Accupro 14788397 Square End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788397 is a three-flute, solid carbide square end mill designed for precision material removal in milling applications. With a mill diameter of 0.2030 inches (13/64 inch) and a 0.6250-inch (5/8 inch) length of cut, this tool is built for accurate slotting, profiling, and peripheral milling. The helical flute geometry promotes smooth chip evacuation, and the centercutting design allows the tool to plunge directly into workpiece material. Solid carbide construction provides the rigidity and wear resistance required for consistent performance in ferrous and non-ferrous materials. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill suits applications requiring tight-tolerance cuts in aluminum, steel, brass, and similar machinable materials. The 0.2500-inch cylindrical shank fits standard collets and end mill holders commonly found on vertical machining centers, knee mills, and CNC routers. The 2.5-inch overall length provides adequate reach for most shallow-to-mid-depth pocket and contour work without sacrificing rigidity. Extended reach is not featured on this tool, keeping deflection low during aggressive passes.

Key Features

• Solid carbide construction for rigidity and long tool life
• Three helical flutes for efficient chip evacuation and smooth cutting action
• Centercutting design enables direct plunge entry into workpiece material
• 13/64 inch (0.2030 inch) mill diameter for precision small-diameter work
• Cylindrical 1/4 inch shank fits standard collets and end mill holders
• No chipbreaker geometry, suitable for finishing and semi-finishing passes

Compatibility

Designed as an OEM-style replacement and standard cutting tool for use in vertical machining centers, CNC mills, and manual knee mills equipped with a 1/4 inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before inserting or removing the end mill. Seat the cylindrical shank fully into the collet or holder to the recommended engagement depth and torque the retention nut per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
