Hertel E803010803 Square End Mill 1-1/8 in 2 Flute Hss Tin

Product Description

The HERTEL E803010803 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel with a titanium nitride (TiN) finish, it carries a 1.125-inch cutting diameter and a 1.5-inch length of cut. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction promote efficient chip evacuation and stable tool engagement. Centercutting capability allows plunge entry directly into the workpiece. This tool is sized for use in standard milling machines, knee mills, and CNC machining centers and is typically installed by machinists and toolroom technicians.

This end mill suits a wide range of milling applications including slotting, profiling, and peripheral milling in shop and production environments. The 0.75-inch shank diameter fits standard R8, CAT, BT, and direct-mount toolholders common in vertical and horizontal milling setups. With a 3.875-inch overall length and 2-flute configuration, it is well suited for applications requiring a balance of chip clearance and core strength, particularly in softer steels, aluminum alloys, and plastics.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general milling
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix spiral flute promotes smooth cutting action and effective chip removal
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute direction for use in standard spindle rotation
• 2-flute geometry maximizes chip clearance in softer or gummy materials

Compatibility

Designed as a direct-fit replacement end mill for standard 0.75-inch shank toolholders used in vertical knee mills, manual milling machines, and CNC machining centers requiring a 1.125-inch diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued according to the toolholder manufacturer specification. Inspect the cutting edges for chips or wear before use and confirm proper tool runout with a dial indicator when precision work is required.
