Accupro 14883539 Square End Mill 0.05 in 3 Flute Carbide

Product Description

The ACCUPRO 14883539 is a solid carbide square end mill designed for precision milling operations in metal and alloy workpieces. With a 0.05-inch cutting diameter, 3 spiral flutes, and a 30-degree right-hand helix, this tool delivers efficient chip evacuation and clean edge geometry on small-diameter work. The micrograin carbide substrate supports cutting hardness and wear resistance, while the AlTiN coating adds thermal protection during high-speed or dry cutting applications. At 2.5 inches overall length with a 1/8-inch shank, this end mill is sized for CNC machining centers and manual mills where a compact, single-end tool is required. Machinists and tool-and-die professionals install and operate this tool.

This end mill is suited for small-feature milling, slotting, and profiling in ferrous and non-ferrous materials. The centercutting design allows plunge entry, expanding its use in pocketing operations. With a 19/64-inch length of cut and right-hand cutting and flute direction, it is a standard choice for precision machining shops running detailed contour or slot work on CNC equipment. The AlTiN coating makes it particularly well-suited for hardened steels and stainless alloys where heat buildup is a concern.

Key Features

• 0.05-inch cutting diameter with micrograin solid carbide construction for rigidity and edge retention
• 3 right-hand spiral flutes at a 30-degree helix angle for efficient chip removal
• AlTiN coating provides high-temperature resistance and extended tool life in ferrous materials
• Centercutting geometry allows direct plunge entry into workpieces
• 1/8-inch shank diameter compatible with standard collet systems
• Single-end design with 19/64-inch length of cut for small-feature work

Compatibility

Designed as an OEM-style replacement or direct-use tooling for CNC machining centers and manual milling machines equipped with collet systems accepting a 1/8-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. The machine spindle must be fully stopped and locked out before inserting or removing the end mill from the collet or tool holder. Verify collet size matches the 1/8-inch shank before tightening. Follow the machine manufacturer guidelines for runout tolerance and tool projection to avoid deflection on this small-diameter tool.
