Accupro 12181315 Square End Mill 0.1969 in 2 Flute Carbide

Product Description

The ACCUPRO 12181315 is a solid carbide square end mill designed for high-precision milling operations in ferrous and non-ferrous materials. With a 0.1969-inch (5.00 mm) mill diameter and a 0.6299-inch (16.00 mm) length of cut, this tool handles slotting, profiling, and contouring passes where tight tolerances and clean wall finishes are required. The micrograin carbide substrate and TiCN coating provide hardness and wear resistance, while the 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. It is installed and used by machinists and tool-and-die professionals operating CNC machining centers and manual mills.

This end mill is suited for finish and semi-finish milling operations in job shops, production machining environments, and tool rooms. The regular-length geometry and 6.00 mm (0.2362-inch) shank diameter make it compatible with standard collet chucks and milling tool holders commonly found on vertical and horizontal machining centers. Right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling on most CNC and manual mill setups. The spiral flute design with no chipbreaker makes it appropriate for smooth-surface finish passes rather than heavy stock removal.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding materials
• TiCN coating increases surface hardness and lubricity for extended tool life
• 40-degree helix angle promotes efficient chip evacuation and lower cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute configuration for standard milling operations
• Mill diameter tolerance of +0.000 / -0.002 inch for precise fit and dimensional accuracy

Compatibility

Designed as an OEM-style replacement and standard-use solid carbide square end mill for use in collet chucks and end mill holders with a 6.00 mm bore, compatible with CNC machining centers and manual milling machines requiring a right-hand, 2-flute, regular-length tool in this diameter range.

Installation Notes

This tool is installed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Verify collet or holder bore matches the 6.00 mm shank diameter and that the shank is fully seated and clamped to the manufacturer torque specification for the holder type in use. Do not exceed the tool's rated depth of cut or engage materials outside the intended application range for TiCN-coated micrograin carbide.
