Hertel 750506 Square End Mill 11/16 in 4 Flute Carbide

Product Description

The HERTEL 750506 is a solid carbide square end mill designed for precision milling in demanding shop environments. With an 11/16-inch (0.6875-inch) cutting diameter, four spiral flutes, and a 30-degree helix angle, it delivers efficient chip evacuation and smooth cutting action across a range of ferrous and non-ferrous materials. The AlTiN finish increases surface hardness and thermal resistance, extending tool life at elevated cutting speeds. This end mill is single-end, center-cutting, and features right-hand cut and right-hand flute geometry. It is installed and operated by machinists and CNC tool setters in production and job-shop environments.

This tool suits general-purpose and high-performance milling applications where dimensional accuracy and surface finish are critical. The 3/4-inch shank fits standard ER collet chucks, end mill holders, and milling machine spindles. The micrograin carbide substrate provides the rigidity needed for full-slotting, side milling, and profiling operations in steel, stainless, cast iron, and aluminum. The regular-length profile and 1-3/8-inch length of cut make it well-suited for shallow-to-moderate depth work in both vertical and horizontal machining centers.

Key Features

• 11/16-inch cutting diameter with 1-3/8-inch length of cut for versatile depth capability
• Solid micrograin carbide substrate for rigidity and extended tool life
• AlTiN coating for improved heat resistance and reduced tool wear at high surface speeds
• Four spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting geometry allows direct plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute configuration compatible with standard CNC and manual milling setups

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/4-inch end mill holders, ER collet chucks, and compatible milling machine spindles used in CNC and manual machining applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tool setter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before mounting. Seat the shank to the recommended engagement depth per the tool holder manufacturer specification and torque clamping hardware accordingly. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and reduces surface finish quality.
