Accupro 12181705 Square End Mill 11/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181705 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. It features a 0.6875-inch mill diameter with a 1-inch length of cut and a 3/4-inch shank diameter for secure tool holding in standard milling chucks and collets. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A TiCN (titanium carbonitride) coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. This end mill is installed by machinists and tool-and-die professionals in CNC and manual milling setups.

This end mill is suited for slotting, profiling, and plunge cutting operations in a wide range of shop environments. The centercutting geometry allows direct plunge entry into workpieces without pre-drilling. The right-hand cut, right-hand spiral flute configuration is standard for conventional CNC milling spindles. The stub-length body provides added rigidity, making it well suited for shorter-reach applications where deflection control is critical. It is appropriate for light to moderate material removal in both production and maintenance machining environments.

Key Features

• 0.6875-inch (11/16 inch) mill diameter with mill diameter tolerance of +0.000 / -0.002 inches
• Solid carbide micrograin construction for rigidity and edge retention
• TiCN coating for improved wear resistance and reduced friction in ferrous materials
• 40-degree helix angle with spiral flute for effective chip evacuation
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 3/4-inch milling collets, end mill holders, and Weldon-style tool holders used in CNC and manual vertical milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer torque and retention specifications. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Verify shank engagement depth meets the tool holder minimum grip requirement before machining. Always confirm spindle direction matches the right-hand cut orientation of this tool before beginning a cut.
