Accupro 14788393 Square End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788393 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. With a 5/32 inch (0.1560 inch) mill diameter and three helical flutes, this centercutting end mill handles both peripheral and plunge cuts. The 38 to 42 degree helix angle promotes efficient chip evacuation and smooth cutting action. A 3/16 inch cylindrical shank and 2 inch overall length make it suitable for standard milling chucks and collet holders found in CNC and manual milling setups. Licensed machinists and tool-and-die professionals will find this a reliable small-diameter option for detailed slot and profile work.

This end mill is well suited for light to medium material removal in ferrous and non-ferrous alloys, as well as rigid plastics. Its compact 5/32 inch diameter makes it a practical choice for narrow slots, keyways, and tight-tolerance contouring where larger cutters cannot reach. The solid carbide construction provides the rigidity needed to maintain dimensional accuracy at higher feed rates compared to high-speed steel alternatives. Both CNC machining centers and manual knee mills with appropriate spindle speeds are typical deployment environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Three helical flutes with a 38 to 42 degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece material
• 5/32 inch mill diameter with a 1/2 inch length of cut for narrow slot and profile work
• Cylindrical 3/16 inch shank compatible with standard collets and end mill holders
• Non-chipbreaker, non-extended-reach design optimized for close-tolerance finish work

Compatibility

Designed as a standard small-diameter square end mill for use in CNC machining centers and manual milling machines equipped with collet systems or end mill holders sized for a 3/16 inch cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked before seating or removing the end mill from the collet or holder. Confirm proper shank engagement depth and torque the collet nut to the tool holder manufacturer specifications. Select spindle speed and feed rate appropriate for the workpiece material and the 5/32 inch cutter diameter before commencing the cut.
