Accupro 14797039 Square End Mill 0.016 in 4 Flute Carbide

Product Description

The ACCUPRO 14797039 is a solid carbide square end mill designed for high-precision milling operations in ferrous and non-ferrous metals, hardened steels, and similar difficult-to-machine materials. With a 0.016 inch cutting diameter and a 0.024 inch length of cut, this is a micro-geometry tool built for fine detail work, tight-tolerance slots, and profiling in confined areas. The AlTiN coating provides elevated heat resistance and extended tool life at higher spindle speeds. The micrograin carbide substrate supports the rigidity needed at this diameter to resist deflection and breakage. Machinists and CNC operators in precision machining shops are the primary installers and users of this tool.

This end mill is suited for use in CNC machining centers and high-speed manual mills where micro-end mill work is required. The 0.016 inch diameter makes it appropriate for fine slotting, engraving, and contouring in mold work, aerospace components, medical device manufacturing, and electronics fabrication. The 4-flute configuration supports improved surface finish in finishing passes. The 30-degree helix angle balances chip evacuation with cutting stability at this scale. The 1/8 inch shank diameter allows it to seat in standard collets and micro-tool holders commonly found in production and job shop environments.

Key Features

• 0.016 inch cutting diameter for micro-precision milling applications
• AlTiN coating for heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 4-flute spiral design supports improved surface finish on finishing passes
• 30-degree right-hand helix with right-hand cutting direction for standard CNC setups
• Centercutting capable, supporting plunge entry into workpieces

Compatibility

Designed as an OEM-style replacement or direct-use micro end mill compatible with standard 1/8 inch collets and tool holders used in CNC machining centers and high-speed milling equipment.

Installation Notes

Installation and use of this tool is performed by CNC machinists and tooling specialists. Always ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully into the collet and torque the collet nut to the tool holder manufacturer specification. At this diameter, runout control is critical — use a high-precision collet to minimize deflection and prevent premature tool failure. Follow shop-standard speeds and feeds for micro-diameter carbide end mills appropriate to the workpiece material.
