holder can be equipped with optional pull-back collets to accommodate various tool clamping requirements. Made of high-strength alloy steel and processed with precision grinding and heat treatment, these collets ensure high rigidity and wear resistance. The internal taper design provides perfect alignment with the tool holder, delivering enhanced clamping force and superior concentricity (≤0.005mm), making them ideal for precision milling, drilling, and tapping applications. Users can select collets based on tool shank diameters (e.g., φ6mm, φ10mm, φ16mm) for quick tool changes and improved machining efficiency. Some models also feature a dust-proof design to prevent chip ingress, extending service life.
