Accupro 14883451 Square End Mill 5/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14883451 is a single-end square end mill designed for precision milling operations in metal, composite, and engineering plastic workpieces. Built from micrograin solid carbide, it delivers higher hardness and wear resistance compared to HSS tooling, making it well suited for tight-tolerance profiling, slotting, and peripheral milling cuts. The tool measures 5/64 inches (0.0781 inches) in diameter with a 5/8-inch length of cut and a 30-degree helix angle. The bright/uncoated finish is appropriate for a wide range of materials where coating interaction is a concern or where regrinding is anticipated.

This end mill is used in CNC machining centers, manual knee mills, and precision benchtop mills where small-diameter tooling is required. Its 1/8-inch shank diameter fits standard collets and end mill holders common in light-duty spindles. The 3-flute geometry balances chip evacuation and tool strength at this diameter, making it practical for finishing passes and light to moderate material removal in ferrous and non-ferrous metals. It is a fractional-inch series tool intended for shops and machinists working to inch-based print tolerances.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• 3-flute spiral flute design balances chip clearance and core strength at 5/64 inches diameter
• 30-degree right-hand helix with right-hand cutting direction for standard milling applications
• Centercutting geometry allows plunge entry into the workpiece
• Bright/uncoated finish supports regrinding and broad material compatibility
• Single-end configuration; replace rather than flip when worn

Compatibility

Designed for use in standard 1/8-inch collets and end mill holders on CNC machining centers and manual milling machines. Part of the ACCUPRO ASQSC3-CC-30H series of fractional-inch solid carbide square end mills.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1/8-inch shank fully into the collet or holder and torque the retention hardware per the toolholder manufacturer specification. Inspect runout with a dial indicator after installation to confirm concentricity before commencing a cut.
