Hertel 750681 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The HERTEL 750681 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/4 inch cutting diameter with a 2.25 inch length of cut, a matching 3/4 inch shank diameter, and a 5 inch overall length. The three-flute geometry and 30-degree helix angle support efficient chip evacuation and balanced cutting forces. An AlTiN coating improves heat resistance and tool life in abrasive and high-temperature cutting conditions. The micrograin carbide substrate provides the hardness and rigidity required for demanding cuts. This end mill is centercutting, allowing plunge entry into the workpiece.

This end mill is suited for milling ferrous and non-ferrous metals in job shop, production, and toolroom environments. The right-hand cut orientation and AlTiN finish make it well matched to dry or near-dry machining of hardened steels, stainless steels, cast iron, and similar materials. It is installed in CNC machining centers and manual mills by machinists and tool-and-die professionals. The 2.25 inch length of cut accommodates medium-depth pocketing, slotting, and profiling operations.

Key Features

• 3/4 inch cutting diameter with a 2.25 inch length of cut for medium-depth operations
• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut, single-end configuration for standard CNC and manual mill setups

Compatibility

Designed as a standard-shank solid carbide square end mill with a 3/4 inch shank diameter, compatible with ER, collet chuck, and end mill holder tooling systems that accept 3/4 inch shanks.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated in the holder and that set screws or collet nuts are torqued according to the toolholder specification. Verify runout with an indicator before beginning a cut to protect both the tool and the workpiece.
