Hertel E8053030 Square End Mill 15/32 in 4 Flute Hss

Product Description

The HERTEL E8053030 is a double-end, four-flute square end mill designed for general-purpose milling operations in machine shop and production environments. Manufactured from M7 high speed steel with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 15/32 inch (0.4688 inch) cutting diameter pairs with a 30-degree spiral helix and right-hand cut, right-hand flute geometry. Centercutting capability allows plunge entry into workpiece material without a pre-drilled hole. This tool is installed and run by machinists and CNC operators on vertical mills, knee mills, and machining centers.

The E8053030 suits ferrous and non-ferrous material removal in both manual and CNC milling applications. The double-end configuration extends tool life by providing two usable cutting ends. The 1 inch length of cut (LOC) is appropriate for shallow-to-moderate depth slotting, profiling, and peripheral milling passes. A 1/2 inch shank diameter provides a standard collet or end mill holder fit common across most milling setups. The TiN coating reduces friction and extends tool life in steels, cast iron, aluminum, and plastics at appropriate cutting parameters.

Key Features

• Double-end design provides two cutting ends, extending overall tool service life
• M7 high speed steel construction for toughness in interrupted and general milling cuts
• TiN finish increases surface hardness and reduces built-up edge in ferrous materials
• 30-degree helix spiral flute promotes efficient chip evacuation
• Centercutting geometry enables direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute for standard spindle direction use

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 1/2 inch shank end mill holder or collet chuck.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the holder. Seat the shank fully into a properly sized collet or end mill holder and torque the retention fastener per the holder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts.
