Accupro 12178606 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The ACCUPRO 12178606 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.5-inch cutting diameter, a 0.625-inch length of cut, and a 3-flute spiral configuration, this tool delivers efficient chip evacuation and consistent surface finish in ferrous and non-ferrous materials. The 40-degree helix angle promotes smooth cutting action and reduces chatter at moderate-to-high feed rates. Built from micrograin solid carbide, this end mill offers rigidity and wear resistance suited for CNC machining centers and manual mills. It is installed and used by machinists, toolroom operators, and CNC programmers in production and job-shop settings.

This end mill is suited for slotting, profiling, and peripheral milling in stub-length applications where rigidity is a priority over reach. The 0.5-inch shank diameter matches standard collets and end mill holders common to vertical machining centers. Its centercutting geometry allows plunge entry, expanding versatility in contouring and pocket-milling operations. The uncoated micrograin carbide substrate is appropriate for use with cutting fluids on steel, aluminum, and similar workpiece materials.

Key Features

• Solid micrograin carbide construction for wear resistance and edge integrity
• 3-flute spiral geometry with 40-degree helix angle for reduced cutting forces and improved chip flow
• Centercutting design permits direct plunge entry into workpiece material
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Stub length-of-cut range (0.600 to 0.700 inches) maximizes tool rigidity
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in close-tolerance work

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 0.5-inch collets, shrink-fit holders, and end mill holders on CNC vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended engagement depth in the holder and torque the retention mechanism per the holder manufacturer specification. Verify runout with a dial indicator before beginning cuts, and confirm cutting parameters are appropriate for the workpiece material and machine horsepower.
