Accupro 12182784 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182784 is a solid carbide square end mill designed for precise milling operations in metal, composites, and hard plastics. Built from micrograin carbide, it delivers consistent edge integrity and wear resistance across demanding cutting cycles. The 4-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 7/32 inch (0.2188 inch) in diameter with a 3/8 inch length of cut, this stub-length tool is well suited for rigidity-critical applications where deflection must be minimized. It is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.

This end mill fits applications requiring a compact, rigid cutting tool with a 1/4 inch shank for standard collet and end mill holder setups. The stub length overall at 2 inches makes it appropriate for pocketing, slotting, and profiling in tight workpiece clearances. The centercutting design allows plunge entry. Right-hand cut and right-hand flute configuration is standard for conventional milling setups. The uncoated finish suits use in applications where coating is not required or where regrinding is anticipated.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 4-flute spiral geometry with 40-degree helix angle for efficient chip flow and surface finish quality
• Centercutting capable — supports direct plunge milling entry
• Stub length design (2 inch OAL) maximizes rigidity and minimizes deflection
• Right-hand cut, right-hand flute — compatible with standard milling machine spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inch for consistent dimensional accuracy

Compatibility

Designed for use with standard 1/4 inch collets, end mill holders, and tool chucks on CNC machining centers and manual knee mills. No specific OEM system compatibility is stated by the manufacturer for this tool.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the spindle before inserting or removing the end mill from its holder. Ensure the shank is fully seated and the collet nut or set screw is torqued according to the toolholder manufacturer's specifications. Inspect the cutting edges for chips or damage before each use — a damaged carbide end mill should not be run.
