Hertel E103301602 Square End Mill 1/4 in 2 Flute Hss

Product Description

The HERTEL E103301602 is a single-end square end mill designed for general-purpose milling operations in metalworking and machining environments. Built from M7 high speed steel with a bright, uncoated finish, it measures 1/4 inch in cutting diameter with a 1 inch length of cut and an overall length of 3.0625 inches. The 3/8 inch shank diameter provides solid tool holding in standard collets and chucks. With a 30-degree helix angle and two right-hand spiral flutes, this end mill handles slotting, profiling, and peripheral milling on a wide range of workpiece materials. It is centercutting, allowing plunge entry directly into the workpiece. Machinists and toolroom operators are the primary users.

This end mill is suited for ferrous and non-ferrous metal cutting in manual mills, CNC machining centers, and knee mills. Typical applications include slotting, side milling, and light profiling passes in steel, aluminum, brass, and similar materials. The bright, uncoated finish makes it a practical choice for aluminum and non-ferrous applications where coating adhesion can be a concern. The 2-flute configuration provides good chip clearance in softer materials and slotting work. This is a single-end tool sold individually.

Installation Notes

End mills are installed and changed by machinists or toolroom personnel. Always power down and lock out the machine spindle before changing tooling. Ensure the shank is fully seated and the collet or holder is torqued to the machine manufacturer's specification. Inspect the cutting edges for chipping or wear before each use and do not exceed the recommended depth of cut for the material being machined.
