Hertel E1053048 Square End Mill 3/4 in 4 Flute Hss

Product Description

The HERTEL E1053048 is a double-end, square-profile end mill manufactured from M7 high speed steel. It carries a 0.750-inch cutting diameter, a 1.625-inch length of cut, and a 0.750-inch shank diameter, with a 5.625-inch overall length. The 30-degree spiral flute geometry and four-flute configuration promote chip evacuation and surface finish in a wide range of ferrous and non-ferrous materials. The uncoated finish makes it straightforward to resharpen. This tool is installed and operated by machinists, tool-and-die makers, and CNC programmers working on manual mills or CNC machining centers.

This end mill is suited to general-purpose milling operations including slotting, profiling, and peripheral milling in production and job-shop environments. The centercutting design allows direct plunge entry into the workpiece, eliminating the need for a pre-drilled starting hole in many applications. Right-hand cut and right-hand flute orientation are standard for conventional spindle-forward operation. The double-end configuration effectively doubles tool life before the cutter is retired, making it a cost-efficient choice for medium-volume runs.

Key Features

• Double-end design provides two usable cutting ends for extended tool life
• M7 high speed steel construction offers toughness and ease of resharpening
• 30-degree helix angle promotes smooth cutting action and chip flow
• Centercutting capable — supports direct plunge milling without a pilot hole
• Uncoated finish allows straightforward regrinding in the shop
• Four-flute layout balances feed rate capacity with chip clearance

Compatibility

Designed as a general-purpose replacement or production end mill for standard 3/4-inch collet chucks, end mill holders, and Weldon-style tool holders used on vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine locked out per applicable shop safety procedures. Seat the shank fully in a clean, properly sized holder and torque the set screw or collet nut to the holder manufacturer specification. Inspect the cutting edges for chips or cracks before each use. High speed steel tooling should not be run at surface speeds appropriate for carbide; consult published HSS speed-and-feed tables for the workpiece material.
