Iscar 5623187 Corner Radius End Mill Head

Product Description

The ISCAR 5623187 is a corner radius end mill head designed for use in modular end milling systems. This interchangeable cutting head mounts to a compatible shank body and delivers radiused corner geometry at the cutting edge, which reduces stress concentration and extends tool life compared to sharp-corner profiles. It is suited for milling operations in ferrous and non-ferrous materials where edge chipping must be minimized. Machinists and CNC operators in job shops, toolrooms, and production facilities are the typical end users. This head ships as a single unit with a minimum order quantity of one.

Corner radius end mill heads like the 5623187 are used in vertical and horizontal machining centers for profile milling, pocket milling, and finishing passes where a controlled corner radius is required by part geometry or drawing callout. The fixed-index design means the head seats at a defined angular position on the shank, ensuring repeatable runout on head changes without re-indicating. This makes it appropriate for production environments where tool changes must be fast and consistent.

Key Features

• Corner radius cutting geometry reduces edge chipping and extends tool life in demanding milling applications
• Fixed-index (non-variable index) design provides repeatable seating position on compatible modular shank bodies
• Non-variable helix geometry delivers consistent chip evacuation across the cutting edge
• Single-piece packaging with a minimum order quantity of one for flexible procurement
• Interchangeable head format reduces tooling cost by allowing shank body reuse

Compatibility

Designed as an OEM-style replacement or production-use cutting head for modular end milling systems that accept ISCAR-compatible interchangeable end mill heads. Confirm shank interface, head diameter, and thread specification against your existing tooling setup before ordering.

Installation Notes

Installation of interchangeable end mill heads should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is removed from the machine before changing heads. Use the manufacturer-specified torque wrench and interface key for head engagement — do not use makeshift tools that may damage the seating surface or thread. Inspect the mating surfaces of both the head and shank body for chips or debris before assembly to ensure proper seating and runout.
