Hertel E1033116 Square End Mill 1-1/4 in 2 Flute Hss

Product Description

The HERTEL E1033116 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel with a bright, uncoated finish, it delivers reliable cutting performance across a range of machining applications. The tool features a 1.25-inch mill diameter, a 3-inch length of cut, and a 7.25-inch overall length. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows the tool to plunge directly into workpiece material. This end mill is installed and operated by machinists and tool-and-die professionals working on manual or CNC milling equipment.

This end mill is suited for slotting, profiling, and peripheral milling operations in job shop, production machining, and toolroom environments. The 2-flute configuration provides adequate chip clearance for applications involving softer materials or deeper slots where chip packing is a concern. The 5-inch reach length makes it appropriate for setups requiring extended clearance between the spindle and the workpiece. The 1.25-inch shank diameter is sized for standard milling chucks, collets, or end mill holders commonly found on vertical knee mills and machining centers.

Key Features

• M7 high speed steel construction for durability in general-purpose milling
• Bright, uncoated finish suitable for use with cutting fluids on a broad range of materials
• 30-degree helix angle promotes smooth cutting and efficient chip removal
• Centercutting design allows direct plunge entry into workpiece material
• 2-flute geometry provides open chip clearance for slotting and softer material applications
• Extended reach of 5 inches accommodates deep-cavity and clearance-critical setups

Compatibility

Designed for use in standard milling chucks, collets, and end mill holders with a 1.25-inch bore, compatible with vertical knee mills, bed mills, and CNC machining centers accepting a 1-1/4-inch shank diameter tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before loading or unloading the tool. Secure the shank to the full recommended engagement depth in the tool holder to minimize deflection and vibration during cutting. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.
