Accupro 14788566 Square End Mill 3/8 Inch 4 Flute Carbide

Product Description

The ACCUPRO 14788566 is a 4-flute, solid carbide square end mill designed for precision milling operations in metal and hard material applications. Built with a centercutting geometry, this end mill can plunge directly into the workpiece, enabling versatile tool paths including slot milling, profiling, and pocket machining. The helical flute configuration promotes efficient chip evacuation and reduces cutting forces, contributing to longer tool life and cleaner surface finishes. With a mill diameter of 0.375 inches and an overall length of 3 inches, this tool fits standard CNC machining center and manual mill setups used by machinists and tool-and-die professionals.

This end mill is suited for residential shop, production floor, and job shop environments where close-tolerance material removal is required. The cylindrical shank seats securely in standard collet chucks and end mill holders. Its 1.375-inch length of cut provides sufficient flute engagement for common depth-of-cut requirements in ferrous and non-ferrous materials. Machinists working with aluminum, mild steel, stainless, and similar materials will find this a reliable general-purpose cutting tool.

Key Features

• Centercutting design allows direct plunge cuts without pre-drilling
• Solid carbide construction for rigidity and wear resistance in hard materials
• 4 helical flutes promote efficient chip evacuation and smooth finish
• 0.375-inch mill diameter matches 3/8-inch shank for balanced tool geometry
• 1.375-inch length of cut suits standard slotting and profiling operations
• Cylindrical shank compatible with standard collet and end mill holder setups

Compatibility

Designed as a general-purpose replacement-style square end mill for use in CNC machining centers and manual knee mills accepting 3/8-inch cylindrical shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Secure the shank fully within the collet or end mill holder to the recommended grip length before tightening. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after seating to confirm proper alignment before cutting.
