Accupro 12181598 Square End Mill 5/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181598 is a solid carbide square end mill designed for precision milling in metal and alloy applications. With a 5/32-inch (0.1563-inch) cutting diameter and a 40-degree helix angle, it is built for efficient chip evacuation and smooth cutting performance. The AlTiN coating provides heat resistance and extended tool life in high-temperature cutting environments. This is a centercutting, right-hand cut, right-hand flute tool with a spiral flute geometry. It is a stub-length end mill, suited for rigid setups where minimal deflection is critical. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.

This end mill is intended for use in ferrous and non-ferrous metal cutting, including hardened steels and high-temp alloys where the AlTiN coating provides thermal protection. The stub-length configuration with a 3/8-inch length of cut and 2-inch overall length makes it well suited for shallow-pocket milling, slotting, and profiling operations where tool rigidity is a priority. It fits standard 3/16-inch collets or tool holders and is packaged as a single unit.

Key Features

• AlTiN finish for heat resistance and extended tool life in demanding cuts
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows plunge entry into the workpiece
• Micrograin solid carbide construction for rigidity and wear resistance
• Stub-length design minimizes deflection in tight-tolerance setups
• Right-hand cut and right-hand flute configuration for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills using a 3/16-inch collet or compatible tool holder accepting a 0.1875-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Secure the shank fully in the collet or tool holder to the recommended grip depth before tightening. Verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Never exceed the tool manufacturer's recommended depth of cut or lateral engagement for the given diameter.
