Accupro 14797038 Square End Mill 0.014 in 4 Flute Altin

Product Description

The ACCUPRO 14797038 is a solid carbide square end mill designed for precision machining of tight-tolerance features in ferrous and non-ferrous materials. With a 0.014-inch cutting diameter and a 0.021-inch length of cut, this tool is built for micro-milling applications where dimensional accuracy is critical. The AlTiN coating delivers high heat resistance and wear life at elevated cutting speeds. A 30-degree helix angle promotes efficient chip evacuation in confined cuts. Machinists and tool-and-die professionals use this end mill where fine detail and reliable tool life are required.

This end mill is suited for CNC milling operations requiring micro-scale precision, including die cavities, mold features, and fine-detail engraving work. Its 1/8-inch shank diameter fits standard ER collet chucks and micro-tool holders. The right-hand cutting and right-hand flute direction are compatible with conventional CNC machining center spindle rotation. Single-end construction with a 1.5-inch overall length provides adequate reach for shallow pocket and surface work while maintaining rigidity.

Key Features

• 0.014-inch cutting diameter for micro-precision milling applications
• AlTiN coating for elevated heat resistance and extended tool life
• 4-flute, right-hand spiral design for smooth finish and chip evacuation
• 30-degree helix angle reduces cutting forces in fine-feature work
• Centercutting geometry allows plunge entry
• Micrograin solid carbide substrate for rigidity and edge retention at small diameters

Compatibility

Designed as a direct-fit tool for CNC machining centers and milling machines equipped with 1/8-inch collet or micro-tool holder systems accepting standard straight-shank end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully into the collet to the recommended depth and torque the collet nut per the tool holder manufacturer specification. At 0.014-inch diameter, this tool is highly susceptible to breakage from runout, excessive feed rate, or improper clamping — verify collet condition and runout before cutting.
