Accupro 14796957 Square End Mill 0.043 in 4 Flute Altin Carbide

Product Description

The ACCUPRO 14796957 is a solid micrograin carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. At 0.043 inches in diameter with a 0.129-inch length of cut, this is a small-diameter tool built for fine detail work, slot milling, and profiling in tight geometries. The AlTiN coating provides high heat resistance, extending tool life in harder materials and dry-cutting applications. With a 30-degree helix angle and four flutes in a right-hand spiral configuration, the tool delivers efficient chip evacuation and a smooth finish. Machinists and toolmakers running CNC machining centers or manual mills install this tool when tight tolerances and hard material demands call for a reliable, coated carbide solution.

This end mill suits small-diameter finish and semi-finish milling operations in tool and die work, mold making, aerospace components, and precision part manufacturing. The 0.125-inch shank diameter is compatible with standard 1/8-inch collets and tool holders. With a 1.5-inch overall length and center-cutting capability, it can be used for plunge entry as well as peripheral milling. The tool is intended for single-end use and is not designed for extended-reach applications.

Key Features

• 0.043-inch mill diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for consistent fit
• AlTiN coating for elevated heat resistance and extended tool life in harder materials
• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• Four-flute right-hand spiral design promotes efficient chip evacuation and surface finish quality
• 30-degree helix angle balances cutting force and finish across a range of materials
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole

Compatibility

Designed for use with standard 1/8-inch collet tool holders and CNC or manual milling setups requiring a small-diameter square end mill. Suitable for slot milling, profiling, and finish milling in ferrous alloys, stainless steel, and hard materials where an AlTiN-coated carbide tool is specified.

Installation Notes

This tool is installed by machinists and toolroom technicians using a calibrated collet or end mill holder matched to the 0.125-inch shank. Ensure the tool holder is clean and free of chips before seating the shank to the full recommended insertion depth. Set spindle speeds and feed rates according to the workpiece material and the manufacturer's speed-and-feed data for AlTiN-coated carbide tools at this diameter. Inspect the cutting edges under magnification before use, as small-diameter carbide tools are susceptible to chipping if mishandled.
