Hertel 750370 Square End Mill 3/4 in 2 Flute Carbide Altin

Product Description

The HERTEL 750370 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 3/4-inch cutting diameter and a 1-1/2-inch length of cut, this single-end tool is built for material removal in ferrous and non-ferrous applications where tool life and edge integrity are critical. The AlTiN coating provides oxidation resistance and allows operation at elevated cutting temperatures, extending tool life in hard or abrasive workpiece materials. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is installed and operated by machinists and CNC tooling professionals.

This end mill suits vertical machining centers, CNC mills, and manual knee mills requiring a 3/4-inch shank diameter and 4-inch overall length. It is suited for slotting, profiling, and peripheral milling in production and job-shop environments. The 2-flute configuration is particularly effective in applications where chip clearance is a priority, such as milling softer steels, aluminum alloys, or materials that generate larger chips. Right-hand cut and right-hand flute direction are standard for conventional spindle setups.

Key Features

• Solid carbide micrograin substrate for high hardness and wear resistance
• AlTiN coating for elevated-temperature oxidation resistance and extended tool life
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Center-cutting capability allows plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end design with 3/4-inch shank diameter for secure toolholder engagement

Compatibility

Designed for use in standard milling chucks, collet holders, and shrink-fit toolholders accepting a 3/4-inch shank diameter on CNC and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per shop lockout/tagout procedures. Ensure the toolholder bore and shank are clean and free of chips or burrs before seating the end mill. Proper runout should be verified with a dial indicator before cutting to avoid premature edge wear. Follow machine manufacturer torque specifications for drawbar or collet nut tightening.
