Iscar 5623092 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ISCAR 5623092 is a solid carbide corner radius end mill built for demanding material removal in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It features a 1/2 inch mill diameter, a 0.023 inch corner radius, and four flutes with a variable helix and variable index geometry. The AlTiN PVD coating provides heat resistance at elevated cutting speeds. This is a single-end, centercutting tool rated for both roughing and finishing operations. It belongs to ISCAR's ECI-H4R-CF Chatter Free series, designed specifically to suppress vibration during aggressive cuts.

This end mill is suited for CNC machining centers in job shop and production environments where chatter control and surface finish consistency are priorities. The variable helix geometry disrupts harmonic resonance, making it effective in long-reach or deep-pocket applications where standard end mills lose stability. The Weldon flat shank ensures positive drive in side-lock toolholders. Typical users include machinists and tooling specialists working in aerospace, die and mold, and general metalworking applications.

Key Features

• Variable helix and variable index geometry for chatter suppression in the ECI-H4R-CF series
• AlTiN PVD coating for thermal resistance in high-speed and dry cutting conditions
• Centercutting design allows plunge entry into the workpiece
• Weldon flat shank provides positive engagement in side-lock toolholders
• Submicron carbide grade supports cutting of hard and exotic alloys
• Rated for roughing and finishing in a single tool across P, M, K, S, and H material codes

Compatibility

Designed for use with standard side-lock toolholders accepting a 1/2 inch Weldon flat shank. Suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials per ISO material codes P, M, K, S, and H.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and undamaged before inserting the shank. Confirm the Weldon flat is properly aligned with the set screw before torquing the toolholder. Verify runout with a dial indicator after clamping, as excessive runout will shorten tool life and reduce surface finish quality.
