Hertel E1030918 Square End Mill 1-5/8 in 2 Flute Hss

Product Description

The HERTEL E1030918 is a square end mill ground from M7 high speed steel, designed for general-purpose milling in ferrous and non-ferrous materials. It features a 1.625-inch cutting diameter, a 1.625-inch length of cut, and a 1.25-inch straight shank. The two-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The centercutting design allows both peripheral and plunge cuts. This tool is uncoated and ships in a single-end configuration, ready for use in manual knee mills, CNC vertical machining centers, and similar setups operated by machinists and tool-and-die professionals.

The E1030918 is suited for slotting, profiling, and light plunging operations on steel, aluminum, cast iron, and similar workpiece materials. Its regular-length geometry fits standard toolholders without extended-reach concerns, making it a practical choice for production shops, maintenance machining, and tool room work. The 1.25-inch shank diameter seats securely in R8, CAT, BT, or comparable toolholding systems sized for that bore. Right-hand flute direction matches conventional spindle rotation on standard vertical and horizontal mills.

Key Features

• M7 high speed steel construction provides good toughness and wear resistance for general milling applications
• 1.625-inch cutting diameter with 1.625-inch length of cut handles full-width slots and shoulder milling in a single pass
• 30-degree helix angle spiral flutes promote smooth chip flow and reduce cutting forces
• Centercutting geometry permits direct plunge entry without a pre-drilled pilot hole
• Two-flute design maximizes chip clearance, particularly useful in softer or gummy materials
• Uncoated finish maintains sharp edge geometry and simplifies resharpening

Compatibility

Designed as an OEM-style replacement or standard tooling option for vertical and horizontal milling machines accepting a 1.25-inch shank diameter end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Power down and lock out the spindle before inserting or removing the tool. Seat the shank fully into the collet or end mill holder and torque the retention hardware to the toolholder manufacturer's specification. Inspect the cutting edges and shank for damage before each use; do not operate a chipped or bent tool.
