Accupro 12182118 Square End Mill 11/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182118 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With an 11/16 inch (0.6875 inch) mill diameter and a 1-1/2 inch length of cut, this tool delivers accurate, repeatable material removal in a range of ferrous and non-ferrous applications. The micrograin carbide construction provides the rigidity needed for demanding cuts. The 40-degree helix angle promotes efficient chip evacuation and reduces heat buildup. Installed and operated by machinists and toolroom professionals, this end mill fits standard CNC machining centers and manual mills with a 3/4 inch collet or toolholder.

This end mill is suited for slotting, profiling, and peripheral milling in production and toolroom settings. The bright uncoated finish makes it a practical choice for aluminum, brass, and other non-ferrous materials where coated tools may not be preferred. The regular-length geometry and 4 inch overall length keep the tool stiff and deflection-resistant in typical setups. Centercutting capability allows plunge entry, adding flexibility for pocket milling without a pre-drilled entry point.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• 40-degree spiral flute helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute orientation for standard spindle use
• Bright uncoated finish suited for non-ferrous and general-purpose machining
• 3-flute geometry balances chip clearance and cutting edge strength

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 3/4 inch shank diameter with standard collet or end mill toolholders.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures. Ensure the spindle is fully powered down and the machine is in a safe state before mounting or removing tooling. Verify collet size matches the 3/4 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Follow the machine tool manufacturer torque specifications for collet nut tightening and confirm runout with a dial indicator before initiating cuts.
