Hertel E8053012 Square End Mill 3/16 in 4 Flute Hss Tin

Product Description

The HERTEL E8053012 is a double-end square end mill designed for general-purpose milling in ferrous and non-ferrous materials. Built from M7 high speed steel with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduces cutting forces. With a 3/16 inch cutting diameter and 4-flute configuration, this end mill is suited for finishing passes and light slotting operations on manual mills and CNC machining centers. Both ends are usable, extending tool life per unit cost. Licensed machinists and toolroom technicians are the primary installers and operators.

This end mill is appropriate for use in job shops, toolrooms, and production environments where HSS tooling is preferred over carbide for its toughness and regrindability. The centercutting design allows plunge milling in addition to peripheral and slot milling. The right-hand cut and right-hand flute geometry is standard for conventional spindle rotation. With a 3/8 inch shank diameter and 3-1/4 inch overall length, it fits standard collets and end mill holders used on vertical knee mills and CNC machining centers.

Key Features

• Double-end design provides two usable cutting ends per tool
• M7 high speed steel construction for toughness in interrupted cuts
• TiN coating increases surface hardness and extends wear life
• 30-degree helix angle with spiral flutes for effective chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with any standard end mill holder or collet chuck accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before loading or changing end mills. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening to prevent runout and tool pullout. Inspect the TiN coating and cutting edges for chips or wear before each use; a damaged edge should not be run.
