Accupro 12181694 Square End Mill 31/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181694 is a solid carbide square end mill designed for precision milling in metal-cutting applications. It features a 31/64 inch (0.4844 inch) cutting diameter, a 5/8 inch length of cut, and a 1/2 inch shank diameter, with an overall length of 2-1/2 inches. The stub-length profile and 40-degree helix angle combine to deliver rigidity and efficient chip evacuation. An AlTiN finish improves heat resistance and extends tool life in abrasive and high-temperature cutting conditions. The micrograin carbide substrate supports tight tolerances and consistent performance across repeated cuts. This tool is installed and used by machinists, tool-and-die professionals, and CNC operators in shop environments.

This end mill suits general-purpose and finish milling of ferrous and non-ferrous metals where a short, stiff tool is preferred. The stub-length geometry reduces deflection in tight-reach applications or when milling shallow pockets, slots, and profiles. The centercutting design allows plunge entry directly into the workpiece. Right-hand cut and right-hand spiral flute configuration make it compatible with standard CNC machining center and manual mill spindle rotation. The 2-flute count provides good chip clearance in softer materials and gummy alloys.

Key Features

• 31/64 inch (0.4844 inch) cutting diameter with tolerance of +0.000 / -0.002 inches
• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 40-degree helix angle spiral flute for efficient chip evacuation
• Centercutting design permits direct plunge milling
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/2 inch collet or end mill holder systems on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or CNC operator. The machine spindle must be fully stopped and the tool holder secured before inserting or removing the end mill. Use a properly sized collet or end mill holder matched to the 1/2 inch shank diameter, and verify runout before beginning a cut. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail suddenly if damage is present.
