Iscar 4500563 Shrink-fit Tool Holder Adapter ER32

Product Description

The ISCAR 4500563 is a shrink-fit tool holder adapter designed for use in CNC machining centers and milling applications. It features an ER32 taper shank configuration and accepts tooling with a 0.25 inch hole diameter. With a projection of 2.5 inches and a nose diameter of 0.7 inches, this adapter positions cutting tools at consistent reach from the spindle face. Through-coolant capability directs cutting fluid directly to the tool tip, supporting thermal management and chip evacuation in demanding cutting operations. This adapter is installed and serviced by machinists and CNC tooling technicians.

This shrink-fit adapter is suited for precision machining environments where tool runout control and rigid clamping are required. It is appropriate for high-speed milling, drilling, and boring operations in both production and job-shop settings. The ER32 taper shank interfaces with compatible spindle systems, and the through-coolant feature supports operations in ferrous and non-ferrous materials where heat buildup and chip control are priorities. Clamping depth measures 0.97 inches, providing secure engagement with the toolholder body during operation.

Key Features

• ER32 taper shank for interface with compatible spindle systems
• 0.25 inch hole diameter accommodates standard cutting tool shanks
• 2.5 inch projection for controlled tool reach from spindle face
• Through-coolant design delivers fluid directly to cutting zone
• 0.97 inch clamping depth for secure tool retention
• 0.7 inch nose diameter for clearance in tight-tolerance applications

Compatibility

Designed as an OEM-style replacement adapter for CNC machining centers and milling spindles accepting ER32 taper shank toolholders with through-coolant capability.

Installation Notes

Installation of shrink-fit tool holder adapters requires a dedicated induction heating unit to thermally expand the bore before tool insertion — never force tooling into a cold bore. Ensure the spindle and coolant supply are fully de-energized and depressurized before removing or installing the adapter. A qualified machinist or CNC tooling technician should verify shank seating and runout with a dial indicator after assembly. Follow machine tool manufacturer torque and clamping specifications for the spindle interface.
