Hertel E8053022 Square End Mill 11/32 in 4 Flute Hss Tin

Product Description

The HERTEL E8053022 is a double-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. The cutting diameter is 0.3438 inches (11/32 inch) with a 0.75-inch length of cut and a 3/8-inch shank diameter. The 30-degree spiral helix and four right-hand flutes promote efficient chip evacuation during slotting, profiling, and shoulder milling. Licensed machinists and tool-and-die technicians are the primary users of this tool.

This end mill suits vertical and horizontal machining centers, knee mills, and manual bridgeport-style mills in job shops, maintenance facilities, and production environments. Its centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled starting hole. The double-end design provides two usable cutting ends, extending overall tool value per unit. It is well suited for light to moderate material removal in carbon steel, alloy steel, aluminum, and similar machinable materials.

Key Features

• M7 high speed steel construction for toughness in interrupted cuts
• TiN coating reduces friction and extends cutting edge life
• 30-degree helix angle promotes smooth chip flow and reduced chatter
• Centercutting capable — supports plunge milling without a pilot hole
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand flute for standard CNC and manual mill spindles

Compatibility

Designed as a standard 3/8-inch shank square end mill compatible with ER collets, end mill holders, and Weldon-style set-screw holders used in vertical milling machines and machining centers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Seat the shank to the full recommended grip length in the holder — a minimum of 3 times the shank diameter is the general industry guideline for secure clamping. Inspect the collet or holder for runout before commencing cuts to avoid premature edge wear.
