Accupro 12181715 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181715 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. Built from micrograin carbide stock, this 2-flute cutter features an AlTiN coating and a 40-degree helix angle that promotes efficient chip evacuation and extended tool life at elevated cutting temperatures. The 0.125-inch cutting diameter pairs with a 0.75-inch length of cut, making it well-suited for slotting, profiling, and plunge operations in tight geometries. Center-cutting capability allows direct plunge entry without a pre-drilled hole. Machinists, tool-and-die makers, and CNC programmers will find this end mill appropriate for finish and semi-finish passes where dimensional control is critical.

This end mill fits standard 0.125-inch collets and tool holders used on CNC machining centers, CNC routers, and manual knee mills. The long-length configuration, with a 2.25-inch overall length, provides additional reach for deeper pockets or workpiece setups that require clearance between the spindle and part fixture. Right-hand cut and right-hand flute geometry conform to standard CNC programming conventions, requiring no special G-code or toolpath compensation. Applications include mold and die work, aerospace component machining, and general precision part production where a small-diameter, high-performance end mill is required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating extends tool life at high cutting temperatures and speeds
• 40-degree spiral helix angle promotes chip flow and reduces cutting forces
• Center-cutting design allows direct plunge milling without pre-drilling
• 2-flute geometry suits slotting and pocket milling in tighter-tolerance applications
• Long-length OAL of 2.25 inches provides extra reach for deep-pocket work

Compatibility

Designed to fit standard 0.125-inch collet chucks and end mill holders on CNC machining centers, CNC routers, and manual mills accepting 1/8-inch shank tooling.

Installation Notes

This tool is installed and changed by machinists or CNC setup technicians. Always power down and lock out the spindle before changing tooling. Verify collet size and torque the collet nut to the tool holder manufacturer's specification using the appropriate spanner wrench. Confirm runout with a dial indicator before beginning a production cut, particularly at this diameter where even minor runout will affect tool life and surface finish.
