Hertel E8053040 Square End Mill 5/8 in 4 Flute Hss Tin

Product Description

The HERTEL E8053040 is a square end mill designed for precision milling operations in ferrous and non-ferrous metals. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS tooling. The 5/8 inch diameter cutter features 4 flutes with a 30-degree right-hand helix and spiral flute geometry, producing efficient chip evacuation during slotting, profiling, and peripheral milling. With a 1-3/8 inch length of cut and 5 inch overall length, it suits a range of medium-depth milling applications. The centercutting design allows plunge entry directly into the workpiece.

This end mill is suited for use in manual knee mills, CNC machining centers, and bridgeport-style machines. It is appropriate for cutting aluminum, steel, cast iron, and similar materials in job shop, maintenance, and production environments. The 5/8 inch shank diameter is compatible with standard ER collets, end mill holders, and Weldon-style tool holders. Machinists, tool and die makers, and general machine shop technicians are the primary users of this tool.

Key Features

• M7 high speed steel construction for strength and toughness in interrupted cuts
• TiN coating reduces friction and extends tool life in steel and alloy applications
• 4-flute, 30-degree right-hand helix promotes smooth cutting action and chip flow
• Centercutting geometry allows direct plunge milling without pre-drilling
• Spiral flute type with right-hand cutting direction for standard climb and conventional milling
• No chipbreaker, variable helix, or extended reach — straightforward general-purpose geometry

Compatibility

Designed as a general-purpose square end mill for use in standard 5/8 inch end mill holders, ER collet chucks, and Weldon-style tool holders on manual and CNC milling machines.

Installation Notes

Installation is performed by machinists or machine tool operators. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify the shank is fully seated and the tool holder is torqued to the holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut to avoid premature tool wear or chatter.
