Hertel E8030064 Square End Mill 1 in 2 Flute Hss Tin

Product Description

The HERTEL E8030064 is a single-end, square-profile end mill designed for milling operations in steel, cast iron, and similar ferrous and non-ferrous materials. It is manufactured from M7 high speed steel and carries a titanium nitride (TiN) coating that extends tool life by increasing surface hardness and reducing friction at the cutting edge. The cutter measures 1 inch in diameter with a 1-5/8 inch length of cut and a matching 1-inch straight shank. With 2 spiral flutes at a 30-degree helix angle, this tool balances chip evacuation with cutting stability. It is a center-cutting design, allowing plunge entry as well as conventional peripheral milling.

This end mill suits general-purpose milling applications in job shops, maintenance environments, and production settings. The 1-inch diameter and 4-1/8 inch overall length make it a practical choice for slot milling, profiling, and shoulder work on vertical machining centers and manual knee mills. Right-hand cut and right-hand flute geometry follow standard convention for most spindle configurations. The M7 material grade offers good toughness for interrupted cuts and general steel machining without the brittleness associated with carbide tooling.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose milling
• TiN coating increases surface hardness and extends tool life versus uncoated HSS
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• 30-degree spiral helix promotes efficient chip evacuation and smooth cutting action
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• 1-inch shank diameter suits standard ER or end mill holders in most machining setups

Compatibility

Designed as a standard-shank square end mill for use in end mill holders, collet chucks, or Weldon-style holders accepting a 1-inch shank diameter on vertical machining centers or manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out before changing tooling. Ensure the holder bore and shank are clean and free of chips or burrs before seating the tool. Confirm runout with a dial indicator after clamping, as excessive runout accelerates flute wear and degrades surface finish. Follow the machine manufacturer's torque procedure for the clamping fasteners on the end mill holder.
