Accupro 14788464 Square End Mill 9/64 in 4 Flute Carbide

Product Description

The ACCUPRO 14788464 is a solid carbide square end mill designed for precision milling operations in metal, composite, and plastic workpieces. With 4 helical flutes and a centercutting geometry, this end mill supports both plunge cutting and peripheral milling in a single tool. The 9/64 inch (0.1410 inch) mill diameter and 1/2 inch length of cut make it well suited for tight-tolerance slot milling, profiling, and pocket work in small-feature applications. Licensed machinists and CNC operators select this tool where rigidity and edge retention are critical. The solid carbide construction delivers hardness and wear resistance that high-speed steel tooling cannot match in demanding cutting conditions.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines equipped with a collet or chuck accepting a 3/16 inch cylindrical shank. It is commonly used in job shops and production environments for finishing passes on ferrous and non-ferrous metals, as well as rigid plastics and composites. The helical flute geometry promotes efficient chip evacuation in narrow slots and small pockets. The non-extended-reach, non-chipbreaker design prioritizes stiffness and surface finish over reach in deep cavities.

Key Features

• Solid carbide construction for superior hardness and wear resistance
• 4 helical flutes for improved chip evacuation and surface finish
• Centercutting capability allows direct plunge entry into workpiece
• 0.1410 inch (9/64 inch) mill diameter for small-feature precision work
• 3/16 inch cylindrical shank fits standard collet toolholders
• 1/2 inch length of cut suitable for shallow slots and profiling passes

Compatibility

Designed as an OEM-style replacement and standard production end mill for CNC machining centers and manual mills using 3/16 inch collets or end mill holders with a cylindrical shank interface.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and the tool path program is cleared before changing tooling. Seat the cylindrical shank fully and evenly in the collet or holder before torquing to the toolholder manufacturer specification. Inspect the cutting edges for chipping before mounting, as carbide tooling is brittle and susceptible to micro-fracture if mishandled.
