Accupro 14788388 Square End Mill 3 Flute 5/64 in Carbide

Product Description

The ACCUPRO 14788388 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 3-flute helical design and a mill diameter of 0.0780 inches (5/64 inch), this centercutting tool handles slotting, profiling, and plunge cuts in a single setup. The cylindrical shank measures 0.1250 inches (1/8 inch) in diameter, and the length of cut is 0.2500 inches (1/4 inch). Overall length is 1.5 inches. The solid carbide construction delivers the rigidity and wear resistance needed for consistent performance in ferrous and non-ferrous materials. Installed by machinists and CNC operators in production and toolroom environments.

This end mill is suited for light to medium milling work on machining centers, CNC mills, and manual milling machines. The small diameter and 3-flute geometry make it particularly effective for fine detail work, micro-milling, and tight-tolerance slot cutting. The helical flute design promotes chip evacuation during cutting passes. The helix angle ranges from 29 to 31 degrees, providing a balance between cutting efficiency and edge strength. This tool is appropriate for both production runs and prototype work where close dimensional control is required.

Key Features

• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• 3-flute helical design supports efficient chip evacuation and smooth finish
• Solid carbide construction for rigidity and extended tool life
• Helix angle of 29 to 31 degrees balances cutting force and edge durability
• Cylindrical shank fits standard collets and end mill holders
• No chipbreaker for clean, continuous cuts in fine detail work

Compatibility

Designed as an OEM-style replacement end mill for use in standard collet systems and end mill holders accepting a 1/8 inch cylindrical shank.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth before tightening. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when tolerances are critical.
