Hertel 750686 Square End Mill 9/32 in 2 Flute Carbide

Product Description

The HERTEL 750686 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastics. With a 9/32-inch (0.2813-inch) cutting diameter and a 3/4-inch length of cut, this tool delivers accurate shoulder milling, slotting, and profiling in CNC and manual machining setups. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cutting. Two flutes provide a balance of chip clearance and rigidity suitable for a wide range of work materials. The uncoated solid carbide construction offers consistent cutting edge sharpness straight out of the box.

This end mill is suited for use in job shops, tool rooms, and production machining environments. It is a single-end, centercutting design, allowing plunge entry directly into the workpiece when required. The right-hand cutting direction is standard for conventional CNC machining centers and knee mills. With a 5/16-inch shank diameter and a 2-1/2-inch overall length, it fits standard collets and tool holders commonly found in light-to-medium-duty milling setups. It is appropriate for machinists, tool and die makers, and CNC operators working on precision part features.

Key Features

• Solid carbide construction for rigidity and long cutting life
• 9/32-inch (0.2813-inch) cutting diameter for tight-tolerance features
• 30-degree helix angle promotes smooth cutting and efficient chip flow
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand spiral flute, two-flute configuration for chip clearance in slotting applications
• Uncoated finish suitable for use with cutting fluids on a broad range of materials

Compatibility

Designed as a standard-shank solid carbide square end mill compatible with 5/16-inch collets, ER collet chucks, and side-lock tool holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet nut is torqued to the tool holder manufacturer's specification before operation. Inspect the cutting edges for chips or damage before each use, and confirm workpiece fixturing is secure prior to cutting.
