Accupro 12183078 Square End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183078 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 2-inch length of cut, and a 4-inch overall length, this tool is built for long-reach applications where standard-length end mills fall short. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers the hardness and wear resistance needed for demanding ferrous and non-ferrous materials. It is a right-hand cut, right-hand flute configuration and is centercutting, allowing plunge entry. Machinists and CNC operators install this tool in production and job-shop settings.

This end mill is suited for slotting, profiling, and peripheral milling in general machining applications. Its long-length classification makes it a practical choice when clearance depth or workpiece geometry requires extended reach beyond standard tooling. The uncoated micrograin carbide substrate is appropriate for dry cutting or use with cutting fluid on a range of materials. A 0.5-inch shank diameter ensures compatibility with standard collets and tool holders used on CNC machining centers and manual mills.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• 4-flute configuration balances chip clearance with surface finish quality
• Long-length classification with 2-inch LOC and 4-inch OAL for extended-reach operations
• Right-hand cut and right-hand flute — standard CNC spindle compatible

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any CNC machining center or manual mill equipped with a 0.5-inch collet or tool holder accepting a 0.5-inch shank diameter end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or tool holder to the manufacturer-recommended engagement depth and tighten to the tool holder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish.
