Accupro 12182787 Square End Mill 15/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182787 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it offers a 15/64 inch (0.2344 inch) cutting diameter with a 3/8 inch length of cut and a 1/4 inch shank diameter. The 4-flute spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 2 inches overall length, this is a stub-length tool suited for rigid setups where deflection control is a priority. It is centercutting, allowing direct plunge entry into the workpiece. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual knee mills.

This end mill is used in general-purpose milling of ferrous and non-ferrous metals, plastics, and composite materials. Its stub-length geometry makes it a practical choice for short-reach pockets, slots, and profile cuts where rigidity is more important than reach depth. The uncoated finish is well suited for aluminum, brass, and softer steels where coating buildup is not a concern. Right-hand cut and right-hand flute orientation is standard for conventional CNC milling spindles.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• 4-flute spiral design with 40-degree helix angle for efficient chip removal
• Centercutting geometry allows direct plunge milling
• Stub-length configuration improves rigidity and reduces deflection
• Right-hand cut and right-hand flute for use in standard CNC spindles
• Uncoated finish suitable for aluminum, brass, and softer workpiece materials

Compatibility

Designed as an OEM-style replacement and standard-fit solid carbide square end mill for CNC machining centers and manual mills accepting a 1/4 inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by qualified machinists using a collet chuck or end mill holder rated for the 1/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout on the tool holder is within acceptable limits before engaging the cut, as excess runout accelerates wear on carbide tooling. Follow shop-standard feeds and speeds for the workpiece material and consult tooling documentation for recommended cutting parameters.
