Accupro 587303 ER16 Collet 1.50mm 0.059 Inch

Product Description

The ACCUPRO 587303 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and routing applications. It accepts a nominal collet size of 1.50mm (0.059 inches) with a minimum collet capacity of 1.0mm (0.0393 inches), allowing a small range of clamping flexibility around the nominal size. The overall length is 27.0mm and the total indicator runout (TIR) is rated at 0.01mm, making it suitable for applications where concentricity and tool accuracy directly affect finished-part quality. Machinists and CNC operators install this collet as part of a standard ER16 collet chuck assembly.

This collet is used in shops performing light to medium milling, drilling, and engraving operations where small-diameter tooling is common. The ER16 series is one of the most widely used collet standards in precision machining, found in both manual and CNC spindles across production and job-shop environments. The 587303 is appropriate when working with small-shank end mills, drill bits, and router bits in the sub-2mm range.

Key Features

• ER16 collet series for use with standard ER16 collet chucks
• 1.50mm nominal collet size with 1.0mm minimum capacity for clamping range flexibility
• 0.01mm TIR for high concentricity and reduced tool runout
• 27.0mm overall length suits compact ER16 toolholding assemblies
• Single-piece packaging with a minimum order quantity of one

Compatibility

Designed as an OEM-style replacement or standard fitment collet for ER16 collet chuck systems requiring 1.50mm nominal tool clamping.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always ensure the spindle is fully stopped and the machine is in an e-stop or lockout-tagout state before changing collets. Clean the collet bore and chuck taper before seating to prevent contamination-related runout errors. Use the appropriate ER16 collet nut and torque wrench recommended by the chuck manufacturer for proper clamping force.
