Accupro 14788522 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788522 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineered material applications. With a 7mm mill diameter, 4 helical flutes, and a centercutting geometry, this end mill supports both plunge and peripheral cutting without a separate pilot operation. The cylindrical shank measures 8mm in diameter, providing a secure grip in standard collets and toolholders. Overall length is 63mm with a 12mm length of cut, making it well suited for moderate-depth slot milling, profiling, and contouring on CNC machining centers and manual mills.

This end mill is intended for use in production and job-shop environments where tight tolerances and consistent surface finish are required. The solid carbide construction offers greater rigidity and wear resistance compared to high-speed steel tooling, particularly at elevated cutting speeds and feeds. Typical applications include slotting, side milling, and finish profiling on ferrous and non-ferrous workpieces. The helical flute design promotes efficient chip evacuation, reducing heat buildup at the cutting edge. This tool is installed and operated by machinists, CNC programmers, and tool-and-die professionals.

Key Features

• Solid carbide construction for rigidity and extended tool life at high cutting speeds
• 4 helical flutes for efficient chip evacuation and improved surface finish
• Centercutting geometry allows direct plunge entry into workpiece material
• 7mm mill diameter with 12mm length of cut for moderate-depth slotting and profiling
• 8mm cylindrical shank fits standard collets and toolholding systems
• No chipbreaker design suited for finishing and semi-finishing passes

Compatibility

Designed as an OEM-style replacement solid carbide end mill compatible with standard 8mm collets and cylindrical-bore toolholders used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Insert the shank to the recommended engagement depth in the collet or toolholder and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production run to confirm proper seating and minimize premature tool wear.
