Accupro 12179048 Square End Mill 7/16 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12179048 is a solid carbide square end mill designed for precision milling in demanding machining environments. Built from micrograin carbide, this single-end tool features four spiral flutes with a 40-degree helix angle and an nACRo finish that improves wear resistance and heat dissipation. The mill diameter measures 7/16 inches (0.4375 inches) with a 3-inch length of cut and a 6-inch overall length. Right-hand cut and right-hand flute orientation are standard. Center-cutting capability allows this tool to plunge directly into workpiece material. Machinists and CNC operators in production and job-shop environments rely on this geometry for clean, accurate results in ferrous and non-ferrous materials.

This end mill is suited for milling slots, pockets, profiles, and contours on vertical and horizontal machining centers. The 40-degree helix promotes efficient chip evacuation, reducing heat buildup in deep-pocket applications. The 3-inch length of cut accommodates medium-depth passes without sacrificing rigidity. The 7/16-inch shank diameter matches the mill diameter for straightforward toolholder selection. This tool is appropriate for production runs and prototype work where tight tolerances and consistent tool life are required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• nACRo finish extends tool life in abrasive and dry-cutting applications
• 40-degree spiral helix promotes efficient chip evacuation
• Center-cutting design allows direct plunge entry into material
• Right-hand cut and right-hand flute for standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 7/16-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the toolholder to the minimum clamping depth specified by the holder manufacturer to prevent pullout under load. Verify runout with a dial indicator before beginning a production cut.
