Hertel 750490 Square End Mill 1/16 in 2 Flute Solid Carbide

Product Description

The HERTEL 750490 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.0625 inch (1/16 inch) cutting diameter and a 0.125 inch (1/8 inch) length of cut, this end mill is built for tight-tolerance work in small-feature applications. The two-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation, and the TiN (titanium nitride) finish improves surface hardness and wear resistance. The centercutting design allows for plunge entry directly into the workpiece. This tool is installed and used by machinists and CNC operators in job shops and production environments.

This end mill is suited for profiling, slotting, and plunge milling of ferrous and non-ferrous materials where fine detail and small-diameter cutting are required. The 0.125 inch shank diameter fits standard collets and tool holders designed for small-bore end mills. With a 1.5 inch overall length, the tool is compact and stiff, reducing deflection during light-duty cuts. Right-hand cut and right-hand spiral flute geometry make it compatible with conventional CNC machining center spindle rotation. Applications include die and mold work, prototype machining, and precision part manufacturing.

Key Features

• 0.0625 inch cutting diameter for small-feature and fine-detail milling
• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN finish increases surface hardness and extends tool life
• 30-degree helix angle with spiral flutes for effective chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut with right-hand spiral flute for standard CNC spindle compatibility

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 0.125 inch shank diameter; suitable for CNC machining centers and manual mills configured for right-hand rotation.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before beginning production cuts, particularly given the small diameter of this tool.
