Value Collection SC75980763 ER32 Collet Chuck Straight Shank

Product Description

The VALUE COLLECTION SC75980763 is an ER32 straight-shank collet chuck designed for use in CNC machining centers, manual mills, and drill presses that accept ER-style toolholding systems. It features a 1-inch projection and a 1-1/2 inch straight shank diameter, providing a rigid, repeatable tool-holding interface for milling, drilling, reaming, and tapping operations. The chuck holds a total indicated runout (TIR) of 0.0004 inches, making it suitable for applications where concentricity and surface finish are critical. Overall length is 6.2 inches. Machinists and tool-room technicians rely on this style of chuck for its broad collet range and straightforward setup on standard toolholding equipment.

This collet chuck fits standard ER32 collets and is suited for use in production and job-shop environments running light to medium-duty machining operations. The straight shank configuration allows direct installation into compatible spindle bores or toolholding blocks. It is appropriate for both ferrous and non-ferrous workpiece applications where low runout and secure collet engagement are required. Through-coolant is not supported on this chuck.

Key Features

• ER32 collet system compatibility for a wide range of collet sizes
• Straight shank design for direct spindle or block mounting
• 1-inch projection for close-clearance tooling setups
• 0.0004 inch TIR for high-concentricity tool holding
• 6.2 inch overall length suits standard toolholding configurations
• No through-coolant passages — suited for dry or flood coolant from external nozzles

Compatibility

Designed as an OEM-style replacement or direct-fit collet chuck for machine spindles and toolholding blocks that accept ER32 straight-shank collet chucks with a 1-1/2 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the collet chuck. Ensure the spindle bore and shank are clean and free of chips or burrs before seating the chuck. Follow the machine manufacturer torque specifications for any retention hardware — do not use values from other toolholding assemblies.
