Accupro 12179061 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12179061 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. The cutter measures 7/16 inches in diameter with a 1-3/8 inch length of cut and a 4-inch overall length. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. The nACRo (nanocomposite aluminum-chromium) coating improves heat resistance and wear life compared to uncoated carbide. Micrograin carbide construction maintains edge integrity at higher feed rates and speeds. This end mill is suitable for machinists and tooling professionals running CNC milling machines or manual knee mills in job shop and production environments.

This end mill is well suited for slotting, profiling, and peripheral milling operations on steel, stainless, cast iron, and similar materials. The centercutting geometry allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled start hole in many applications. Right-hand cut and right-hand flute configuration follows standard CNC and manual mill spindle conventions. The 7/16 inch shank diameter fits standard ER collets, side-lock holders, and shrink-fit toolholders in that size range.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• nACRo coating for improved wear resistance and heat dissipation
• 40-degree helix angle for aggressive chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without a pilot hole
• 4 flutes for balance between chip clearance and surface finish quality
• Right-hand cut, right-hand flute — standard configuration for most CNC spindles

Compatibility

Designed as a standard square end mill for use in CNC machining centers and manual milling machines accepting 7/16 inch shank toolholders. No specific machine model compatibility was stated by the manufacturer for this part number.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool is seated to the full shank engagement depth recommended by the toolholder manufacturer before tightening. Confirm runout with a dial indicator before cutting to protect edge life. Inspect collets and toolholders for wear or contamination that could compromise concentricity.
