Accupro 14788424 Square End Mill 3 Flute 5/16 Inch

Product Description

The ACCUPRO 14788424 is a 3-flute solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 5/16-inch (0.3130-inch) mill diameter and a helical flute geometry set at a 38 to 42 degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action. The centercutting design allows the tool to plunge directly into workpiece material, expanding its versatility across slotting, profiling, and pocketing operations. Solid carbide construction provides the rigidity and wear resistance required for demanding cuts in ferrous and non-ferrous materials. This tool weighs 0.09 pounds and is sold individually.

This end mill is suited for use in CNC machining centers, vertical mills, and manual knee mills where a compact, high-performance cutting tool is needed. The 1-1/8-inch length of cut and 3-inch overall length make it well matched to shallow-to-medium depth milling tasks. The cylindrical shank fits standard collets and end mill holders sized for 5/16-inch tooling. Machinists and tool-and-die shops performing finish milling, contouring, and slotting on steel, aluminum, and similar materials will find this tool appropriate for general-purpose production work.

Key Features

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting 5/16-inch cylindrical shank end mills.

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible collet chuck or end mill holder torqued to machine manufacturer specifications. Ensure the machine spindle is fully powered down and locked out before changing tooling. Inspect the collet and holder for wear or contamination before seating the shank. Never exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
