Hertel E8080024 Square End Mill 3/8 Inch 2 Flute Hss Tin

Product Description

The HERTEL E8080024 is a square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel and finished with a Titanium Nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS tooling. The cutter measures 0.375 inches in diameter with a 1.5-inch length of cut, a 0.375-inch shank diameter, and a 3.25-inch overall length. The 30-degree spiral flute geometry and two-flute configuration promote efficient chip evacuation. This end mill is suited for machinists and tool-and-die technicians working on CNC machining centers and manual mills.

This end mill is appropriate for light to medium milling work in shop and production environments. The centercutting design allows both peripheral and plunge cutting, making it versatile for slotting, profiling, and pocket milling operations. Right-hand cut and right-hand flute orientation match standard spindle rotation on most vertical mills and machining centers. The TiN finish is well-suited for use in steel, cast iron, aluminum, and similar workpiece materials at moderate cutting speeds.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general machining
• Titanium Nitride (TiN) coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix angle with spiral flute design promotes smooth chip flow
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute for standard spindle compatibility
• Two-flute configuration provides large chip gullets suitable for softer materials and slotting

Compatibility

Designed as a standard straight-shank square end mill compatible with ER collet chucks, end mill holders, and similar toolholding systems accepting a 0.375-inch shank diameter on vertical mills and CNC machining centers.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and tighten to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning cuts, as excessive runout will reduce tool life and surface finish quality.
