Accupro 14883547 Square End Mill 0.015 in 3 Flute Carbide

Product Description

The ACCUPRO 14883547 is a solid carbide square end mill engineered for precision machining in tight-tolerance applications. With a 0.015 inch cutting diameter and a 0.075 inch length of cut, this tool is built for micro-milling operations where dimensional accuracy is critical. The three-flute, right-hand spiral design promotes efficient chip evacuation while maintaining a stable cut geometry. An AlTiN coating extends tool life in abrasive and high-temperature cutting environments. The 30-degree helix angle balances cutting forces across the flute length. Machinists and tool-and-die professionals working in CNC milling applications will find this end mill suited for ferrous and non-ferrous materials requiring fine feature detail.

This end mill is intended for single-end use in CNC machining centers, vertical mills, and high-speed spindle applications requiring sub-0.020 inch tooling. It is well suited for mold-making, die work, medical component machining, and aerospace detail parts where small-radius features and tight slot tolerances are common. The 1/8 inch shank diameter makes it compatible with standard collet systems and micro-tooling holders used across production and prototype shops.

Key Features

• 0.015 inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for consistent dimensional output
• 3-flute spiral flute geometry promotes chip flow and reduces recutting in confined slots
• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• AlTiN coating improves heat resistance and extends tool life in abrasive cutting conditions
• 30-degree helix angle balances radial cutting forces across the flute length
• Center-cutting capable, allowing plunge entry without a pre-drilled pilot hole

Compatibility

Designed as an OEM-style replacement or direct-use square end mill for CNC milling setups requiring 1/8 inch shank, micro-diameter tooling in standard collet or end mill holders.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The tool should be seated fully in a clean, burr-free collet or end mill holder and torqued per the toolholder manufacturer specifications before spindle engagement. Inspect the shank and collet bore for contamination or runout before securing. Never exceed the recommended depth of cut or feed rate for the given workpiece material and spindle speed.
