Hertel 750401 Square End Mill 5/16 Inch 2 Flute Solid Carbide

Product Description

The HERTEL 750401 is a 2-flute solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous metals. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles elevated cutting temperatures while maintaining edge integrity. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. At 5/16 inch in diameter with a 13/16 inch length of cut, this tool is suited for slotting, profiling, and peripheral milling in tight-tolerance applications. Licensed machinists and toolroom operators are the primary users.

This end mill is configured as a single-end, center-cutting tool with a right-hand cut and right-hand helix. The center-cutting geometry allows direct plunge entry into the workpiece without pre-drilling. It is well suited for CNC machining centers and manual knee mills running ferrous alloys, stainless steel, hardened steels, and cast iron where coating durability is required. The 5/16 inch shank diameter matches standard collet and end mill holder sizes common across most machine tool setups.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• AlTiN coating extends tool life at elevated cutting temperatures
• 30-degree helix angle promotes efficient chip flow and reduces deflection
• Center-cutting design allows direct plunge milling without a pilot hole
• Right-hand cut configuration compatible with standard spindle rotation
• 2-flute geometry provides chip clearance in slotting and full-width cuts

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16 inch straight shank in collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and power is off before loading or removing tooling. Seat the shank to the recommended depth in the collet or holder and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
