Accupro 12182538 Square End Mill 3/8 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12182538 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. Built from micrograin solid carbide with a TiCN (Titanium Carbonitride) coating, it delivers excellent wear resistance and edge retention at elevated cutting temperatures. The 4-flute, spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 3/8 inch in diameter with a 7/8 inch length of cut and 2-1/2 inch overall length, this centercutting tool handles slotting, profiling, and plunging in a compact, rigid package suited for CNC machining centers and manual mills.

This end mill is well suited for job shops, tool and die operations, and production machining environments working in ferrous and non-ferrous metals. The right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups. The regular-length profile makes it a practical choice for general-purpose side milling and full-slot cuts where extended reach is not required. It is installed and used by machinists and CNC operators across aerospace, automotive, mold making, and general metalworking applications.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiCN coating increases surface hardness and reduces friction for longer tool life
• 40-degree helix angle promotes efficient chip evacuation and reduced chatter
• Centercutting design allows direct plunge entry into the workpiece
• 4-flute spiral configuration delivers improved surface finish compared to 2-flute designs
• Mill diameter tolerance of +0.000 / -0.002 inches ensures precise dimensional accuracy

Compatibility

Designed as an OEM-style replacement and standard-fitment cutting tool for CNC machining centers and manual milling machines accepting a 3/8 inch straight shank. No specific compatible model or system data was provided in the product input.

Installation Notes

Installation is performed by machinists or CNC operators. The tool shank should be seated fully and concentrically in a collet or end mill holder rated for the 3/8 inch shank diameter before tightening. Always confirm spindle direction matches the right-hand cut orientation before engaging the workpiece. Inspect the cutting edges for chips or coating damage before each use, and follow applicable machine shop safety protocols when handling carbide tooling.
