Accupro 14883540 Square End Mill 0.04 in 3 Flute Altin

Product Description

The ACCUPRO 14883540 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.04-inch cutting diameter and three flutes, this single-end tool delivers efficient chip evacuation and a clean finish in tight-tolerance work. The AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life during high-speed cutting. The 30-degree helix angle promotes smooth cutting action and reduced cutting forces. Right-hand cut and right-hand flute direction follow standard CNC and manual milling conventions. Micrograin carbide construction supports consistent edge integrity across a range of workpiece materials.

This end mill is suited for small-diameter finish milling, slotting, and profiling in ferrous metals, stainless steels, and high-temperature alloys where heat buildup is a concern. The AlTiN coating makes it a practical choice for dry or near-dry cutting environments. The 1/8-inch shank diameter fits standard collets and toolholders used on CNC machining centers and manual mills handling small-diameter tooling. The centercutting geometry allows for plunge entry where required in the operation.

Key Features

• 0.04-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches
• AlTiN coating for heat resistance and extended tool life in hard or abrasive materials
• Micrograin solid carbide substrate for edge stability and wear resistance
• 3 flutes with spiral flute type and 30-degree right-hand helix for efficient chip flow
• Centercutting design allows plunge milling capability
• 1/8-inch shank with tight shank diameter tolerance of -0.0001 / -0.0003 inches

Compatibility

Designed for use in standard 1/8-inch collets and toolholders on CNC machining centers and manual milling machines requiring small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized, clean collet or toolholder before operation. Verify runout after installation, as small-diameter end mills are sensitive to even minor collet contamination or wear. Follow shop-standard speeds and feeds for the workpiece material and coating type.
