Hertel 62852181 Roughing End Mill 1 in 5 Flute Tialn Cobalt

Product Description

The HERTEL 62852181 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel with a TiAlN coating, it handles elevated cutting temperatures while maintaining edge hardness. The 1-inch diameter cutting geometry features 5 spiral flutes in a coarse pitch configuration, which breaks chips into smaller segments and reduces cutting forces during heavy roughing passes. The 3/4-inch shank diameter provides solid tool-holder engagement. This end mill is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited for roughing operations in ferrous alloys, stainless steel, titanium, and hardened materials where heat resistance is critical. The TiAlN coating extends tool life in high-temperature, dry, or semi-dry cutting environments. The coarse pitch design clears chips efficiently during deep-depth-of-cut passes. With a 1-7/8-inch length of cut and 4-1/8-inch overall length, it fits standard tool holders for medium-reach applications on vertical mills and machining centers in both job shop and production environments.

Key Features

• M42 cobalt HSS construction for hardness retention at elevated cutting temperatures
• TiAlN coating improves wear resistance and performance in dry or semi-dry cutting
• 5-flute coarse pitch geometry promotes chip breaking and reduces cutting forces in heavy roughing
• Right-hand cut, right-hand spiral flute direction for standard spindle operation
• 1-7/8-inch length of cut with 3/4-inch shank for solid tool-holder engagement
• Non-centercutting design — requires a pre-drilled or pre-milled entry point

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill compatible with standard 3/4-inch end mill holders, collet chucks, and Weldon-style holders used on vertical milling machines and CNC machining centers.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before inserting or removing the end mill from its holder. Verify holder runout before commencing cuts, as excessive runout accelerates edge wear. This tool is non-centercutting and must not be plunged directly into solid material without a pre-existing entry point.
