Hertel E103104801 Square End Mill 3/4 in 4 Flute Hss

Product Description

The HERTEL E103104801 is a 4-flute, square-end, single-end mill manufactured from M7 high speed steel. It carries a 3/4 inch cutting diameter with a 1-5/8 inch length of cut and a 3-3/4 inch overall length. The 3/4 inch shank diameter matches the cutting diameter for straightforward tool-holder setup. The spiral flute geometry runs at a 30-degree helix angle with a right-hand cut and right-hand flute orientation. This tool is uncoated and suited for general-purpose milling in ferrous and non-ferrous materials where HSS tooling is specified. Machinists and tool-room operators working on manual or CNC mills are the primary users.

This end mill is appropriate for slotting, profiling, and peripheral milling operations in job-shop, maintenance, and production environments. The 1-5/8 inch length of cut falls within the 1.5 to 2.0 inch length-of-cut range for this tool class, giving adequate reach for moderate-depth passes. It is not a centercutting design, so plunge cuts are not a recommended application. Best practice is to use it for side milling and conventional slotting where the square end geometry produces a clean, flat-bottomed feature.

Key Features

• 3/4 inch cutting diameter with matching 3/4 inch shank diameter for direct collet or end-mill-holder mounting
• M7 high speed steel construction for durability in general-purpose milling applications
• 4-flute configuration balances chip clearance and surface finish in most ferrous materials
• 30-degree helix angle spiral flute promotes smooth cutting action and efficient chip evacuation
• Right-hand cut, right-hand flute — standard orientation for conventional mill spindles
• Uncoated finish allows easy resharpening by a qualified tool grinder

Compatibility

Designed as a standard 3/4 inch shank square end mill compatible with collet chucks, side-lock holders, and hydraulic tool holders sized for 3/4 inch shank tooling on vertical or horizontal milling machines. Not a centercutting tool; confirm application requirements before use.

Installation Notes

Installation is performed by a machinist or tool-room technician. Secure the shank fully within the tool holder to the minimum engagement depth recommended by the holder manufacturer before tightening. Confirm spindle rotation direction matches the right-hand cut orientation of this tool before starting the machine. Inspect the tool and holder for runout with a dial indicator after setup to maintain dimensional accuracy and tool life.
