Hertel 750908 Square End Mill 3/32 in 4 Flute Carbide Tin

Product Description

The HERTEL 750908 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With a 3/32 inch (0.0938 inch) cutting diameter and a 3/8 inch length of cut, this single-end tool is well suited for tight-tolerance slotting, profiling, and peripheral milling in small-feature applications. The 4-flute, 30-degree right-hand helix geometry promotes efficient chip evacuation and smooth surface finishes. A Titanium Nitride (TiN) coating adds surface hardness and reduces friction, extending tool life in production environments. Machinists and CNC operators working in toolrooms and job shops will find this end mill sized for detailed work.

This end mill is intended for use in vertical machining centers, CNC mills, and manual milling machines where a small-diameter, short-cut tool is required. The 1/8 inch shank diameter fits standard collets and tool holders common in light-duty and precision machining setups. Its regular-length designation and 1-1/2 inch overall length make it a practical choice for shallow pocket milling, contouring, and finishing passes on ferrous and non-ferrous workpieces. Micrograin carbide substrate supports consistent performance at elevated cutting speeds.

Key Features

• 3/32 inch cutting diameter with 3/8 inch length of cut for small-feature precision work
• 4-flute, 30-degree right-hand helix for efficient chip evacuation and improved surface finish
• Solid micrograin carbide construction for rigidity and wear resistance
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• Centercutting design allows plunge entry into the workpiece
• 1/8 inch shank diameter fits standard collet sizes

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 1/8 inch shank collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and de-energized before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, and confirm feeds and speeds are appropriate for the workpiece material and coating type.
