Hertel 750514 Square End Mill 15/32 in 4 Flute Carbide

Product Description

The HERTEL 750514 is a solid carbide square end mill engineered for precision milling in demanding machining environments. With a 15/32-inch (0.4688-inch decimal) cutting diameter and a 1-inch length of cut, it delivers consistent performance in slotting, profiling, and peripheral milling operations. The four-flute, right-hand spiral geometry combined with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention needed for ferrous and non-ferrous materials. The bright, uncoated finish makes this tool suitable for applications where coating-free contact is preferred.

This end mill is designed for use in CNC machining centers and manual knee mills where high-accuracy material removal is required. The 1/2-inch shank diameter fits standard collet chucks and end mill holders common in production and job-shop environments. The centercutting design allows plunge entry directly into the workpiece, expanding its versatility for pocketing and ramping operations. Typical applications include milling aluminum, brass, mild steel, and similar materials in both prototype and production runs.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• Four-flute, right-hand spiral design promotes efficient chip clearance
• 30-degree helix angle reduces cutting forces and improves surface finish
• Centercutting capability allows direct plunge entry into workpiece
• Bright, uncoated finish suitable for coating-sensitive applications
• 3-inch overall length with 1/2-inch shank for rigid tool holding

Compatibility

Designed for use in standard 1/2-inch collet chucks and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician. Power down and lockout the spindle before mounting or removing the tool. Ensure the shank is fully seated and the collet or holder is torqued to the machine manufacturer's specification. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
