Accupro 14788392 Square End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788392 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With three helical flutes and a centercutting design, it allows for both plunge and peripheral cutting. The mill diameter measures 0.1410 inches (9/64 inch nominal) with a 3/16 inch cylindrical shank. The length of cut is 0.5000 inches, and overall length is 2 inches. A helix angle in the 38 to 42 degree range promotes efficient chip evacuation and reduces chatter during high-speed passes. This tool is installed and used by machinists and tool and die professionals working on CNC mills and manual knee mills.

This end mill is suited for finish and semi-finish milling of slots, pockets, and contours in ferrous and non-ferrous materials. The small diameter makes it well-suited for detailed work in die cavities, fixture components, and close-tolerance slots. It is appropriate for light-to-moderate material removal where dimensional accuracy is critical. The cylindrical shank fits standard collet chucks and end mill holders designed for 3/16 inch shanks.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Centercutting geometry enables direct plunge entry without pre-drilling
• Three helical flutes with a 38 to 42 degree helix angle for efficient chip flow
• 0.1410 inch (9/64 inch) mill diameter for fine detail work
• Cylindrical 3/16 inch shank fits standard collet and end mill holders
• No chipbreaker — suited for finishing passes and smooth surface requirements

Compatibility

Designed as an OEM-style replacement or standard cutting tool for CNC and manual milling machines accepting 3/16 inch shank end mills in standard collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist familiar with cutting tool holding systems. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. The shank must be fully seated in the collet or holder to the recommended grip depth to prevent pullout during cutting. Follow the machine tool manufacturer guidelines and applicable shop safety standards when selecting feeds, speeds, and depth of cut.
