Hertel E1051036 Square End Mill 9/16 in 4 Flute Hss

Product Description

The HERTEL E1051036 is a double-end, 4-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Ground from M7 high speed steel, it delivers consistent cutting performance without a coating. The cutter features a 30-degree right-hand spiral flute with right-hand cut direction. At 9/16 inch in diameter with a 5/8 inch shank, this tool fits standard milling chucks and collets. The regular-length geometry and 1-3/8 inch length of cut suit slot milling, peripheral milling, and step machining on manual mills and CNC machining centers. This is a production-grade tool for machinists and toolroom operators.

This end mill is intended for use in light-to-medium metal removal applications where an uncoated HSS tool is preferred over carbide. The double-end design allows the operator to flip to the second cutting end when the first shows wear, extending usable tool life per unit. It is suited for milling mild steel, alloy steel, aluminum, and similar materials in both shop and production environments. The 5 inch overall length gives sufficient clearance for most standard setups without requiring extended-reach tooling.

Key Features

• M7 high speed steel construction for toughness in interrupted and general milling cuts
• Double-end design provides two cutting ends per tool
• 30-degree right-hand spiral flute for efficient chip evacuation
• Uncoated finish suitable for applications where re-sharpening is required
• Non-centercutting geometry — not intended for direct plunge operations
• Regular length profile with 1-3/8 inch length of cut for standard slot and peripheral work

Compatibility

Designed as an OEM-style replacement or stock tooling option for standard milling setups accepting a 5/8 inch shank diameter end mill.

Installation Notes

Installation is performed by a machinist or toolroom technician using a standard end mill holder, collet chuck, or Weldon-style holder sized for a 5/8 inch shank. Confirm the spindle is fully stopped and the machine is in an energy-isolated state before loading or unloading the tool. This tool is non-centercutting and should not be used for direct axial plunge operations without a pre-drilled entry point. Inspect the cutting edges and shank for wear or damage before each use.
