Accupro 587373 ER32 Collet 0.59 Inch 15mm

Product Description

The ACCUPRO 587373 is an ER32 collet designed for precision toolholding in CNC machining centers, milling machines, and lathes equipped with ER32-compatible collet chucks. Sized at 0.59 inches (15.00 mm), it accepts shank diameters down to a minimum capacity of 0.551 inches (14.0 mm), giving operators a functional clamping range suited to a variety of cutting tools and workholding applications. The collet holds a total indicator runout (TIR) of 0.01 mm, making it appropriate for finish milling, drilling, reaming, and other operations where concentricity directly affects surface quality and tool life. Machinists, toolroom technicians, and CNC operators install this collet as part of standard spindle setup.

This collet fits ER32 collet chucks found on a wide range of machining equipment in both production and job-shop environments. It is well suited for light to medium-duty cutting operations where consistent grip force and low runout are required. Common applications include milling with carbide end mills, drilling with straight-shank drills, and reaming operations where bore accuracy is critical. The ER32 series is one of the most widely used collet standards in the industry, making this collet a common stock item in machine shops of all sizes.

Key Features

• ER32 collet series with 0.59 inch (15.00 mm) nominal collet size
• Minimum collet capacity of 0.551 inches (14.0 mm) for a usable clamping range
• 0.01 mm TIR for consistent concentricity across finish and semi-finish operations
• Compatible with any ER32-standard collet chuck or toolholder
• Single-piece package quantity suitable for individual replacement or tooling buildout

Compatibility

Designed as a standard ER32-series collet for use with any ER32-compatible collet chuck or toolholder. Specific equipment compatibility depends on the chuck or spindle nose installed on the machine.

Installation Notes

Installation is performed by a machinist or toolroom technician during spindle or toolholder setup. Before seating the collet, ensure the spindle is powered down and the machine is in a safe, locked-out state per applicable shop safety procedures. Clean the collet bore and chuck body of chips and coolant before insertion to maintain TIR performance. Torque the collet nut to the chuck manufacturer's specification using the appropriate ER spanner wrench — do not overtighten or use makeshift tools, as this can distort the collet body and compromise runout.
