Hertel E8030036 Square End Mill 9/16 in 2 Flute Hss Tin

Product Description

The HERTEL E8030036 is a 2-flute, single-end square end mill designed for general-purpose milling in high speed steel (HSS) grade M7. It carries a Titanium Nitride (TiN) coating that extends tool life by reducing friction and surface wear during cutting operations. The mill features a right-hand cut, right-hand spiral flute with a 30-degree helix angle, making it well-suited for slotting, profiling, and peripheral milling in a wide range of ferrous and non-ferrous materials. The centercutting geometry allows plunge entry directly into the workpiece. This tool is installed and operated by machinists and CNC programmers in job shop, toolroom, and production environments.

This end mill is built for use in vertical machining centers, knee mills, and manual milling machines where a 1/2-inch shank is required. The 9/16-inch cutting diameter and 1-1/8-inch length of cut make it a practical choice for shallow-to-medium depth slots and shoulder milling passes. Its M7 HSS construction provides adequate toughness for interrupted cuts and general toolroom work where carbide is not required. The TiN finish adds surface hardness and helps reduce built-up edge on softer steels and aluminum. No extended reach geometry is present, keeping the tool rigid in standard setups.

Key Features

• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• TiN (Titanium Nitride) coating reduces friction and increases surface hardness for longer tool life
• 30-degree helix angle promotes smooth chip evacuation in spiral flute configuration
• Right-hand cut and right-hand flute for standard spindle rotation setups
• M7 high speed steel construction provides toughness for interrupted and general-purpose cuts
• Single-end design with 2 flutes balances chip clearance and cutting edge strength

Compatibility

Designed as an OEM-style replacement or direct toolroom selection for milling machines and machining centers that accept a 1/2-inch straight shank end mill.

Installation Notes

Installation is performed by a machinist or CNC operator using an appropriate end mill holder, collet chuck, or milling chuck rated for the 1/2-inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Confirm runout at the cutting diameter is within acceptable tolerance before beginning any cut. Follow shop-floor speeds and feeds guidelines for M7 HSS tooling based on workpiece material.
