Description
Product Overview
The DA100 Collet Chuck Extension is engineered to provide a seamless increase in tool reach while maintaining the precision and reliability expected from high‑quality workholding accessories. Featuring a 1‑inch straight shank, this extension adds a total overall length of 5½ inches, allowing users to access deep‑set workpieces and perform operations that would otherwise be constrained by standard chuck dimensions. Constructed from hardened steel, the extension offers exceptional durability, resisting wear and deformation even under demanding machining conditions. The precision‑machined surfaces ensure a tight, wobble‑free fit with compatible collet chucks, delivering consistent torque transmission and reducing the risk of slippage during high‑speed operations. Designed to integrate effortlessly with M & J Tooling’s existing collet systems, the DA100 extension enhances versatility across a broad range of applications, from CNC milling to manual drilling and hobbyist projects.
Usage
Professionals in the manufacturing sector, as well as dedicated hobbyists, will find the DA100 extension indispensable for tasks that demand extended reach without compromising stability. In CNC machining environments, the extension enables deeper drilling into workpieces, facilitating the creation of blind holes and internal features that are otherwise inaccessible. In manual workshops, the added length allows operators to maneuver tools into confined spaces, such as engine blocks, gear housings, and intricate assemblies, improving efficiency and reducing the need for multiple tool changes. The extension’s robust construction makes it suitable for high‑torque applications, including tapping, reaming, and precision grinding, where maintaining a secure grip is critical. Additionally, its compatibility with a variety of collet sizes ensures that users can adapt the extension to different spindle configurations, making it a flexible solution for both small‑scale prototyping and large‑volume production.

FAQ
What collet sizes are compatible with the DA100 extension?
The extension is designed to work with standard 1‑inch collet chucks commonly used in CNC and manual machining setups. It also fits many interchangeable collet systems that accept a 1‑inch shank, providing broad compatibility across different machine brands.
Can the extension be used for high‑speed drilling?
Yes. The hardened steel material and precision machining allow the extension to maintain stability at high spindle speeds, making it suitable for drilling, tapping, and reaming operations where accuracy and rigidity are essential.
How do I ensure a proper fit and avoid slippage?
Before installation, clean both the collet chuck and the extension’s shank to remove debris or oil. Insert the extension fully into the collet, then tighten the chuck according to the manufacturer’s torque specifications. This ensures a tight, secure connection that prevents movement during operation.
Is there a warranty on the DA100 extension?
Yes. M & J Tooling offers a one‑year limited warranty covering material defects and workmanship. Should any issues arise within the warranty period, contact our support team for a replacement or repair.
What maintenance is recommended for the extension?
Regularly inspect the shank and collet interface for wear or damage. Clean the surfaces after each use and apply a light coating of machine oil to protect against corrosion. Replace the extension if you notice significant wear that could affect performance.
