Hertel 12467638 Square End Mill 1/8 Inch 4 Flute Carbide

Product Description

The HERTEL 12467638 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.125-inch mill diameter and a 0.5-inch length of cut, this single-end tool handles slotting, profiling, and contouring in a compact form factor. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts. The 30-degree helix angle promotes smooth chip evacuation and stable cutting action. This tool is typically installed and operated by machinists and CNC programmers in shop environments.

This end mill is suited for light to medium-duty milling in ferrous and non-ferrous materials where a small-diameter, high-precision tool is required. The 1/8-inch shank diameter fits standard collet chucks and toolholders in CNC machining centers and manual mills. The bright uncoated finish makes it appropriate for applications where coatings could affect dimensional tolerances or where the operator prefers uncoated carbide for specific material compatibility. The overall length of 1.5 inches allows access to moderately deep features without excessive overhang.

Key Features

• Solid micrograin carbide construction for edge retention and wear resistance
• 4 flutes with a 30-degree spiral helix for efficient chip removal
• Centercutting geometry allows plunge cutting capability
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Bright uncoated finish suitable for a wide range of base materials
• Single-end design with 0.125-inch shank for use in standard collet systems

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using 1/8-inch collet chucks or toolholders. Part of the HSQSC4-CC series.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe locked-out state before changing tooling. Seat the shank fully into the collet and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cuts, particularly at this diameter, where any runout can significantly affect tool life and part accuracy.
