Hertel 750424 Square End Mill 5/8 in 2 Flute Solid Carbide

Product Description

The HERTEL 750424 is a square end mill designed for precision milling operations in metal cutting, die work, and general machining applications. It features a 0.625-inch mill diameter, a 1.25-inch length of cut, and a 0.625-inch shank diameter with a 3.5-inch overall length. Constructed from micrograin solid carbide, the tool carries an AlTiN (aluminum titanium nitride) finish that improves heat resistance and extends tool life in ferrous and hard-material cutting. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows for direct plunge entry. This is a right-hand cut, single-end configuration.

This end mill is suited for CNC machining centers and manual knee mills in job shop, tool-and-die, and production environments. It handles slotting, peripheral milling, and plunge milling on steel, stainless, cast iron, and similar materials. The two-flute design provides generous chip clearance, making it a practical choice for full-slot cuts and pocketing where chip packing is a concern. Installation and use are handled by machinists and CNC operators working to established shop tolerances and fixturing standards.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN finish improves heat resistance in ferrous and hard-material applications
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut, two-flute design maximizes chip clearance in slot milling
• Matched shank and cutter diameter (0.625 inches) for direct collet or end mill holder mounting

Compatibility

Designed as a standard-shank square end mill compatible with 5/8-inch collets, end mill holders, and Weldon-style side-lock holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and machine power is off before inserting or removing the tool. Seat the shank fully into the holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before cutting to maximize tool life and dimensional accuracy.
