Accupro 14788512 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788512 is a solid carbide square end mill designed for precision milling operations in metal, composites, and similar materials. With four helical flutes and a centercutting geometry, this tool removes material on both the tip and the periphery, allowing plunge cuts and full-slot milling in a single setup. The mill diameter measures 0.172 inches (11/64 inch), the length of cut is 0.375 inches (3/8 inch), and the overall length is 2 inches. A helix angle in the 38 to 42 degree range promotes smooth chip evacuation and reduces cutting forces at the spindle. This tool is installed and operated by machinists and CNC programmers on vertical and horizontal machining centers.

This end mill is suited for finish and semi-finish milling of ferrous and non-ferrous workpieces in job shop, production, and toolroom environments. The 3/16-inch cylindrical shank fits standard collets and end mill holders on CNC machining centers, knee mills, and manual milling machines. The solid carbide construction handles higher speeds and feeds than high-speed steel tooling, making it a practical choice for hardened or abrasive materials where tool life and dimensional accuracy are critical.

Key Features

• Centercutting design allows direct plunge entry without a pre-drilled hole
• Four helical flutes for efficient chip removal and improved surface finish
• 38 to 42 degree helix angle reduces radial cutting forces and chatter
• Solid carbide construction for extended tool life in hard or abrasive materials
• Cylindrical 3/16-inch shank for compatibility with standard collet systems
• No chipbreaker geometry for cleaner finish passes

Compatibility

Designed as an OEM-style replacement end mill for use in standard 3/16-inch collets and end mill holders on CNC machining centers, knee mills, and manual milling machines requiring a 0.172-inch mill diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut according to the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning a cut to protect both the workpiece and the tool.
