Hertel E1050018 Square End Mill 9/32 in 2 Flute Hss

Product Description

The HERTEL E1050018 is a double-end square end mill designed for milling, slotting, and profiling operations in metal and ferrous materials. Manufactured from M7 high speed steel, this tool features a 9/32 inch (0.2813 inch) cutting diameter, a 9/16 inch (0.5625 inch) length of cut, and a 3/8 inch shank diameter. The 30-degree spiral helix and right-hand cut geometry promote efficient chip evacuation and smooth cutting action. With two flutes and center-cutting capability, this end mill handles both plunge and peripheral cutting. It is used by machinists and tool-and-die professionals in manual mills, CNC knee mills, and general-purpose machining centers.

This end mill suits light to medium material removal in steel, cast iron, and similar workpiece materials. The double-end configuration provides two usable cutting ends, extending service life between tool changes. The uncoated M7 HSS construction is appropriate for lower-speed operations and applications where regrinding is preferred over coated-tool replacement. The 3-1/8 inch overall length fits standard collet and end mill holder setups without excessive overhang in typical setups.

Key Features

• Center-cutting design allows direct plunge entry into the workpiece
• Double-end configuration yields two cutting ends per tool
• M7 high speed steel construction supports regrinding and lower-speed applications
• 30-degree helix angle promotes smooth chip flow and reduced chatter
• Right-hand cut and right-hand flute spiral for standard milling setups
• Uncoated finish suitable for applications where post-use regrinding is standard practice

Compatibility

Designed as a standard shank square end mill for use in collet chucks, end mill holders, or Weldon-style holders accepting a 3/8 inch shank diameter on manual or CNC milling machines.

Installation Notes

Installation and tool changes should be performed with the machine fully powered down and the spindle at rest. A licensed machinist or qualified shop technician should verify that the holder bore and collet size match the 3/8 inch shank before seating the tool. Ensure proper tool projection and tighten the holder to the machine manufacturer's specified torque using appropriate tooling keys. Inspect both cutting ends for chipping or wear before mounting.
