Accupro 12183306 Square End Mill 0.5 in 4 Flute Carbide

Product Description

The ACCUPRO 12183306 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. Built from micrograin carbide, it delivers rigidity and edge retention in demanding cutting conditions. The cutter measures 0.5 inches in diameter with a 3-inch length of cut and a 6-inch overall length, placing it in the extra-long category for extended reach work. The 40-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Four flutes provide a balance of chip clearance and surface finish. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for slotting, profiling, and peripheral milling applications where reach beyond standard length is required. The extra-long 6-inch overall length allows access to deep pockets, tall workpiece features, and setups where a standard-length tool cannot reach. The centercutting design supports plunge entry. Right-hand cut and right-hand flute configuration is compatible with conventional milling machine and CNC machining center spindles. The uncoated finish makes it straightforward to resharpen when edge life is exhausted.

Key Features

• Micrograin solid carbide construction for edge retention in ferrous and non-ferrous materials
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting capability allows direct plunge entry without pre-drilling
• Extra-long 6-inch OAL with 3-inch length of cut for deep-reach applications
• Spiral flute, right-hand cut and right-hand flute for standard spindle compatibility
• Uncoated — suitable for regrinding to extend tool life

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 0.5-inch shank diameter.

Installation Notes

Installation is performed by machinists or tooling setup personnel. Ensure the spindle and tool holder are clean and free of chips before seating the 0.5-inch shank. Verify runout with a dial indicator after clamping, as runout directly affects tool life and surface finish on carbide end mills. Follow machine manufacturer torque specs for set screws or collet nuts — do not overtighten.
