Accupro 14883477 Square End Mill 0.04 in 3 Flute Carbide

Product Description

The ACCUPRO 14883477 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 0.04-inch cutting diameter and a 31/64-inch (0.48-inch) length of cut, this tool is built for tight-tolerance work in small-feature machining. The three-flute, right-hand spiral geometry with a 30-degree helix angle balances chip evacuation and surface finish. An AlTiN (aluminum titanium nitride) coating extends tool life in hard and abrasive materials by improving heat resistance at the cutting edge. The micrograin carbide substrate provides the rigidity and edge retention required for consistent results in ferrous and non-ferrous metals.

This end mill is suited for CNC machining centers and manual mills where small-diameter, high-precision cuts are required. Typical applications include slotting, profiling, and contouring of hardened steels, stainless steel, titanium, and high-temp alloys. The center-cutting geometry allows plunge entry. With a 1/8-inch shank and 2.5-inch overall length, it fits standard collet toolholders used in production and job-shop environments. The single-end configuration means the tool is replaced rather than flipped when worn, maintaining dimensional accuracy across operations.

Key Features

• 0.04-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• 3-flute, right-hand spiral flute design with 30-degree helix angle for balanced chip removal
• Center-cutting capable — supports direct plunge entry
• Micrograin solid carbide substrate for superior rigidity and edge retention
• 1/8-inch shank diameter with tolerance of -0.0001 / -0.0003 inches for secure collet engagement

Compatibility

Designed as an OEM-style replacement or direct-use tooling for CNC machining centers and manual mills accepting a 1/8-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing the tool from the collet holder. Ensure the collet and toolholder are clean and free of chips before seating the shank to maintain runout tolerances. Verify spindle speed and feed rate settings are appropriate for the workpiece material and cutting diameter before engaging the cut.
