Accupro 12179545 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179545 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 5/8 inch cutting diameter with a 1-1/4 inch length of cut and a matching 5/8 inch shank diameter, giving it a rigid, chatter-resistant setup in standard tool holders. The four-flute, single-end geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating provides elevated heat and wear resistance, extending tool life in ferrous and high-temperature alloy cutting environments. This end mill is centercutting, allowing direct plunge entry into the workpiece.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous metals, hardened steels, stainless steels, and similar materials where coating performance is a priority. The coarse pitch, right-hand cut, and right-hand flute configuration is the standard setup for CNC machining centers and manual vertical mills. With a 3-1/2 inch overall length and regular length classification, it fits typical production milling setups without requiring extended-reach tooling. Machinists, toolroom operators, and CNC programmers working in job shops or production environments will find this a direct fit for common roughing and finishing passes.

Key Features

• 5/8 inch cutting diameter with 1-1/4 inch length of cut for standard milling depth
• Solid carbide construction for rigidity and wear resistance versus high-speed steel alternatives
• AlTiN finish improves performance in high-heat cutting conditions and extends tool life
• Four-flute, 30-degree helix geometry balances chip clearance with surface finish quality
• Centercutting design permits direct plunge milling without a pre-drilled entry hole
• Right-hand cut and right-hand flute — standard orientation for most CNC and manual mill spindles

Compatibility

Designed for use in standard 5/8 inch ER, end mill, or set-screw tool holders on CNC machining centers and manual vertical milling machines. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the tool holder to the recommended gauge-line depth and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow the machine manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut based on workpiece material and machine rigidity.
