Collet Chuck — ER40 Series

A precision ER40 collet chuck with a hardened and ground taper bore achieving less than 0.0002" TIR at the collet nose, providing rigid and accurate tool holding for CNC milling centers running end mills, drills, and reamers in aerospace alloys, hardened steels, and titanium.

• Rated for spindle speeds up to 15,000 RPM
• Short-nose design maximizes Z-axis clearance for deep-pocket milling and 5-axis simultaneous machining
• Available in three spindle-mount configurations for the most common CNC machining center spindle standards
• Less than 0.0002" TIR at the collet nose for precision tool holding

When your aerospace program demands tenths, your toolholder needs to deliver.
