Cleveland C32998 Square End Mill 0.5 in 4 Flute Cobalt

Product Description

The CLEVELAND C32998 is a cobalt double-end square end mill designed for material removal in demanding machining applications. Built from M42 cobalt high-speed steel and finished with a TiCN coating, this tool delivers extended cutting life in abrasive and heat-generating operations. The 0.5-inch cutting diameter, 1-inch length of cut, and 4-flute spiral geometry support aggressive feed rates while maintaining surface finish quality. The 30-degree helix angle promotes efficient chip evacuation. This end mill is intended for use by machinists and tool-and-die professionals operating manual or CNC milling equipment.

The C32998 is suited for milling high-temperature alloys, stainless steel, and steel. Its centercutting capability allows plunge entry without a pre-drilled hole, making it practical for slotting, profiling, and pocket milling operations. The double-end design provides two usable cutting ends, extending tool service life before replacement. The straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw retention systems commonly found in production and job-shop environments.

Key Features

• M42 cobalt construction for heat resistance in high-temperature alloy and stainless steel applications
• TiCN coating reduces friction and extends cutting edge life
• Double-end design provides two cutting ends per tool
• Centercutting geometry allows direct plunge entry
• 30-degree helix angle promotes chip evacuation in spiral flute configuration
• Right-hand cut, right-hand flute with straight-cylindrical and Weldon flat shank

Compatibility

Designed for use in standard end mill holders accepting a 0.5-inch straight shank with Weldon flat. Primary workpiece materials include high-temperature alloys, stainless steel, and steel. Part of the Cleveland HDC-4C series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per applicable shop safety procedures. Ensure the Weldon flat is properly aligned with the set screw in the tool holder to prevent axial pullout under load. Verify runout with a dial indicator before production cuts. Consult machine tool documentation for appropriate spindle speed and feed rate ranges for the workpiece material.
