Accupro 14788394 Square End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788394 is a 3-flute solid carbide square end mill designed for precision milling operations in metal, composites, and similar materials. With a mill diameter of 0.172 inches (11/64 inch) and a helical flute geometry, it produces clean, accurate cuts at tight tolerances. The centercutting design allows the tool to plunge directly into workpiece material, giving machinists flexibility for both slotting and profiling passes. At 2 inches overall length with a 0.625-inch length of cut, it fits standard toolholders and works across a range of CNC and manual milling setups. Solid carbide construction provides rigidity and wear resistance for demanding production environments.

This end mill is suited for job shops, production machining cells, and toolroom applications where small-diameter finish work is required. The 3/16-inch cylindrical shank fits common collet systems and shrink-fit holders. It is appropriate for use in vertical machining centers, knee mills, and CNC routers where precise small-feature cutting is needed. No chipbreaker geometry means it is optimized for smooth finishes rather than interrupted or heavy-chip cuts.

Key Features

• Centercutting design allows direct plunge entry without pre-drilling
• 3 helical flutes balance chip evacuation with cutting stability at small diameters
• Solid carbide construction provides rigidity and extended tool life versus HSS alternatives
• 0.172-inch (11/64 inch) mill diameter suits tight-tolerance small-feature work
• Cylindrical shank compatible with standard collet chucks and shrink-fit toolholders
• No chipbreaker — optimized for smooth surface finish applications

Compatibility

Designed as a replacement-style solid carbide square end mill compatible with standard 3/16-inch collet and toolholder systems used in CNC vertical machining centers, knee mills, and similar milling equipment.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and in a lockout/tagout state. Ensure the collet and holder are clean and free of chips before seating the shank to the recommended insertion depth. Do not exceed the tool manufacturer's rated speeds and feeds for the workpiece material. Inspect the cutting edges for wear or chipping before each use.
