Hertel 750123 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750123 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.125 inch cutting diameter and 4-flute spiral geometry at a 30-degree helix angle, this tool delivers clean, accurate cuts in ferrous and non-ferrous materials. The uncoated carbide construction provides rigidity and edge retention in demanding cutting conditions. At 2.25 inches overall length with a 0.75 inch length of cut, this end mill is well suited for slotting, profiling, and peripheral milling operations performed by machinists and toolroom professionals.

This end mill is sized for tight-tolerance work on CNC machining centers, manual mills, and high-speed spindles. The 0.125 inch shank diameter matches standard collets and toolholders in that bore range. The centercutting geometry allows plunge entry directly into the workpiece, expanding its usefulness in contouring and pocketing operations. Right-hand cut and right-hand flute configuration is standard for conventional and climb milling on most machine tool setups.

Key Features

• Solid carbide construction for high rigidity and edge retention
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute for standard machine tool compatibility
• Uncoated finish suitable for a range of base materials
• 0.125 inch cutting diameter for fine-detail and tight-tolerance milling

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/8 inch collets and toolholders used on CNC machining centers and manual milling machines requiring square end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's runout and clamping specifications. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or toolholder to the recommended engagement depth to minimize deflection and vibration. Verify collet bore size matches the 0.125 inch shank before tightening.
