Accupro 14788502 Square End Mill 7/8 Inch 4 Flute Carbide

Product Description

The ACCUPRO 14788502 is a solid carbide square end mill designed for precision milling operations in metal-cutting and machining applications. Built with 4 helical flutes and centercutting capability, this tool handles slot milling, plunge cutting, profiling, and contouring. The 7/8 inch (0.8750 inch) mill diameter matches the shank diameter for a balanced, rigid setup. Solid carbide construction delivers hardness and heat resistance well beyond high-speed steel, making it a reliable choice for production environments where tool life and dimensional accuracy matter. Overall length is 4 inches with a 1-3/4 inch length of cut.

This end mill suits CNC machining centers and manual mills in job shops, tool rooms, and production facilities. Centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled pilot hole. The helical flute design promotes chip evacuation and reduces cutting forces, which is especially useful in ferrous and non-ferrous metals. Extended reach is not included, and no chipbreaker geometry is present, making this a straightforward general-purpose profile end mill for conventional milling setups.

Key Features

• Solid carbide construction for extended tool life in demanding materials
• 4 helical flutes for efficient chip evacuation and smooth surface finish
• Centercutting design permits direct plunge milling without pilot hole
• 7/8 inch mill diameter and matching 7/8 inch cylindrical shank for rigid tool holding
• 1-3/4 inch length of cut suitable for moderate-depth slotting and profiling
• No chipbreaker or extended reach — optimized for standard general-purpose milling

Compatibility

Designed as a general-purpose replacement solid carbide square end mill compatible with standard 7/8 inch tool holders and collet chucks used on CNC and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before tool changes. Seat the cylindrical shank fully and evenly in the collet or end mill holder and torque the retention hardware per the tool holder manufacturer specification. Inspect the cutting edges for chips or wear before each use, and confirm runout with a dial indicator when tolerance-critical work is planned.
