Hertel 750440 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750440 is a 4-flute solid carbide square end mill designed for precision material removal in milling operations. With a 1/8 inch cutting diameter and a 1 inch length of cut, this single-end tool handles slotting, profiling, and finishing passes in ferrous and non-ferrous materials. The micrograin carbide construction provides the rigidity needed for tight-tolerance work, and the TiN coating reduces friction and extends tool life in production environments. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Installed by machinists and tool-and-die professionals, this end mill is a standard choice for CNC and manual milling applications requiring consistent edge geometry.

This end mill is suited for use on vertical mills, CNC machining centers, and similar machine tool setups where small-diameter precision cutting is required. The 1/8 inch shank diameter matches the cutting diameter, keeping the tool compact for tight-clearance work. Right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. Centercutting capability allows plunge entry directly into the workpiece. Typical applications include slot milling, contour milling, and pocket milling in aluminum, brass, steel, and similar machinable materials.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends cutting tool life
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end configuration with consistent square corner geometry

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/8 inch collets and tool holders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding systems and machine tool operation. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Seat the shank fully and evenly in the collet or end mill holder and torque the retention nut per the tool holder manufacturer specifications. Verify runout with an indicator before beginning a cutting operation.
