Hertel E1043964 Square End Mill 1 in 3 Flute Hss

Product Description

The HERTEL E1043964 is a single-end square end mill manufactured from M7 high speed steel. Designed for general-purpose milling operations, it features a 1-inch cutting diameter, a 1-7/8-inch length of cut, and a 3/4-inch straight shank. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action across a range of ferrous and non-ferrous materials. The uncoated HSS construction offers reliable toughness in light-to-moderate cutting applications. Machinists and toolroom operators select this geometry for slotting, profiling, and peripheral milling on manual mills and CNC machining centers alike.

This end mill suits standard production and toolroom environments where a regular-length, centercutting tool is needed for slotting or pocket milling. The centercutting design allows direct plunge entry into workpiece material without a pre-drilled starting hole. Right-hand cut and right-hand flute configuration matches conventional spindle rotation on vertical mills and machining centers. It is appropriate for use in job shops, maintenance departments, and production facilities requiring a dependable HSS end mill in a 1-inch diameter class.

Key Features

• 1-inch cutting diameter with 1-7/8-inch length of cut for rigid, accurate material removal
• M7 high speed steel construction provides toughness in interrupted cuts and general-purpose milling
• Three spiral flutes at 30-degree helix angle support efficient chip flow and reduced heat buildup
• Centercutting geometry enables direct plunge milling without a pilot hole
• Right-hand cut, right-hand flute — fits standard vertical mill and CNC machining center spindles
• Uncoated finish suitable for re-sharpening and compatible with cutting fluids or dry cutting

Compatibility

Designed as a standard single-end square end mill for use in milling chucks, collet holders, and end mill holders accepting a 3/4-inch straight shank, suitable for vertical mills and CNC machining centers.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with proper tool holding and speeds-and-feeds selection for HSS end mills. Secure the 3/4-inch shank fully in a clean, undamaged collet or end mill holder before operation, and verify runout with an indicator before cutting. Always power down and lock out the machine spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for maximum spindle speeds and depth-of-cut limits.
