Hertel 750043 Square End Mill 7/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750043 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 7/16 inch cutting diameter, a 5/8 inch length of cut, and a 2-1/2 inch overall length, making it well suited for profiling, slotting, and peripheral milling. The four-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is uncoated, right-hand cut, and right-hand flute, with a spiral flute configuration. It is centercutting, which allows for direct plunging into a workpiece. Machinists and tool-and-die professionals are the primary users of this tool.

This end mill is intended for use in general-purpose milling on CNC machining centers and manual knee mills. The 7/16 inch shank diameter matches the cutting diameter, allowing it to seat directly in standard collets or end mill holders without a reducing sleeve. The uncoated solid carbide construction makes it a reliable choice for finishing passes on ferrous and non-ferrous metals where consistent dimensional accuracy is required. The 5/8 inch length of cut supports moderate-depth slotting and side milling operations in a shop or production environment.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding milling applications
• Four flutes with a 30-degree helix angle for efficient chip evacuation and surface finish quality
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand spiral flute configuration compatible with standard spindle rotation
• Uncoated finish suitable for applications where coating is not required or where regrinding is anticipated
• Matched shank and cutting diameter at 7/16 inch for straightforward toolholder setup

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 7/16 inch collets and end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists. Before installing or changing tooling, confirm the machine spindle is fully stopped and the control is in an e-stop or tool-change state. Seat the 7/16 inch shank fully into the collet or holder and torque the retention nut per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as solid carbide is brittle and sensitive to impact.
