Hertel E107003202 Square End Mill 0.5in 2 Flute Hss

Product Description

The HERTEL E107003202 is a 2-flute square end mill machined from M7 high speed steel, designed for general-purpose milling operations in ferrous and non-ferrous materials. It features a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 0.5 inch straight shank with a 3.25 inch overall length. The 42-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a right-hand cut, right-hand flute configuration with a spiral flute geometry and a centercutting tip, allowing it to plunge directly into workpiece material. It ships uncoated and is suited for shops running standard HSS-compatible speeds and feeds.

This end mill is used in manual mills, CNC machining centers, and knee mills across job shops, maintenance facilities, and production environments. The regular-length profile and 0.5 inch shank make it compatible with standard ER collet chucks, end mill holders, and Weldon-style tool holders commonly found in both light and medium-duty machining setups. It handles slotting, profiling, and plunge cuts in mild steel, aluminum, brass, and similar machinable materials.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general milling
• 42-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute spiral geometry for conventional milling setups
• Uncoated finish suitable for use with standard cutting fluids and lubricants
• Regular-length profile fits standard tool holders with 0.5 inch bore

Compatibility

Designed as a standard 0.5 inch shank square end mill compatible with ER collet chucks, end mill holders, and Weldon-style tool holders accepting a 0.5 inch shank diameter.

Installation Notes

Installation and use of end mills should be performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm tool holder runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates tool wear and reduces surface finish quality. Always follow the machine manufacturer and tooling manufacturer guidelines for speed, feed, and depth-of-cut recommendations appropriate to the workpiece material.
