Hertel 750745 Square End Mill 0.5 in 2 Flute Solid Carbide

Product Description

The HERTEL 750745 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. With a 0.5-inch cutting diameter, a 3-inch length of cut, and a 2-flute geometry, this tool delivers efficient chip evacuation and clean edge finish in slotting, profiling, and peripheral milling operations. The AlTiN coating adds thermal resistance and surface hardness, extending tool life in dry or minimal-lubrication cutting. Micrograin carbide construction provides rigidity and resistance to edge chipping. Licensed machinists and CNC operators in production and job-shop environments are the primary users of this tool.

This end mill is suited for milling centers running ferrous alloys, stainless steels, hardened materials, and high-temp alloys where coating performance and substrate hardness are critical. The 30-degree helix angle promotes smooth cutting action and reduces vibration during deep-reach passes. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it versatile for pocketing and ramp-entry operations. The 0.5-inch shank fits standard ER collet chucks, end mill holders, and shrink-fit tooling with 0.5-inch bore capacity.

Key Features

• Solid micrograin carbide substrate for rigidity and edge retention
• AlTiN coating for elevated thermal resistance and extended tool life in dry cutting
• 2-flute design promotes chip clearance in slotting and deep pocket applications
• 30-degree helix angle reduces cutting forces and vibration
• Centercutting geometry permits direct plunge milling without a pilot hole
• Right-hand cut, single-end configuration for standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 0.5-inch bore end mill holders, ER collet chucks, and shrink-fit tooling systems used on vertical and horizontal CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
