Accupro 12182782 Square End Mill 13/64 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12182782 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 13/64 inch (0.2031 inch) cutting diameter, a 4-flute spiral configuration with a 40-degree helix angle, and a TiCN coating for improved wear resistance and heat management. The stub-length geometry keeps the tool compact and rigid, reducing deflection during aggressive cuts. This end mill is centercutting, allowing plunge entry into workpieces. It is installed and used by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill suits general-purpose milling in steel, stainless steel, cast iron, and similar ferrous materials where TiCN coating provides an advantage over uncoated carbide. The stub length and 3/8 inch length of cut make it well-suited for shallow-pocket milling, slotting, and side milling operations where rigidity is a priority. The 1/4 inch shank diameter fits standard ER collets, end mill holders, and other common 1/4 inch tool-holding systems found on CNC machining centers and knee mills.

Key Features

• Solid carbide micrograin construction for hardness and edge retention
• TiCN finish for improved abrasion resistance and extended tool life
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Right-hand cut, right-hand flute configuration — standard CNC orientation
• Stub length (2 inch OAL) minimizes overhang and deflection

Compatibility

Designed as a direct-fit replacement for standard 1/4 inch shank square end mills in ER collet chucks, end mill holders, and shrink-fit holders requiring a 1/4 inch shank diameter.

Installation Notes

Installation is performed by machinists using appropriate tool holders torqued per machine manufacturer specifications. Always power down and lock out the spindle before changing tooling. Verify runout after seating the end mill in the holder to avoid premature edge wear. Follow shop-specific speeds and feeds for the workpiece material and do not exceed the tool's rated length of cut of 3/8 inch.
