Iscar 4501934 ER32 Collet Chuck Straight Shank

Product Description

The ISCAR 4501934 is an ER32 collet chuck with a straight shank, designed for use in CNC machining centers and milling machines where precise tool holding and concentricity are required. It accepts ER32 collets with a clamping capacity range of 0.08 to 0.789 inches, covering a wide variety of tool shank diameters. The chuck features through-coolant capability, delivering coolant directly to the cutting zone via through-spindle delivery. Overall length is 4.462 inches with a projection of 2.087 inches. A licensed machinist or tooling technician installs and maintains this chuck as part of a machine spindle tooling assembly.

This ER32 collet chuck is suited for production machining environments where consistent clamping force and coolant delivery are critical to tool life and surface finish. The straight shank configuration fits standard spindle bores. The 1.25-inch shank diameter and 1.968-inch nose diameter make it compatible with common milling and machining center spindle configurations. It is appropriate for both roughing and finishing operations where ER32 collet tooling is already in use on the shop floor.

Key Features

• ER32 collet system with capacity range of 0.08 to 0.789 inches
• Through-coolant design with through-spindle coolant delivery
• Straight shank with 1.25-inch shank diameter
• Projection of 2.087 inches for controlled reach into the workpiece
• Wrench-actuated collet clamping for secure, repeatable tool holding
• Overall length of 4.462 inches for dimensional predictability in tool length offsets

Compatibility

Designed for use with ER32 collets in straight-shank spindle tooling applications on CNC milling machines and machining centers that accept a 1.25-inch straight shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before installing or removing the chuck. Use the appropriate ER32 collet wrench and spanner to achieve proper clamping torque on the collet nut. Verify through-coolant passages are clear and that spindle coolant connections are properly sealed before resuming machine operation.
