Accupro 14788353 Square End Mill 2 Flute 5/16 Inch Carbide

Product Description

The ACCUPRO 14788353 is a 2-flute solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade plastic workpieces. With a mill diameter of 0.3130 inches (5/16 inch) and a helical flute geometry, this tool delivers clean, accurate cuts in a range of CNC and manual milling applications. The centercutting design allows direct plunge entry without a pre-drilled hole. A cylindrical shank and matching 0.3130-inch shank diameter ensure secure tool holding in standard collets and end mill holders. Solid carbide construction provides rigidity and wear resistance compared to high-speed steel alternatives.

This end mill suits general-purpose slotting, profiling, and peripheral milling on vertical machining centers and manual knee mills. The 0.5000-inch length of cut and 2-inch overall length make it appropriate for shallow-to-moderate depth passes in production and job-shop environments. Machinists working with aluminum, mild steel, stainless, brass, and engineering plastics will find this geometry well-suited to conventional and climb milling strategies.

Key Features

• Centercutting design allows direct plunge milling without a pilot hole
• Solid carbide construction for rigidity and extended tool life
• Helical flute geometry promotes chip evacuation and reduces cutting forces
• 2-flute configuration improves chip clearance in softer and gummy materials
• Cylindrical shank fits standard collet chucks and end mill holders
• Matched mill and shank diameter at 0.3130 inches simplifies tool holding selection

Compatibility

Designed as an OEM-style replacement solid carbide square end mill suitable for standard collet and end mill holder systems accepting a 5/16-inch cylindrical shank.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention hardware per the machine tool manufacturer specifications. Inspect the cutting edges for chipping before use and confirm runout with a dial indicator when precision tolerances are required.
