Accupro 14788546 Square End Mill 5/8 Inch 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788546 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering material applications. Built with 4 helical flutes and a centercutting geometry, this tool removes material efficiently in both peripheral and plunge cutting. The mill diameter and shank diameter are both 5/8 inch (0.6250 inches), providing a rigid, balanced setup that reduces chatter. With a 2-1/8 inch length of cut and an overall length of 4-5/8 inches, this end mill suits standard depth-of-cut requirements on CNC machining centers and manual knee mills. Solid carbide construction delivers hardness and thermal resistance beyond high-speed steel alternatives, supporting higher feed rates and longer tool life in demanding cuts.

This end mill is used in production and job-shop environments where tight tolerances and clean surface finishes are required. It is suited for profiling, slotting, and face milling operations on ferrous and non-ferrous workpieces. The cylindrical shank fits standard collet and end mill holder tooling systems. Its compact overall length of 4-5/8 inches makes it appropriate for setups where machine clearance and tool overhang are concerns. Machinists, CNC operators, and tool room technicians are the primary users of this tool in both prototype and high-volume production settings.

Key Features

• 4 helical flutes for efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry into the workpiece
• Solid carbide construction for superior hardness and heat resistance
• 5/8 inch mill diameter and matching 5/8 inch cylindrical shank for balanced rigidity
• 2-1/8 inch length of cut supports standard depth-of-cut requirements
• No chipbreaker geometry, suited for full-flute finishing and semi-finishing passes

Compatibility

Designed as a standard-geometry square end mill compatible with 5/8 inch collets, end mill holders, and shrink-fit tooling systems used on CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with toolholder torque procedures and runout inspection. Always verify that the collet or holder is clean and free of debris before seating the shank. Confirm proper tool projection and overhang before initiating any cut to avoid deflection or tool pull-out. Never exceed the tool manufacturer's recommended cutting parameters for the workpiece material.
