Hertel 750410 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The HERTEL 750410 is a 4-flute, solid carbide square end mill designed for precision metal removal in milling operations. It carries a 5/16-inch cutting diameter with a 1/2-inch length of cut and a matching 5/16-inch shank diameter, keeping the tool compact and rigid in the spindle. The AlTiN coating extends tool life in dry and high-speed cutting environments by reducing heat buildup at the cutting edge. With a 30-degree helix angle and spiral flute geometry, it produces efficient chip evacuation and smooth surface finishes. Machinists and tool-and-die professionals use this stub-length configuration when rigidity and chatter resistance matter more than reach.

This end mill is suited for milling operations in ferrous and non-ferrous metals, including steel alloys, stainless steel, cast iron, and aluminum, depending on the cutting parameters and coolant strategy applied. The stub length of cut range of 0.5 to 0.6 inches makes it well-matched for shallow-to-medium pocket milling, slotting, and profiling on CNC machining centers and manual knee mills. Centercutting capability allows direct plunge entry without a pre-drilled start hole, reducing setup steps in production environments.

Key Features

• 4-flute solid carbide construction with micrograin substrate for hardness and edge retention
• AlTiN finish provides oxidation resistance and reduced friction at elevated cutting temperatures
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Stub length geometry increases rigidity and minimizes deflection in tight setups

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in standard ER collet chucks, shrink-fit holders, and set-screw end mill holders accepting a 5/16-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and locked before seating or removing the tool from the holder. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear on carbide tooling. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type before engaging the cut.
