Hertel E107006402 Square End Mill 1 Inch 2 Flute Hss

Product Description

The HERTEL E107006402 is a square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from high speed steel (HSS) with no coating applied, this tool delivers reliable performance in conventional milling applications where carbide is not required. The cutter measures 1 inch in diameter with a 2-inch length of cut, a 1-inch shank diameter, and a 4.5-inch overall length. The 42-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of materials. Two flutes provide adequate chip clearance for heavier cuts or gummier materials where a higher flute count would restrict flow.

This end mill is suited for use in manual knee mills, CNC machining centers, and toolroom applications where HSS tooling is preferred or required. The centercutting geometry allows the tool to plunge directly into a workpiece, making it practical for slot milling and pocket entry without a pre-drilled pilot hole. Right-hand cut orientation is standard for conventional spindle rotation. It is commonly used by machinists, tool-and-die makers, and maintenance shops performing general profiling, slotting, and contouring work.

Key Features

• 1 inch cutting diameter with 2-inch length of cut for deep slot and pocket milling
• High speed steel construction — suitable for applications where HSS is specified over carbide
• 42-degree helix angle for improved chip flow and reduced cutting pressure
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut, standard rotation for conventional machining setups
• Uncoated finish — compatible with re-sharpening and reconditioning services

Compatibility

Designed as a standard 1-inch shank square end mill compatible with R8 collets, end mill holders, and other toolholding systems sized for 1-inch straight shanks on manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and locked out before mounting or removing the tool from the holder. Ensure the shank is seated to the full recommended engagement depth in the collet or end mill holder to prevent pullout under load. Verify runout with a dial indicator after mounting before beginning the cut, as excessive runout will accelerate wear on an HSS tool.
