Accupro 14788478 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788478 is a 4-flute solid carbide square end mill designed for precision milling operations in metal, composite, and hard plastic workpieces. The cutter features a 17/64 inch (0.2660 inch decimal) mill diameter with a 3/4 inch length of cut, mounted on a 5/16 inch cylindrical shank. Helical flutes promote efficient chip evacuation and smooth cutting action. The centercutting geometry allows the tool to plunge directly into material, adding versatility for slotting and profiling passes. At 2.5 inches overall length, it fits standard toolholding systems on vertical mills and CNC machining centers. Machinists and toolroom operators rely on solid carbide construction for rigidity and wear resistance in demanding cutting applications.

This end mill suits general-purpose milling tasks including slotting, profiling, and peripheral cuts on ferrous and non-ferrous materials. The small diameter makes it well suited for detailed pocket milling, contour work, and tight-clearance features. It is commonly used on CNC vertical machining centers and manual knee mills in production shops, job shops, and maintenance toolrooms where consistent dimensional accuracy is required.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding cuts
• 4 helical flutes for efficient chip evacuation and smooth surface finish
• Centercutting geometry allows direct plunge entry into material
• 17/64 inch (0.2660 inch) mill diameter for small-feature and tight-tolerance work
• 3/4 inch length of cut suits shallow-to-moderate depth slot and profile operations
• Cylindrical 5/16 inch shank compatible with standard collet and endmill holders

Compatibility

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

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or endmill holder and tighten to the holder manufacturer's specified procedure before running. Inspect the cutting edges for chips or damage before each use; a damaged carbide edge can fracture under load.
