Accupro 12181796 Square End Mill 7/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181796 is a solid carbide square end mill designed for precision milling in demanding shop environments. It features a 7/16 inch cutting diameter, a 1-3/8 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for reach into deeper pockets and slots. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. With a 40-degree helix angle and spiral flute geometry, this end mill promotes efficient chip evacuation and smooth cutting action. It is installed and operated by machinists and CNC tool-and-die professionals.

This end mill is suited for milling operations on ferrous and hardened materials where an AlTiN-coated, micrograin carbide tool is appropriate. The extra-long configuration allows access to deeper features without requiring a longer reach holder. It is centercutting, enabling direct plunge entry. Right-hand cut and right-hand flute orientation match standard spindle configurations found on vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN finish for heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge milling
• Extra-long length of cut (1-3/8 inches) reaches deeper part features
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit replacement or new-install solid carbide square end mill for standard 7/16 inch collets and tool holders on CNC machining centers and manual mills configured for right-hand rotation.

Installation Notes

Installation should be performed by qualified machinists following shop safety procedures. Power down and lock out the spindle before inserting or removing tooling. Seat the shank fully in a clean, properly sized collet or end mill holder and torque the retention mechanism to the holder manufacturer's specification. Inspect the collet and holder for runout before beginning a cut, as excessive runout will reduce tool life and surface finish quality.
