Hertel 12378418 Square End Mill 3/32 in 2 Flute Carbide

Product Description

The HERTEL 12378418 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers the hardness and edge retention required for cutting ferrous and non-ferrous materials. The 2-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 3/32 inches in diameter with a 3/8-inch length of cut, this end mill is sized for fine detail work, slot milling, and tight-tolerance profiling. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern. Licensed machinists and tool-and-die professionals are the typical users of this tool.

This end mill fits standard CNC machining centers, manual knee mills, and high-speed spindle setups that accept a 1/8-inch shank. The 3/32-inch diameter makes it well suited for small-feature milling, engraving prep, and narrow slot work in dies, molds, and precision components. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled start hole. The single-end configuration and 1-1/2-inch overall length keep it rigid in short-reach setups where deflection control is critical.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 2-flute spiral design with 30-degree helix angle for efficient chip removal
• Centercutting capability allows direct plunge milling without a pilot hole
• Bright uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end design with 1/8-inch shank for use in collets and end mill holders

Compatibility

Designed for use in machining centers and milling machines fitted with collets or end mill holders that accept a 1/8-inch shank diameter. Part of the HERTEL HSQSC2-CC series of solid carbide square end mills.

Installation Notes

Installation is performed by qualified machinists following standard tooling setup procedures. Secure the shank fully in a collet or end mill holder to the manufacturer-specified engagement depth before use. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the tool edge for chips or damage before each use, as carbide tools are brittle and can fracture if run with edge defects.
