Hertel E1051032 Square End Mill 0.5 in 4 Flute Hss

Product Description

The HERTEL E1051032 is a double-end, square-profile end mill designed for milling operations in ferrous and non-ferrous metals. Built from M7 high speed steel with a bright, uncoated finish, it features a 0.5 inch cutting diameter, 1 inch length of cut, and a 30-degree right-hand helix. The double-end design provides two usable cutting ends, extending tool life between changes. With four spiral flutes and a right-hand cutting direction, this tool is suited for face milling, slotting, and peripheral milling on manual and CNC machining centers. Total weight is 0.2 pounds.

This end mill is appropriate for job shop, production, and maintenance machining environments where a general-purpose HSS tool is preferred over carbide. The 0.5 inch shank diameter mounts directly in standard collet chucks, end mill holders, or Weldon-style tool holders. Regular length geometry keeps the tool rigid in shallow-to-moderate depth cuts. M7 grade HSS offers good toughness and wear resistance across a broad range of steels and aluminum alloys. It is installed and changed by machinists, tool-and-die makers, and maintenance technicians.

Key Features

• Double-end design provides two cutting ends per tool, reducing per-edge tooling cost
• M7 high speed steel construction for toughness in interrupted cuts and general-purpose milling
• 30-degree right-hand helix promotes smooth chip evacuation and reduced cutting forces
• Four spiral flutes for balanced surface finish and feed rate capability
• Bright, uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Regular length geometry maximizes rigidity at 4.125 inches overall length

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 0.5 inch collet chucks, end mill holders, and Weldon-style holders used on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation is performed by machinists or toolroom technicians. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the tool holder and torque the set screw or collet nut per the holder manufacturer specification. Confirm tool runout with a dial indicator before beginning a cut, as excessive runout accelerates wear and degrades surface finish on HSS tooling.
