Accupro 14788480 Square End Mill 4 Flute 19/64 in Carbide

Product Description

The ACCUPRO 14788480 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade materials. With a 4-flute helical configuration and a 19/64 inch (0.2970 inch) mill diameter, this tool delivers clean side and slot cuts with solid material removal rates. Centercutting geometry allows the tool to plunge directly into the workpiece, adding versatility to standard end milling applications. The cylindrical shank measures 5/16 inch in diameter, providing consistent, true-running grip in standard collet chucks and end mill holders. Overall weight is 0.07 pounds.

This end mill is suited for use on vertical mills, CNC machining centers, and manual knee mills in both production and job-shop environments. Its 3/4 inch length of cut and 2-1/2 inch overall length make it appropriate for shallow-to-moderate depth slotting, profiling, and peripheral milling. It is commonly used by machinists working with steel, aluminum, cast iron, and similar materials where a rigid, non-chipbreaker, non-extended-reach end mill is the correct tool selection.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 4-flute helical design for improved surface finish and chip evacuation
• Centercutting geometry supports direct plunge entry without pre-drilling
• Cylindrical shank for secure, concentric holding in standard collet systems
• Non-extended-reach, non-chipbreaker configuration for standard milling setups
• Compact overall length of 2-1/2 inches reduces deflection in short-reach applications

Compatibility

Designed as a direct-fit solid carbide end mill for use with standard 5/16 inch collet chucks, end mill holders, and compatible CNC or manual milling equipment requiring a 19/64 inch mill diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the machine spindle is fully stopped and de-energized before inserting or removing the end mill from the collet or holder. Confirm collet size matches the 5/16 inch shank diameter before tightening to prevent tool slippage or workpiece damage. Inspect the cutting edges for chips or wear before each use.
