Accupro 12181284 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181284 is a solid carbide square end mill designed for precision milling in a wide range of metalworking and machining applications. With a 0.1719 inch (11/64 inch) cutting diameter, a 2-flute spiral geometry, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and clean edge profiles in ferrous and non-ferrous materials. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. Centercutting capability allows plunge milling directly into a workpiece without a pre-drilled entry point. This tool is installed and operated by machinists and CNC programmers working in job shops, production facilities, and maintenance machining environments.

This end mill fits applications requiring a compact cutting diameter with a regular-length reach. The 5/8 inch length of cut and 3/16 inch shank diameter make it well suited for slotting, profiling, and pocket milling in tight geometries. Right-hand cut and right-hand flute direction conform to standard CNC machining center and manual mill setups. The uncoated finish is appropriate for use in aluminum, brass, and other non-ferrous materials, or in applications where a coating is not specified.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree helix angle promotes efficient chip flow and smooth cutting action
• Centercutting design allows direct plunge entry without pre-drilling
• 2-flute spiral geometry suits slotting and pocket milling in softer materials
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Uncoated finish for compatibility with non-ferrous and general-purpose machining

Compatibility

Designed as a standard shank end mill for use in CNC machining centers, knee mills, and toolroom milling machines equipped with collet or end mill holders accepting a 3/16 inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before loading or changing tooling. Secure the shank in a properly sized collet or end mill holder and verify runout with a dial indicator before cutting. Follow machine tool manufacturer torque specifications for drawbar and collet nut tightening.
