Accupro 14797178 Square End Mill 0.035 in 3 Flute Carbide

Product Description

The ACCUPRO 14797178 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 0.035-inch cutting diameter and a 0.052-inch length of cut, this tool is engineered for small-feature and micro-milling work where dimensional accuracy is critical. The AlTiN (aluminum titanium nitride) coating provides high heat resistance and extended tool life in ferrous and hard materials. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The micrograin carbide substrate supports rigidity and edge retention at small diameters, making this end mill a reliable choice for close-tolerance work.

This end mill is suited for CNC machining centers, vertical mills, and high-speed machining setups where small-diameter tooling is required. It is used in applications such as slotting, profiling, and contouring in mold and die work, aerospace components, and precision part manufacturing. The extended reach configuration, with a 0.525-inch reach length and a 1/8-inch shank diameter, allows access to deeper features and tighter geometries without sacrificing rigidity. It is installed and used by machinists and CNC operators working with ferrous metals, hardened steels, and similar materials.

Key Features

• 0.035-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• AlTiN coating for superior heat resistance and extended tool life in hard and abrasive materials
• 3 right-hand spiral flutes with a 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide substrate for rigidity and edge retention at micro diameters
• Center-cutting geometry allows direct plunge entry
• Extended reach design with 0.525-inch reach length for deep-feature access

Compatibility

Designed as a standard 1/8-inch shank square end mill compatible with collet chucks, ER collet systems, and end mill holders accepting 1/8-inch shank tooling on CNC machining centers and manual vertical mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Verify that the collet or tool holder is rated for the 1/8-inch shank diameter and that runout is minimized before beginning a cut. Do not exceed the recommended depth of cut for the 0.052-inch length of cut specification. Proper tool projection from the holder should be minimized to maintain rigidity, especially at this diameter.
