Iscar 4500612 Shrink-fit Tool Holder Adapter ER32

Product Description

The ISCAR 4500612 is a shrink-fit tool holder adapter designed for CNC machining centers and milling applications requiring precise, high-rigidity tool retention. It features an ER32 taper shank configuration with a 0.125 inch hole diameter, a 1.5 inch projection, and a 0.63 inch clamping depth. Through-coolant capability directs cutting fluid directly to the tool tip, supporting high-speed and deep-reach operations. This adapter is installed by CNC machinists and tooling technicians in production and job shop environments where runout control and secure tool clamping are critical to surface finish and tool life.

The 4500612 is suited for use in shrink-fit tooling setups on vertical and horizontal machining centers. Its ER32 taper shank interfaces with compatible shrink-fit holders and collet chuck systems. The 0.125 inch bore accommodates small-diameter end mills, drills, and reamers commonly used in precision contouring and finishing passes. Through-coolant support makes it well-suited for deep-pocket milling and high-temperature alloy cutting where coolant delivery at the cutting edge is required.

Key Features

• ER32 taper shank for broad compatibility with standard shrink-fit tooling systems
• 0.125 inch hole diameter for small-diameter cutting tool retention
• 1.5 inch projection for reach into confined or deep-pocket features
• 0.63 inch clamping depth provides secure axial tool grip
• Through-coolant design channels fluid directly to the cutting zone

Compatibility

Designed as an OEM-style replacement adapter for ER32 taper shank shrink-fit tooling systems used on standard CNC machining centers.

Installation Notes

Installation and removal of shrink-fit adapters requires a dedicated induction heating unit to expand the bore before tool insertion — never use open flame or impact tools on shrink-fit components. Power down the machine spindle and confirm all motion is stopped before changing tooling. Verify adapter seating and runout with a dial test indicator before resuming cuts. Follow the machine tool builder guidelines and applicable ANSI or shop safety standards for tooling changeouts.
