Hertel 84511948 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The HERTEL 84511948 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it carries a TiCN (titanium carbonitride) coating that increases surface hardness and wear resistance compared to uncoated tooling. The 1-inch cutting diameter and 5-flute geometry produce a coarse chip-breaking pattern that reduces cutting forces and heat buildup during heavy roughing passes. This tool is intended for use in CNC machining centers and manual mills by machinists and tool-and-die professionals who need reliable metal removal rates on ferrous and non-ferrous workpiece materials.

This end mill is suited for roughing operations in job shops, production machining environments, and maintenance repair operations. The right-hand cut and right-hand flute direction match standard spindle configurations. The 3/4-inch shank diameter fits standard collet chucks, end mill holders, and Weldon-style holders common across most vertical and horizontal milling setups. The non-centercutting design means it is intended for peripheral and side milling, not for plunge cuts directly into solid material.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• TiCN coating for increased surface hardness and extended tool life
• 5-flute roughing geometry reduces cutting forces and controls chip load
• Single-end design with right-hand cut and right-hand flute direction
• Non-centercutting — suited for side milling and peripheral roughing passes
• 3/4-inch shank fits standard collet chucks and end mill holders

Compatibility

Designed as an OEM-style roughing end mill for use in standard milling machines and machining centers accepting a 3/4-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder torque procedures and runout inspection. Power down and lock out the spindle drive before inserting or removing the tool from its holder. Inspect the shank and collet bore for chips or contamination before seating the tool. Verify runout at the cutting diameter with a dial indicator before beginning a roughing program, as excessive runout accelerates flute wear and can damage the workpiece.
