Accupro 14788468 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788468 is a 4-flute solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastic applications. The cutting edge geometry features helical flutes with a helix angle of 38 to 42 degrees, promoting efficient chip evacuation and reduced cutting forces. With a mill diameter of 4.50mm and a 16.00mm length of cut, this end mill is suited for slotting, profiling, and peripheral milling tasks where tight tolerances are required. The centercutting design allows the tool to plunge directly into the workpiece. Machinists and toolroom technicians are the primary users of this tool.

This end mill is used in CNC machining centers and manual milling machines for general-purpose material removal. The 6.00mm cylindrical shank fits standard collet chucks and tool holders with matching bore sizes. The overall length of 63.00mm provides adequate clearance for most workholding setups without excessive overhang. The solid carbide construction handles higher surface speeds and feeds compared to high-speed steel tooling, making it a practical choice for production environments running ferrous and non-ferrous materials. No chipbreaker geometry is present, so chip management relies on helix angle and coolant strategy.

Key Features

• Solid carbide construction supports higher cutting speeds and longer tool life than HSS alternatives
• 4 helical flutes with 38 to 42 degree helix angle for efficient chip evacuation
• Centercutting design enables direct plunge entry into the workpiece
• 4.50mm mill diameter with 16.00mm length of cut for precise slotting and profiling
• 6.00mm cylindrical shank fits standard collet and end mill holders
• 63.00mm overall length balances reach and rigidity in typical setups

Compatibility

Designed as a direct-fit replacement for standard 6.00mm cylindrical shank collet chucks and end mill holders used in CNC and manual milling applications requiring a 4.50mm diameter square end mill.

Installation Notes

A licensed machinist or toolroom technician should install this end mill using a properly sized collet or end mill holder torqued to the machine spindle specification. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after seating to confirm concentricity before initiating a cut. Avoid excessive overhang beyond what the setup requires, as extended reach increases deflection and reduces surface finish quality.
