Hertel 72846561 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The HERTEL 72846561 is a single-end roughing end mill designed for high-efficiency material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, this tool handles tough ferrous and non-ferrous materials with extended tool life. It features a 1 inch mill diameter, 5 fine-pitch flutes, and a 2 inch length of cut. The TiN coating reduces friction and heat buildup at the cutting edge, making it well-suited for interrupted cuts and aggressive stock removal. This end mill is installed and operated by machinists and tooling professionals in production and job-shop environments.

This roughing end mill is intended for use in CNC machining centers and manual knee mills where rapid material removal is the primary objective. The fine-pitch, 5-flute configuration produces a smoother surface finish than coarse-pitch roughers while maintaining chip clearance under load. The right-hand cut and right-hand flute direction are standard for conventional and climb milling on vertical mills. Centercutting capability allows for direct plunge entry without a pre-drilled hole, adding flexibility in programming and setup.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• 5 fine-pitch flutes for aggressive roughing with improved surface finish
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand flute for standard milling operations
• Single-end configuration with 1 inch shank diameter matching the mill diameter

Compatibility

Designed as a standard 1 inch shank roughing end mill compatible with tool holders, collet chucks, and end mill holders sized for 1 inch shanks on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully powered down and locked out before loading or changing tooling. Secure the shank to the full recommended engagement depth in the tool holder to prevent pullout under cutting loads. Verify runout with a dial indicator after installation and before beginning a cut.
