Hertel 750036 Square End Mill 9/64 in 4 Flute Solid Carbide

Product Description

The HERTEL 750036 is a solid carbide square end mill designed for precision milling in metal, composite, and plastic workpieces. It features a 9/64 inch (0.1406 inch) cutting diameter with four spiral flutes and a 30-degree helix angle, delivering efficient chip evacuation and smooth cutting action. The uncoated carbide construction provides rigidity and wear resistance suited to fine-detail work and tight-tolerance slots, pockets, and profile cuts. With a 9/16 inch length of cut and a 3/16 inch shank diameter, this end mill fits standard collets and tool holders in CNC machining centers and manual mills. Licensed machinists and tool-and-die technicians are the primary users of this tooling.

The 750036 is suited to light-to-medium material removal in ferrous and non-ferrous metals, engineering plastics, and composite materials. Its centercutting geometry allows plunge entry into a workpiece surface, making it practical for full-depth pocket milling without a pre-drilled entry hole. The compact 2 inch overall length and small diameter make it especially well-matched for fine detail work, prototype machining, and toolroom applications where precision and rigidity are critical. Right-hand cut and right-hand flute configuration is standard for conventional vertical spindle machines.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 9/64 inch cutting diameter (0.1406 inch) for fine detail and tight-tolerance work
• Four spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without a pilot hole
• Uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut, right-hand flute — compatible with standard vertical spindle setups

Compatibility

Designed as a standard square end mill for use in CNC machining centers, knee mills, and toolroom milling machines equipped with collets or end mill holders accepting a 3/16 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or tool holder to the recommended grip depth and torque the retention hardware per the machine tool manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and should not be used if the edge is compromised.
