Hertel 750498 Square End Mill 15/64 in 4 Flute Solid Carbide

Product Description

The HERTEL 750498 is a solid carbide square end mill designed for precise milling operations in metal, composite, and engineering plastic workpieces. The cutting diameter measures 15/64 inches (0.2344 inches decimal), with a 3/4-inch length of cut and a 1/4-inch shank diameter. Overall length is 2-1/2 inches. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and stable cutting action. The uncoated solid carbide construction delivers consistent edge integrity on a variety of work materials. Centercutting geometry allows plunge entry without a pre-drilled pilot hole. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

The HERTEL 750498 suits general-purpose milling tasks including slotting, profiling, and peripheral milling. It is well suited for use on manual knee mills and CNC machining centers. The 1/4-inch shank fits standard ER collets, end mill holders, and set-screw tool holders commonly found on both vertical and horizontal spindle machines. The 0.7000-to-0.8000-inch length-of-cut range provides flexibility for shallow-to-mid-depth passes. Single-end configuration means the tool is used from one end only.

Key Features

• 15/64-inch (0.2344-inch) cutting diameter for precise small-bore milling
• Solid carbide construction for rigidity and wear resistance
• 4-flute spiral geometry with 30-degree helix angle for efficient chip flow
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute for standard spindle rotation
• Uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for 1/4-inch shank tooling systems on standard CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully de-energized and locked out before inserting or removing the end mill from its holder. Seat the shank to the minimum engagement depth recommended for the holder type to prevent pull-out under load. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
