Hertel 750612 Square End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The HERTEL 750612 is a solid carbide square end mill designed for precision milling in metal cutting and machining applications. Measuring 5/16 inches in diameter with a matching 5/16-inch shank, the tool features a 13/16-inch length of cut and a 2-1/2-inch overall length. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for hardened steels, stainless alloys, and non-ferrous materials. The AlTiN coating reduces heat buildup and extends tool life in dry or minimal-lubrication environments. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for slotting, profiling, and peripheral milling operations on machining centers and manual mills. The centercutting geometry allows direct plunge entry into the workpiece, adding versatility for pocketing operations. The 3-flute configuration balances chip room and rigidity, making it effective on a wide range of materials including ferrous and non-ferrous metals. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Micrograin solid carbide construction for high rigidity and edge retention
• AlTiN coating for thermal resistance and extended tool life in dry cutting
• 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design enables direct plunge entry for pocketing operations
• 3-flute geometry balances chip clearance and core strength
• Right-hand cut with standard 5/16-inch straight shank for broad collet compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for machining centers and manual mills accepting a 5/16-inch straight shank collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before commencing a cut, and confirm feed rate and spindle speed are appropriate for the workpiece material and depth of cut.
