Accupro 14788513 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788513 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. This centercutting tool features 4 helical flutes with a helix angle of 38 to 42 degrees, enabling efficient chip evacuation and smooth cutting action. The 4.50mm mill diameter pairs with a 6.00mm cylindrical shank, giving machinists a secure, low-runout grip in standard collet chucks or end mill holders. Overall length is 63.00mm with a 9.50mm length of cut. Solid carbide construction provides the rigidity and heat resistance needed for aggressive feed rates and tight tolerances in production and job shop environments.

This end mill is suited for slotting, peripheral milling, and plunge cutting in CNC machining centers and manual knee mills. The centercutting geometry allows direct plunge entry into workpiece material without a pre-drilled hole. Typical applications include profiling, contouring, and pocket milling in ferrous and non-ferrous metals, engineering plastics, and composite materials. It is installed and used by machinists, tool and die makers, and CNC operators working in both production and prototype environments.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 4 helical flutes with 38 to 42 degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• 4.50mm mill diameter with 9.50mm length of cut for precise, controlled engagement
• 6.00mm cylindrical shank fits standard collet chucks and end mill holders
• No chipbreaker for clean, continuous cutting on finish and semifinish passes

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual milling machines accepting a 6.00mm cylindrical shank.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 6.00mm shank diameter. Ensure the holder and spindle are clean and free of chips before seating the tool. Confirm runout with a dial indicator before beginning cuts. Follow machine manufacturer torque specifications when tightening the holder drawbar or set screws.
