Accupro 14788483 Square End Mill 4 Flute 21/64 in Carbide

Product Description

The ACCUPRO 14788483 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. This centercutting, 4-flute tool features a helical flute geometry that promotes chip evacuation and smooth cutting action. The mill diameter measures 0.3280 inches (21/64 inch) with a 3/8-inch cylindrical shank. The length of cut reaches 7/8 inch, and the overall length is 2.5 inches. Solid carbide construction delivers the rigidity and heat resistance required for high-speed, close-tolerance work on CNC machining centers and manual mills.

This end mill is suited for slotting, profiling, and plunging operations in production and job-shop environments. The centercutting capability allows direct plunge entry without a pre-drilled pilot hole. The helical flute design supports efficient chip removal in both climb and conventional milling strategies. Typical applications include contour milling, pocket milling, and finishing passes on ferrous and non-ferrous workpieces where dimensional accuracy and surface finish are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• 4 helical flutes for improved chip evacuation and surface finish
• Centercutting geometry allows direct plunge entry into the workpiece
• 21/64 inch (0.3280 inch) mill diameter with a 3/8 inch cylindrical shank
• 7/8 inch length of cut with 2.5 inch overall length for versatile reach
• No chipbreaker and no extended reach — standard geometry for general-purpose precision work

Compatibility

Designed as a standard-geometry solid carbide square end mill for use in CNC machining centers, knee mills, and manual milling machines accepting a 3/8 inch cylindrical shank tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the shank fully within the tool holder to the recommended engagement depth per the holder manufacturer guidelines, and verify runout with a dial indicator before production use. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and depth of cut.
