Accupro 14788416 Square End Mill 3 Flutes 3/8 Inch Carbide

Product Description

The ACCUPRO 14788416 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With 3 helical flutes and a centercutting geometry, this end mill can plunge directly into material as well as perform peripheral and slot milling. The 3/8 inch mill diameter and 5/8 inch length of cut make it well-suited for moderate-depth slotting, profiling, and contouring passes. The helix angle ranges from 38 to 42 degrees, promoting efficient chip evacuation and smooth cutting action. Solid carbide construction delivers the rigidity and wear resistance required for consistent performance in production environments.

This end mill is used in CNC machining centers and manual vertical mills across job shop and production floor settings. It is appropriate for ferrous and non-ferrous metals where a sharp, rigid cutting tool is needed for finish or semi-finish passes. The cylindrical shank accepts standard 3/8 inch collets and end mill holders commonly found in most spindle tooling setups. Machinists, tool-and-die makers, and CNC operators working in aerospace, automotive, and general precision machining will find this tool a straightforward fit for typical 3/8 inch toolpath programs.

Key Features

• Solid carbide construction for superior rigidity and wear resistance compared to HSS tooling
• 3 helical flutes for efficient chip removal and reduced cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• 38 to 42 degree helix angle promotes smooth chip evacuation in slotting and profiling cuts
• Cylindrical shank fits standard 3/8 inch collets and end mill holders
• Non-extended-reach geometry provides maximum rigidity for precision work

Compatibility

Designed as a direct-fit replacement for standard 3/8 inch shank end mill positions in CNC machining centers and manual vertical mills using ER, TG, or straight-bore end mill holders sized for 3/8 inch cylindrical shanks.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a locked-out, de-energized state before any tool change. Ensure the collet or holder bore is clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping to confirm proper tool seating. Follow the machine manufacturer and tooling supplier guidelines for appropriate clamping torque on the collet nut.
