Accupro 12182283 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12182283 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tool and die, and general machining applications. Built from micrograin carbide, it features a 3/8 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With three flutes and a spiral flute geometry, this tool balances material removal rate with surface finish quality. It is centercutting, allowing plunge entry into workpieces. Licensed machinists and CNC operators are the typical end users.

This end mill suits a wide range of milling operations including slotting, profiling, and contouring on ferrous and non-ferrous materials. The uncoated finish makes it a cost-effective choice for general-purpose work where a coating-specific application is not required. The long-length configuration with a 1 inch LOC provides additional reach for deeper pockets and stepped features without requiring an extended-reach tool. Right-hand cut and right-hand flute orientation make it compatible with standard CNC machining center and manual mill setups.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• 3/8 inch diameter with 1 inch length of cut for deeper pocket work
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge entry
• Three-flute spiral geometry balances feed rate and finish quality
• Right-hand cut and right-hand flute for standard spindle operation

Compatibility

Designed as a standard 3/8 inch shank square end mill for use in CNC machining centers, knee mills, and other milling machines equipped with collets or end mill holders accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder, torquing the retention hardware to the machine or toolholder specification. Verify runout after installation before beginning a cut, as excessive runout will accelerate tool wear and degrade surface finish.
