The BT50 ER Collet Chuck for ER40 tooling is a precision tool holder designed for BT50 spindle systems. It securely clamps ER40 cutting tools, delivering stability and accuracy throughout milling, drilling, and finishing tasks in workshops, job shops, and production environments.

Operating from 15,000 to 25,000 RPM, this collet chuck integrates tight tolerance levels (G2.5 and G6.3) that ensure excellent tool concentricity and minimal runout. The result is consistent tool guidance, smoother cuts, and better surface finishes across a wide range of materials.

• High-precision concentricity and minimal runout: G2.5 and G6.3 precision ratings translate into consistent tool alignment, improving cutting performance and surface finish across jobs.
• Wide RPM range for versatile machining: 15,000–25,000 RPM supports a broad range of ER40 tooling and materials, enabling fast setup and efficient production without swapping chucks.
• Rigid BT50 interface with 100 mm gauge length: Form AD/B design and a 100 mm gauge length provide stable engagement, reduced deflection, and longer tool life through repeatable clamping.

With its precise clamping and sturdy BT50 mounting, this ER40 collet chuck helps you move faster between jobs, achieve repeatable results, and minimize scrap due to runout or tool deflection. Whether you're prototyping, producing, or maintaining tight tolerances, it provides dependable performance you can trust day in and day out.
