Accupro 785011 ER32 Collet 0.75 Inch

Product Description

The ACCUPRO 785011 is an ER32 series collet designed to hold round workpieces and cutting tools in CNC machining centers, milling machines, lathes, and other spindle-driven equipment. The collet accepts a nominal 0.75 inch (3/4 inch) tool shank with a minimum collet capacity of 0.719 inches, providing a secure, concentric grip during cutting operations. Weighing 0.35 pounds, this collet fits standard ER32 collet chucks and is used by machinists and CNC operators in production and job-shop environments. Its compact dimensions make it straightforward to seat and torque into compatible chuck bodies.

This collet is suited for use in metalworking, woodworking, and general machining applications where an ER32 collet chuck is already installed. It is appropriate for both light and moderate-duty cutting operations involving end mills, drills, reamers, and similar round-shank tooling at the 3/4 inch nominal diameter. The ER32 system is widely used in residential shop and commercial production settings alike. Tooling setup is performed by machinists and CNC technicians as part of routine tool changes or new job setups.

Key Features

• ER32 collet series for compatibility with standard ER32 chuck bodies
• Nominal collet size of 0.75 inches (3/4 inch decimal inch designation)
• Minimum collet capacity of 0.719 inches for secure clamping across the grip range

Compatibility

Designed as an OEM-style replacement or standard collet for use with ER32 collet chuck bodies in CNC and manual spindle applications requiring a 0.75 inch nominal tool holding capacity.

Installation Notes

Installation is performed by machinists or CNC technicians during tooling setup. Always power down and lock out the machine spindle before inserting or removing collets. The collet should be seated into the chuck nut before insertion into the chuck body, then tightened to the chuck manufacturer's specified torque using an appropriate ER collet wrench. Inspect the collet bore and seating surfaces for debris or damage before each use to maintain concentricity and safe clamping force.
