Accupro 14883527 Square End Mill 0.04 in 3 Flute Carbide

Product Description

The ACCUPRO 14883527 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. It features a 0.04-inch cutting diameter and a 13/64-inch (0.200-inch) length of cut, making it well suited for fine detail work, slotting, and profiling in tight geometries. The three-flute configuration balances chip evacuation with cutting rigidity. A 30-degree right-hand spiral helix angle promotes smooth cutting action and reduces chatter. Machinists and tool-and-die professionals working with CNC mills or manual vertical mills will find this tool appropriate for high-precision applications requiring tight tolerances.

This end mill is used in applications that demand fine feature resolution, such as die cavities, mold work, micro-slotting, and detailed profile cutting. Its 0.125-inch shank diameter fits standard ER collets and end mill holders common to both benchtop and production CNC milling equipment. The single-end, centercutting design allows both plunge and contour cutting. The bright uncoated finish makes it suitable for use with cutting fluid on ferrous and non-ferrous materials where coating adhesion or heat buildup is not the primary concern.

Key Features

• 0.04-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for consistent, repeatable results
• Three right-hand flutes with a 30-degree helix angle for efficient chip removal and reduced cutting forces
• Micrograin solid carbide construction for improved wear resistance and edge retention compared to high-speed steel
• Centercutting geometry enables direct plunge milling without pre-drilling
• Bright/uncoated finish compatible with a wide range of cutting fluids and work materials
• 2.5-inch overall length with a 0.125-inch shank diameter for standard collet compatibility

Compatibility

Designed as a standard-fitment replacement or addition for CNC and manual milling setups that accept a 1/8-inch shank diameter end mill via ER collet, shrink-fit, or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify collet size matches the 0.125-inch shank diameter and that the tool is seated to the recommended minimum engagement depth per the holder manufacturer's guidelines. Do not exceed the tool's rated depth of cut or feed rates for the work material being machined.
