Hertel 62888821 Roughing End Mill 1/2 in 4 Flute Cobalt Tialn

Product Description

The HERTEL 62888821 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous machining operations. Built from M42 cobalt high-speed steel, it carries a TiAlN coating that extends tool life at elevated cutting temperatures. The 1/2 inch diameter, 4-flute configuration with a coarse pitch and right-hand spiral flute geometry delivers high chip clearance and reduced cutting forces. At 1 inch length of cut and 3 inches overall length, it fits standard toolholders on vertical and horizontal milling machines. This tool is installed and operated by machinists and tool-and-die professionals in production and job-shop environments.

This roughing end mill is suited for milling slots, pockets, and peripheral cuts where maximum stock removal is the priority over surface finish. The coarse pitch tooth geometry breaks chips aggressively, reducing heat buildup and chatter on deeper passes. Centercutting capability allows plunge entry directly into the workpiece. Typical applications include roughing passes on steel, stainless alloys, and other tough materials in both manual and CNC milling setups.

Key Features

• M42 cobalt construction for elevated heat resistance and tool hardness
• TiAlN coating reduces friction and extends tool life in high-temperature cuts
• Coarse pitch, 4-flute design promotes aggressive chip evacuation
• Centercutting capable, allowing direct plunge milling
• Right-hand cut and right-hand spiral flute for standard spindle compatibility
• Single-end configuration with 1/2 inch shank for standard collet and endmill holders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 1/2 inch endmill holders, collet chucks, and Weldon-style holders used on vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle drive before loading or unloading the tool. Ensure the shank is fully seated and the setscrew or collet nut is torqued per the toolholder manufacturer specification. Verify correct spindle rotation direction before engaging the cut, as this is a right-hand cut tool.
