Hertel 12467670 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The HERTEL 12467670 is a single-end, solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 2.5 inch overall length with a 1/4 inch shank diameter. The 4-flute, spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and a smooth surface finish. Constructed from micrograin solid carbide, this end mill delivers the rigidity and wear resistance needed for demanding cutting applications. It ships in a bright, uncoated finish suitable for use in a range of workpiece materials.

This end mill is suited for milling slots, profiles, and pockets on CNC machining centers and manual mills. The centercutting geometry allows for direct plunge entry into the workpiece without pre-drilling. Right-hand cut and right-hand flute direction make it compatible with standard spindle configurations. It is intended for use by machinists and tooling professionals in job shops, production facilities, and maintenance machining environments where tight tolerances and consistent tool life are required.

Key Features

• Micrograin solid carbide construction for high rigidity and extended tool life
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting capable — supports direct plunge milling without a pilot hole
• Bright, uncoated finish — ready for use across a broad range of materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end design with a 1/4 inch shank for secure toolholder engagement

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collet chucks, end mill holders, and toolholders accepting 1/4 inch round shanks on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the shank is clean and fully seated in the toolholder before torquing the retention mechanism to the toolholder specification. Do not exceed the recommended depth of cut or feed rate for the workpiece material and tool diameter. Inspect the cutting edges for wear or chipping before each use.
