Accupro 588377 ER32 Collet 19 Mm

Product Description

The ACCUPRO 588377 is an ER32 series collet designed for use in CNC machining centers, milling machines, and manual mills equipped with ER32 collet chucks or toolholders. It accepts a 19 mm shank diameter and provides secure, concentric workholding for cutting tools including end mills, drills, and reamers. The ER32 collet style is one of the most widely used standards in precision machining, offering a balance of gripping range, runout accuracy, and ease of tool changes. Machinists and tool-and-die professionals rely on this collet type for general-purpose and production machining applications.

This collet is suited for use in both manual and CNC milling setups where an ER32-compatible toolholder or collet chuck is already installed. It fits standard ER32 collet nuts and chucks across a broad range of spindle configurations. The 19 mm size is commonly used when holding metric-shank tooling in production and job-shop environments. The collet ships individually in a quantity of one per package.

• 19 mm collet size for metric-shank cutting tools
• Precision ground for accurate tool runout and repeatable setup
• Single-piece package quantity for flexible procurement
• Rated to 1000 pressure units per spec data — consult manufacturer documentation for operating limits

Compatibility

Designed for use with ER32-standard collet chucks and toolholders. No specific machine model compatibility was provided in the product data. Verify that your existing chuck or toolholder is rated for the ER32 collet series before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before inserting the collet, ensure the spindle is fully stopped and the machine is in a locked-out, energy-isolated state per applicable OSHA lockout/tagout procedures. Seat the collet fully into the ER32 collet nut before inserting the cutting tool shank, then thread the assembly onto the toolholder and torque the collet nut using the appropriate ER32 spanner wrenches — do not use makeshift tools that can damage the nut or collet taper. Inspect the collet bore and taper for chips or debris before each use to maintain runout accuracy.
