Hertel E8050026 Square End Mill 13/32 in 2 Flute Hss Tin

Product Description

The HERTEL E8050026 is a double-end square end mill ground from M7 high speed steel and finished with a TiN (titanium nitride) coating. It measures 0.4063 inches (13/32 inch) in cutting diameter with a 13/16-inch length of cut and a 1/2-inch shank diameter, giving it a compact, rigid profile suited for close-tolerance milling work. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cutting passes. At 3-3/4 inches overall length and weighing 0.15 pounds, it fits standard milling machine and machining center toolholders without extension. The center-cutting design allows the tool to plunge directly into workpiece material.

This end mill is intended for general-purpose milling operations including slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. The double-end configuration doubles effective tool life before the part is retired, making it a practical choice for production environments and job shops where tooling cost per cut matters. Right-hand cut and right-hand flute orientation are standard for conventional milling setups. The TiN finish provides a moderate improvement in surface hardness and lubricity over uncoated HSS.

Key Features

• M7 high speed steel construction for toughness in interrupted and general milling cuts
• TiN coating improves surface hardness and extends tool life versus bare HSS
• Double-end design: two usable cutting ends per tool
• 30-degree helix angle with spiral flutes for efficient chip flow
• Center-cutting geometry allows direct plunge entry
• Right-hand cut, right-hand flute — compatible with standard milling setups

Compatibility

Designed for use in standard 1/2-inch milling machine collets, end mill holders, and Weldon-style toolholders. Suitable for machining centers, knee mills, and manual milling machines configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder and torque set screws or collet nuts to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut.
