Value Collection SC80040967 ER25 Collet Chuck 1 in Straight

Product Description

The VALUE COLLECTION SC80040967 is an ER25 collet chuck designed for use in CNC machining centers, milling machines, and manual mills that accept ER-series collet systems. It features a 1-inch straight shank and a 1-inch projection from the spindle face to the collet nose. Total indicator runout (TIR) is rated at 0.0004 inches, making it well-suited for applications that demand close tolerances and consistent concentricity. The overall length measures 6.1 inches. Machinists and toolroom technicians install this chuck when setting up ER25 collet toolholding assemblies for drilling, reaming, or light milling operations.

This collet chuck is intended for use in machines equipped with a 1-inch straight-shank spindle bore or compatible toolholding interface. It accepts the full range of ER25 collets, which typically cover cutter and toolholder shanks in the ER25 size range. Through-coolant is not supported on this chuck. It is a practical choice for job shops, maintenance machining, and production environments where ER25 toolholding is the standard. Package quantity is 1 unit.

Key Features

• ER25 collet system compatibility for broad toolholder shank coverage
• 1-inch straight shank for direct spindle mounting
• 0.0004-inch TIR for tight-tolerance machining applications
• 1-inch projection from gauge line to collet nose
• 6.1-inch overall length for standard reach requirements
• No through-coolant, simplifying setup where flood coolant is not required

Compatibility

Designed for use with ER25 collets in machines accepting a 1-inch straight-shank toolholder. Specific machine model compatibility was not stated in available product data; verify spindle bore and drawbar specifications before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and locked out before inserting or removing the collet chuck. Clean the shank and spindle bore thoroughly before seating the chuck to prevent runout caused by debris. Torque the collet nut to the collet manufacturer's specification using the appropriate ER25 spanner wrench; do not use improvised tools that could damage the collet nut or chuck body.
