Hertel E1030028 Square End Mill 7/16 in 2 Flute Hss

Product Description

The HERTEL E1030028 is a 2-flute square end mill designed for general-purpose milling in metal, alloy, and ferrous materials. Manufactured from M7 high speed steel in an uncoated finish, it features a 30-degree helix angle with right-hand cut and right-hand spiral flutes. The 7/16-inch cutting diameter and 13/16-inch length of cut make this a regular-length tool suited for slotting, profiling, and peripheral milling operations. Center-cutting geometry allows plunge entry without a pre-drilled hole. Machinists and tool-and-die professionals use this end mill in manual knee mills and CNC machining centers for everyday stock removal and finishing work.

This end mill is appropriate for light to medium-duty machining in job shop, maintenance, and production environments. The 3/8-inch shank diameter fits standard R8 collets, ER collets, and end mill holders common to knee mills and vertical machining centers. The 2-1/2-inch overall length keeps tool overhang minimal, improving rigidity and reducing chatter during cuts. It is well suited for non-extended-reach applications where a standard projection is sufficient.

Key Features

• 7/16-inch cutting diameter with 13/16-inch length of cut
• M7 high speed steel construction for toughness and grindability
• 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge entry
• Right-hand cut and right-hand flute for conventional CNC and manual mill setups
• Uncoated finish for compatibility with re-sharpening workflows

Compatibility

Designed as a standard-shank replacement end mill for use in any machine tool accepting a 3/8-inch shank; fits common R8, ER, and straight-bore end mill holders used in vertical knee mills and CNC machining centers.

Installation Notes

Installation is performed by a machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the drawbar or clamping nut to the machine manufacturer's specification. Inspect cutting edges for chips or wear before each use; a damaged edge on an uncoated HSS tool can be re-ground by a qualified tool grinder.
