Hertel 750222 Square End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750222 is a 4-flute solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/16 inch cutting diameter with a 5/8 inch length of cut, a 3/16 inch shank diameter, and a 2 inch overall length. The micrograin carbide substrate and AlTiN finish provide heat resistance and extended tool life at elevated cutting speeds. A 30-degree spiral helix angle promotes efficient chip evacuation. This end mill is sold individually and intended for use by machinists, tool-and-die makers, and CNC operators working in production or job-shop environments.

The 750222 is suited for slotting, profiling, and contouring operations on CNC machining centers and manual mills. Its centercutting design allows direct plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute configuration follows standard tooling convention. The regular-length geometry makes it appropriate for general-purpose work where extended reach is not required. The AlTiN coating is well suited to dry or minimal-lubrication cutting strategies in hardened and abrasive materials.

Key Features

• 3/16 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in tight-tolerance work
• 4-flute configuration balances chip load and surface finish in finish-milling passes
• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN finish for high-temperature resistance and extended tool life
• Centercutting design enables direct plunge milling without a pilot hole
• 30-degree helix angle promotes smooth cutting action and chip evacuation

Compatibility

Designed as a standard-shank square end mill for use in CNC machining centers, knee mills, and manual milling machines accepting a 3/16 inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in a properly sized collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before committing to a production cut.
