Accupro 14788475 Square End Mill 4 Flute 6mm Carbide

Product Description

The ACCUPRO 14788475 is a 4-flute solid carbide square end mill designed for precision milling operations in metal, composites, and engineered plastics. With a 6mm mill diameter and a 19mm length of cut, this centercutting end mill can plunge directly into workpiece material, enabling slot milling, profiling, and pocketing in a single tool. The helical flute geometry promotes chip evacuation and reduces cutting forces. The cylindrical shank measures 6mm in diameter, providing a secure grip in standard collet chucks and end mill holders. Solid carbide construction delivers rigidity and heat resistance beyond high-speed steel alternatives, supporting higher feed rates and longer tool life in demanding cutting environments.

This end mill suits general-purpose and production milling applications on CNC machining centers and manual knee mills. The 6mm diameter makes it well suited for detail work, narrow slot cutting, and finish passes in dies, molds, and fixture components. With an overall length of 63mm and no extended reach, it provides the stiffness needed to minimize deflection during aggressive side-milling passes. Machinists and tool-and-die makers working in job shops or maintenance environments will find it appropriate for both roughing and semi-finishing operations in ferrous and non-ferrous materials.

Key Features

• Centercutting geometry allows direct plunge entry into workpiece material
• 4 helical flutes promote efficient chip evacuation and smooth surface finish
• Solid carbide construction for rigidity, wear resistance, and elevated heat tolerance
• 6mm cylindrical shank fits standard collet chucks and end mill holders
• No chipbreaker for cleaner finish passes and consistent chip formation
• Compact 63mm overall length minimizes tool deflection in standard setups

Compatibility

Designed as an OEM-style replacement or standard tooling addition compatible with CNC machining centers and manual mills accepting a 6mm cylindrical shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum insertion depth recommended by the toolholder manufacturer to prevent pullout under cutting loads. Verify runout at the tool tip with a dial indicator before beginning the first cut, as excessive runout accelerates edge wear and degrades surface finish.
