Hertel E1030901 Square End Mill 1/2 in 2 Flute Hss

Product Description

The HERTEL E1030901 is a square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M7 high speed steel, this single-end, uncoated tool features a 1/2 inch cutting diameter, a 13/16 inch length of cut, and a 3/8 inch shank diameter with an overall length of 2-1/2 inches. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. With two flutes and a centercutting design, this end mill handles slotting, profiling, and plunge-entry cuts in a single setup.

This end mill is suited for use in manual mills, knee mills, and CNC machining centers where moderate material removal and close-tolerance finishing are required. Right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations. The M7 HSS grade provides good toughness and wear resistance for cutting mild steels, aluminum, brass, and similar materials at conventional speeds without coolant coating requirements.

Key Features

• 1/2 inch cutting diameter with 13/16 inch length of cut for slotting and profiling
• M7 high speed steel construction for toughness in a range of workpiece materials
• 30-degree helix angle promotes smooth chip flow and reduced cutting pressure
• Centercutting capability allows direct plunge entry into workpiece material
• Two-flute design maximizes chip clearance in softer materials and slot milling
• Uncoated finish suitable for use with cutting fluids on conventional machining setups

Compatibility

Designed as a standard-shank replacement or service end mill for manual and CNC milling machines accepting a 3/8 inch straight shank collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and the tool holder or collet is clean and free of debris before seating the shank. Tighten the collet or set screw to the tool holder manufacturer's specification using appropriate wrenches. Verify runout with a dial indicator before beginning a production cut.
