Hertel 750428 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The HERTEL 750428 is a solid carbide square end mill designed for precision milling operations across a wide range of metals and engineered materials. It features a 3/4-inch cutting diameter, a 2-1/4-inch length of cut, and a 3-flute configuration that balances chip evacuation with surface finish quality. A 30-degree helix angle promotes smooth cutting action and reduces cutting forces. The TiN (Titanium Nitride) coating extends tool life by improving wear resistance and reducing friction at the cutting edge. This end mill is a single-end, right-hand cutting tool manufactured from micrograin carbide substrate, making it well-suited for demanding production environments.

This end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. It is appropriate for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 3/4-inch shank diameter fits standard ER collet chucks, end mill holders, and hydraulic toolholders commonly found in job shops and production facilities. It is installed by machinists and tool-and-die professionals working in manufacturing, maintenance, and fabrication settings.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends cutting edge life
• 3-flute design balances material removal rate with chip clearance
• 30-degree helix angle promotes smooth cutting and reduced cutting forces
• Center-cutting capable, allowing plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for milling applications requiring a 3/4-inch diameter, 3/4-inch shank, single-end solid carbide square end mill in ER, end mill holder, or hydraulic chuck tooling systems.

Installation Notes

Installation is performed by a qualified machinist or tooling specialist. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Torque the toolholder to the manufacturer specification for the holder type in use. Confirm runout with a dial indicator before beginning a cut, as excessive runout will accelerate edge wear and reduce surface finish quality.
