Hertel E1031046 Square End Mill 23/32 in 4 Flute Hss

Product Description

The HERTEL E1031046 is a 4-flute, single-end square end mill manufactured from M7 high speed steel. It carries a 23/32-inch (0.7188 inches) cutting diameter with a 1-5/8-inch (1.625 inches) length of cut and a 3/4-inch (0.750 inches) shank diameter, giving a 3-7/8-inch overall length. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. This is an uncoated, regular-length tool intended for conventional milling operations on ferrous and non-ferrous materials. Machinists and tool-and-die professionals are the primary users.

This end mill fits standard milling applications in job shops, maintenance departments, and production environments. It is suited for side milling, slotting, and peripheral milling on manual or CNC vertical mills. The regular-length body keeps deflection low in general-purpose cuts. Note that this tool is non-centercutting, so it is not designed for direct plunge entry into solid material. Pre-drilled or ramped entry is required when pocket milling.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• 23/32-inch cutting diameter with 1-5/8-inch length of cut for standard depth applications
• 4-flute configuration balances chip clearance and surface finish
• 30-degree spiral helix angle promotes smooth chip evacuation
• Right-hand cut, right-hand flute — compatible with standard spindle rotation
• Uncoated finish suitable for re-sharpening and use with cutting fluids
• Non-centercutting design requires pre-drilled or ramped entry for plunge operations

Compatibility

Designed as a standard 3/4-inch shank end mill for use in collet chucks, end mill holders, and set-screw holders on vertical mills and machining centers that accept 3/4-inch straight shanks.

Installation Notes

Installation should be performed by a qualified machinist following standard machine tool setup procedures. Always power down and lock out the spindle before seating or removing the end mill from its holder. Ensure the shank is fully seated and the holder is torqued per the toolholder manufacturer's specifications. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when precision work is required.
