Accupro 12182523 Square End Mill 23/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182523 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard plastic materials. Built from micrograin carbide, it delivers consistent cutting performance and edge retention in demanding machining environments. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 0.3594 inches in diameter with a 7/8 inch length of cut, this end mill is suited for slotting, profiling, and pocketing operations. It is a right-hand cut, right-hand flute tool with centercutting capability, allowing plunge entry into the workpiece. Machinists and tool-and-die professionals are the primary users of this type of cutting tool.

This end mill fits standard milling setups requiring a 3/8 inch shank diameter, making it compatible with common collet chucks and tool holders used in vertical machining centers, CNC mills, and manual knee mills. The 2-1/2 inch overall length and regular-length classification make it appropriate for general-purpose milling work where extended reach is not required. It is well suited for production shops, job shops, and maintenance machining applications working with ferrous and non-ferrous materials.

Key Features

• Micrograin solid carbide construction for improved hardness and wear resistance
• 4-flute spiral design with 40-degree helix angle for efficient chip flow and surface finish
• Centercutting geometry allows direct plunge cuts without pre-drilling
• Right-hand cut and right-hand flute configuration for standard milling setups
• Uncoated finish suitable for use with cutting fluids on a range of materials
• Tight mill diameter tolerance of plus 0.000 / minus 0.002 inches for dimensional accuracy

Compatibility

Designed as an OEM-style replacement and direct-use solid carbide square end mill for standard 3/8 inch shank collet chucks and milling tool holders used in CNC and manual milling applications.

Installation Notes

This end mill is installed by machinists using a collet chuck or end mill holder torqued to the machine tool manufacturer specifications. Always power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after seating the tool in the holder. Follow applicable shop safety protocols and machine tool operating guidelines when selecting feeds, speeds, and depth of cut.
