Iscar 5620324 Corner Chamfer End Mill 0.188in 4 Flute

Product Description

The ISCAR 5620324 is a solid carbide corner chamfer end mill designed for high-performance material removal in demanding machining applications. It measures 0.188 inches in diameter with a 3/16-inch straight-cylindrical shank and an overall length of 2 inches. The cutting zone offers a 5/8-inch length of cut with a 0.006-inch chamfer width at a 45-degree chamfer angle. Four right-hand helical flutes at a 30-degree helix angle provide efficient chip evacuation. An AlTiN (aluminum titanium nitride) PVD coating delivers heat resistance and surface hardness, making this tool well suited for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is center-cutting and rated for both roughing and finishing operations.

This end mill is built for precision milling tasks including shouldering, slotting, ramp-down milling, helical interpolation, drill milling, and plunging and recessing. It targets applications in steel, stainless steel, and cast iron as primary workpiece materials, with secondary capability in non-ferrous metals, superalloys, titanium, and hard materials. It belongs to the ISCAR ECCI-A-4 series, catalog number ECCI-A-4 188-625-C188, and is sold as a single-end tool in single-unit packaging. This tool is intended for use by machinists and CNC operators working in production or job-shop environments requiring tight chamfer geometry and reliable coating life.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating for high-temperature performance in ferrous and exotic alloy cutting
• 45-degree chamfer angle with 0.006-inch chamfer width for consistent edge break geometry
• Center-cutting design enables plunging, ramp-down, and helical interpolation without pre-drilling
• 30-degree medium helix with normal pitch supports both roughing and finishing passes
• Compatible with shouldering, slotting, drill milling, and recessing operations

Compatibility

Designed for use in standard 3/16-inch straight-shank ER or precision collet toolholders. Suitable for CNC machining centers and manual mills capable of accepting a 0.188-inch shank diameter. Primary workpiece materials include steel, stainless steel, and cast iron; secondary materials include non-ferrous metals, superalloys, titanium, and hard materials per ISCAR material codes P, M, K, N, S, and H.

Installation Notes

Install in a clean, properly sized collet or toolholder to the recommended gauge-line depth before tightening. Confirm runout with a dial indicator before first use, as excess runout accelerates corner and chamfer wear. Verify spindle speed and feed rate against the ISCAR IC900 grade cutting data for the specific workpiece material before engaging the cut. This tool should be handled and installed by qualified machinists familiar with CNC tooling setup procedures.
