Hertel 750619 Solid Carbide Square End Mill 3 Flute

Product Description

The HERTEL 750619 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining applications. This single-end tool features a 3/32-inch cutting diameter, a 3/8-inch length of cut, and a 1/8-inch shank diameter, giving it a compact profile suited for fine detail work and tight-tolerance slots or pockets. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life when cutting ferrous and hardened materials. With a 30-degree helix angle and 3 flutes, the tool balances chip evacuation with surface finish quality. Overall length is 1-1/2 inches. A licensed machinist or tool-and-die technician is the typical end user.

This end mill is suited for CNC vertical machining centers and manual mills where small-diameter, high-precision cuts are required. The centercutting geometry allows both plunge and ramping entry, expanding its versatility in contouring and slotting operations. Right-hand cut orientation is standard for conventional spindle rotation. Applications include mold and die work, aerospace component finishing, and general precision part production in steel, stainless, cast iron, and similar materials where AlTiN coating performance is an advantage.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat tolerance and extended tool life
• Centercutting design allows direct plunge entry without a pre-drilled hole
• 30-degree helix angle balances chip flow and surface finish
• 3-flute geometry for efficient material removal at small diameters
• Right-hand cut for use with standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 1/8-inch collets and tool holders on CNC and manual milling machines accepting right-hand single-end tooling.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use.
