Hertel E1043036 Square End Mill 9/16 Inch 3 Flute Hss

Product Description

The HERTEL E1043036 is a single-end, square-profile end mill designed for general-purpose milling operations in metal and ferrous materials. Manufactured from M7 high speed steel in an uncoated finish, it features a 9/16 inch cutting diameter, a 1-3/8 inch length of cut, and a 1/2 inch shank diameter. The three-flute spiral geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. The centercutting design allows plunge entry as well as conventional peripheral milling. Overall length is 3-3/8 inches. This tool is installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited for light to medium material removal on steel, cast iron, and similar ferrous workpieces in job shop and production environments. Its three-flute configuration balances chip evacuation with surface finish, making it appropriate for slotting, profiling, and shoulder milling operations. The uncoated M7 HSS construction allows for easy resharpening, a practical advantage in lower-volume shops where regrinding is standard practice. No extended reach is featured, keeping the tool stiff for reduced deflection in typical depth-of-cut applications.

Key Features

• M7 high speed steel construction for durability and resharpenability
• Three spiral flutes at 30-degree helix angle for balanced chip flow and cut quality
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute for standard spindle rotation on most mills
• Uncoated finish compatible with cutting fluid use and regrinding services
• 1/2 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for manual knee mills and CNC machining centers accepting a 1/2 inch shank end mill holder or collet.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before loading or changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware per the machine tool manufacturer specifications. Verify runout with a dial indicator before beginning a cut, and confirm that spindle speed and feed rate are appropriate for the workpiece material and depth of cut.
