Accupro 14788371 Square End Mill 2 Flute 5/32 in Solid Carbide

Product Description

The ACCUPRO 14788371 is a 2-flute solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastic workpieces. The tool features a 5/32 inch (0.1560 inch) mill diameter with a 3/4 inch length of cut, providing a clean square shoulder profile on each pass. A helical flute geometry with a 38 to 42 degree helix angle promotes smooth chip evacuation and reduced cutting forces. The centercutting design allows the tool to plunge directly into the workpiece without pre-drilling. Machinists and CNC operators running tight-tolerance work on vertical mills, machining centers, or manual knee mills rely on this geometry for slotting, profiling, and light pocket milling.

This end mill fits standard residential and commercial machine shop applications where small-diameter finish work is required. The 3/16 inch cylindrical shank fits common collet systems used on CNC machining centers and manual mills. With a 2-1/2 inch overall length, the tool provides adequate reach for shallow-to-moderate depth cuts. It is suited for finish passes and contour work where a clean square corner is required at the bottom of a feature. No chipbreaker geometry keeps the cutting edge continuous for smooth surface finishes on final passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Centercutting capability allows direct plunge entry without a pilot hole
• 38 to 42 degree helix angle promotes efficient chip flow and reduced heat buildup
• Helical flute design with no chipbreaker for consistent surface finish on finish passes
• Cylindrical shank is compatible with standard collet holders and tool holders
• Compact 5/32 inch diameter suited for fine detail work and narrow slot milling

Compatibility

Designed as an OEM-style replacement end mill for use in standard collet systems accepting a 3/16 inch cylindrical shank on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before inserting or removing the tool from the collet or tool holder. Ensure the collet bore and shank are clean and free of chips or coolant residue before seating the tool. Confirm runout with a dial indicator after seating to verify proper tool holding before beginning a cut.
