Hertel 75987594 Roughing End Mill 2 in Cobalt Ticn

Product Description

The HERTEL 75987594 is a single-end roughing end mill designed for heavy material removal in demanding milling applications. Built from M42 cobalt high-speed steel, it delivers hardness and heat resistance suited for cutting tough ferrous and non-ferrous materials. The 2-inch diameter tool features 8 coarse-pitch flutes with a TiCN coating, which reduces friction and extends tool life in high-feed roughing passes. With an 8-inch length of cut and an 11.75-inch overall length, this tool is configured for deep-reach roughing operations. It is right-hand cut with right-hand flute direction and is not center-cutting.

This roughing end mill is used in CNC machining centers and manual knee mills where aggressive stock removal is the priority. The coarse pitch flute geometry breaks chips efficiently and reduces chatter during heavy cuts. At 2 inches in diameter with a matching 2-inch shank, it is suited for large-bore toolholders in production and job-shop environments. Machinists and tool-and-die professionals working with steel alloys, stainless, and similar materials will find this tool appropriate for roughing passes before finishing operations.

Key Features

• M42 cobalt HSS construction for elevated red hardness and wear resistance
• TiCN coating reduces friction and improves tool life in ferrous materials
• 8 coarse-pitch flutes for aggressive chip evacuation during roughing
• 2-inch diameter with 2-inch shank for rigid, high-torque toolholder fit
• 8-inch length of cut enables deep-reach roughing passes
• Right-hand cut and right-hand flute direction, single-end configuration

Compatibility

Designed for use in standard 2-inch bore toolholders on CNC machining centers and manual milling machines that accept large-shank roughing end mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before loading or unloading the tool. Use a calibrated torque wrench and appropriate collet or end mill holder rated for the 2-inch shank diameter. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear on a roughing tool of this size.
