Accupro 14788555 Square End Mill 1/2 Inch 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788555 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining. With a 1/2 inch mill diameter and 4 helical flutes, it delivers clean, accurate cuts in a wide range of workpiece materials. The centercutting geometry allows the tool to plunge directly into material, adding versatility to standard peripheral milling. A 3 inch length of cut and 6 inch overall length make it well suited for jobs requiring extended reach into pockets, slots, and profiling passes. Licensed machinists and CNC operators are the primary users of this tool class.

This end mill is used in CNC machining centers and manual knee mills for slotting, profiling, pocketing, and side milling operations. The helical flute geometry promotes chip evacuation and reduces cutting forces compared to straight-flute designs. The 1/2 inch cylindrical shank fits standard ER collet chucks, end mill holders, and Weldon-style tool holders. It is appropriate for both production environments and job shop applications where dimensional accuracy and tool life are priorities.

Key Features

• Centercutting design allows direct plunge entry into workpiece material
• 4 helical flutes for improved chip evacuation and surface finish
• Solid carbide construction for rigidity and wear resistance
• 1/2 inch cylindrical shank for compatibility with standard toolholding systems
• 3 inch length of cut supports deep pocket and slot milling
• 6 inch overall length provides extended reach capability

Compatibility

Designed as a standard 1/2 inch shank square end mill compatible with ER collet chucks, end mill holders, and other cylindrical-bore toolholding systems used in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Confirm the collet or toolholder bore matches the 1/2 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Inspect the cutting edges for chips or damage prior to use and verify runout with a dial indicator when tight tolerances are required.
