Hertel 750296 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750296 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous metals. It features a 5/8 inch cutting diameter, four flutes, and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. An AlTiN coating adds thermal and wear resistance, extending tool life in demanding cutting environments. With a 3 inch length of cut and a 6 inch overall length, this is an extra-long tool suited for deep-cavity work and hard-to-reach features. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual mills.

This end mill is well-suited for milling operations that require extended reach, including deep pockets, slots, and profiling passes where a standard-length tool cannot reach the workfloor. The right-hand cutting and right-hand flute direction make it compatible with standard CNC spindle rotation. The centercutting geometry allows for direct plunge entry without a pre-drilled pilot hole, which is useful in multi-step setups. The micrograin carbide substrate supports rigidity and edge retention at elevated cutting speeds.

Key Features

• Solid carbide micrograin substrate for rigidity and edge retention at high cutting speeds
• AlTiN coating provides thermal resistance and extended tool life in ferrous materials
• 4-flute, 30-degree right-hand spiral design promotes efficient chip evacuation
• Centercutting geometry allows direct plunge milling without a pilot hole
• Extra-long 6 inch overall length with 3 inch length of cut for deep-cavity reach
• 5/8 inch shank diameter matches standard collet and end mill holder sizes

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 5/8 inch shank. Suitable for milling ferrous metals, stainless steels, and hardened materials where AlTiN coatings are recommended.

Installation Notes

Install in a precision collet chuck or end mill holder rated for the 5/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the tool. Verify runout with a dial indicator before beginning cuts, especially given the extra-long reach, which increases sensitivity to deflection. Follow the tool manufacturer and machine OEM guidelines for feeds, speeds, and depth of cut for the specific workpiece material.
