Accupro 12185210 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12185210 is a double-end, solid carbide square end mill designed for precision milling in a wide range of ferrous and non-ferrous materials. It features a 7/32 inch (0.2188 inch) mill diameter with a 7/16 inch length of cut, a 1/4 inch shank diameter, and a 2-1/2 inch overall length. The four-flute, spiral configuration runs at a 40-degree helix angle and carries a TiCN (Titanium Carbonitride) finish that improves wear resistance and extends tool life in demanding cutting conditions. The micrograin carbide substrate provides the edge stability needed for tight-tolerance slots, pockets, and profiling operations. This tool is centercutting, allowing plunge entry into the workpiece.

This stub-length end mill is suited for light to medium milling operations in machine shops, maintenance facilities, and production environments. The double-end design delivers two usable cutting ends per tool, making it a practical choice for high-cycle toolroom use. It is installed and operated in CNC machining centers, knee mills, and manual milling machines by machinists and tool-and-die professionals. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups.

Key Features

• Double-end design provides two cutting ends per tool
• TiCN finish increases surface hardness and reduces built-up edge
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting capability allows direct plunge milling
• Micrograin solid carbide substrate for improved edge retention and rigidity
• Stub length classification improves stiffness and reduces deflection in short-reach applications

Compatibility

Designed as a standard shank end mill for use in 1/4 inch collets, end mill holders, and compatible toolholding systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the toolholder specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tooling.
