Hertel E107002001 Square End Mill 5/16 in 2 Flute Hss

Product Description

The HERTEL E107002001 is a 2-flute square end mill designed for general-purpose milling operations in a wide range of ferrous and non-ferrous materials. Manufactured from M7 high speed steel, this uncoated tool features a spiral flute geometry with a 42-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The centercutting design allows for plunge entry directly into the workpiece. With a 5/16 inch cutting diameter and 3/8 inch shank diameter, it is sized for use in standard milling machines, knee mills, and CNC machining centers requiring a smaller-diameter end mill.

This end mill is suited for light to medium milling work including slotting, profiling, and facing in job shop and production environments. The regular-length configuration with a 3/4 inch length of cut and 2-1/2 inch overall length makes it practical for shallow-to-moderate depth passes. Right-hand cut and right-hand flute orientation are standard for conventional spindle rotation. It is commonly used by machinists in tool rooms, maintenance shops, and manufacturing facilities working with mild steel, aluminum, brass, and similar materials.

Key Features

• M7 high speed steel construction for durability in general milling applications
• 42-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting design enables direct plunge milling without a pre-drilled entry
• 2-flute configuration provides ample chip clearance in slotting and pocket milling
• Uncoated finish suitable for use with or without cutting fluid
• Right-hand cut, right-hand flute for standard spindle operation

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machine spindles and CNC machining centers accepting a 3/8 inch straight shank end mill.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist. Secure the shank fully in a collet or end mill holder rated for the shank diameter and verify runout before cutting. Never exceed the recommended depth of cut for the material and diameter combination. Ensure spindle speed and feed rate are set according to established cutting data for M7 high speed steel tooling.
