Accupro 14883440 Square End Mill 0.09 in 3 Flute Altin

Product Description

The ACCUPRO 14883440 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous metals. It features a 0.09-inch cutting diameter with a 29/64-inch (0.45-inch) length of cut and a 3-flute, right-hand spiral configuration. The AlTiN coating provides heat resistance and extends tool life in high-speed cutting applications. With a micrograin carbide substrate and 30-degree helix angle, this end mill delivers sharp chip evacuation and stable cutting performance in both slotting and profiling operations. It is a single-end tool mounted on a 1/8-inch shank with a 2.5-inch overall length.

This end mill is suited for CNC milling operations in job shops, tool rooms, and production machining environments. Its small diameter and AlTiN coating make it appropriate for detailed profile work, slot milling, and finishing passes on hardened steels, stainless, and titanium alloys. The centercutting geometry allows plunge entry where needed. Typical users include CNC machinists and toolroom operators working with tight-tolerance components in aerospace, medical device, and general metalworking applications.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for high-temperature performance and extended tool life
• 3-flute, right-hand spiral geometry with 30-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Single-end configuration on a 1/8-inch shank for use in standard collet holders
• Mill diameter tolerance of +0.0000 / -0.0010 inches for consistent sizing

Compatibility

Designed for use in CNC machining centers and manual mills equipped with ER or similar collet systems accepting a 1/8-inch shank. Part of the ACCUPRO ASQSC3-AT-CC-30H series of AlTiN-coated square end mills.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Secure the shank firmly in a collet or end mill holder torqued to the machine manufacturer's specification before operation. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Do not exceed the recommended depth of cut for the listed length-of-cut range of 0.30 to 0.50 inches.
