Accupro 2500366 Square End Mill 7/32 in 3 Flute Carbide

Product Description

The ACCUPRO 2500366 is a solid carbide square end mill designed for precision milling in metal, composites, and other hard materials. It features a 7/32-inch (0.2188-inch) cutting diameter, a 3/8-inch length of cut, and three flutes with a 60-degree helix angle for aggressive chip evacuation and smooth cutting performance. The micrograin carbide construction provides rigidity and edge retention in demanding machining applications. This is a single-end, stub-length tool with a bright/uncoated finish, suited for high-precision work where tight tolerances are required.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and contouring operations. The stub-length configuration increases rigidity and reduces deflection in close-tolerance cuts. With a 1/4-inch shank diameter and 2-inch overall length, it fits standard 1/4-inch collets and tool holders commonly found in both production and job-shop environments. Right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. Machinists and tool-and-die professionals working in tight-clearance setups will find the compact geometry advantageous.

Key Features

• 7/32-inch (0.2188-inch) cutting diameter with a mill diameter tolerance of +0.000/-0.002 inches for precise sizing
• 3-flute spiral geometry with 60-degree helix angle for efficient chip removal and reduced heat buildup
• Micrograin solid carbide construction for superior hardness and edge retention versus high-speed steel
• Centercutting design allows plunge cutting as well as peripheral milling
• Bright/uncoated finish suitable for a wide range of materials without coating-compatibility concerns
• Stub-length body maximizes rigidity and minimizes deflection in close-quarters cuts

Compatibility

Designed as a drop-in replacement for standard 7/32-inch, 3-flute solid carbide square end mills with a 1/4-inch shank. Fits any tool holder or collet chuck accepting a 1/4-inch straight shank within the shank diameter tolerance of +0.0001/-0.0004 inches.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before mounting, verify the spindle is fully stopped and the machine is in a safe lockout state. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and confirm runout is within acceptable limits for the application.
