Kennametal 5824189 Corner Chamfer End Mill 12mm 4 Flute

Product Description

The KENNAMETAL 5824189 is a solid carbide corner chamfer end mill designed for high-performance material removal in demanding machining environments. Built on the 4CH series platform, it features a 12.00 mm cutting diameter, a 25.98 mm length of cut, and four right-hand helical flutes with a 30-degree helix angle. The tool carries a TiN/TiAlN PVD coating, which extends wear resistance and thermal performance during both roughing and finishing operations. At 82.98 mm overall length with a 12.00 mm straight-cylindrical shank, this centercutting end mill is suited for machinists who need a single tool capable of multiple operation types without tool changes.

This end mill is rated for use on steel, stainless steel, cast iron, and non-ferrous metals, covering ISO material groups P, M, K, and N. The 0.30 mm chamfer width at a 45-degree chamfer angle makes it appropriate for edge-breaking and corner protection on precision components. Supported operations include shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. It is a single-end tool with normal pitch and no chipbreaker, making it well suited for general-purpose CNC machining centers in job shop and production environments. The material grade is KC633M. Manufacturers catalog number is 4CH1200DL026A.

Key Features

• Solid carbide construction in material grade KC633M for rigidity and wear life
• TiN/TiAlN PVD coating for thermal resistance and extended tool life on ferrous and non-ferrous materials
• 0.30 mm chamfer width at 45 degrees for consistent edge-breaking and corner chamfering
• Centercutting design supports plunging, helical interpolation, and drill milling operations
• Four right-hand helical flutes at 30-degree helix angle for balanced chip evacuation during roughing and finishing
• Straight-cylindrical 12.00 mm shank with tight tolerance for secure collet or end mill holder retention

Compatibility

Designed as an OEM-style solid carbide end mill replacement for CNC machining applications requiring a 12.00 mm diameter corner chamfer geometry in the KENNAMETAL 4CH series.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Secure the 12.00 mm shank in a properly sized collet, shrink-fit holder, or end mill holder before operation; verify runout is within acceptable limits for the application. Power down and lock out the spindle before any tool change. Confirm the machine tool is programmed with speeds and feeds appropriate for the workpiece material group and the KC633M carbide grade.
