Accupro 2500430 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 2500430 is a double-end square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), this tool delivers high hardness and wear resistance across a range of ferrous and non-ferrous materials. It features a 3/16 inch cutting diameter, a 5/16 inch length of cut, and a 60-degree helix angle that promotes aggressive chip evacuation and smooth cutting action. The double-end configuration extends tool life by providing two usable cutting ends. This end mill is sized in the stub length category and is suited for CNC machining centers and manual milling machines alike. It is installed and replaced by machinists and toolroom professionals.

The 2500430 is well suited for slotting, profiling, and light pocket milling in tool steels, stainless steels, aluminum, and other machinable alloys. Its 3-flute geometry balances chip clearance and cutting stability, making it a practical choice for finish passes and moderate material removal in tight-tolerance applications. The stub length classification keeps deflection low at small diameters, which is especially useful when working in confined workpiece features or shallow cavities.

Key Features

• Micrograin solid carbide construction for rigidity and heat resistance
• TiCN coating increases surface hardness and reduces built-up edge
• 60-degree helix angle improves chip flow and cutting efficiency
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill setups
• Center-cutting capable — suitable for plunge entry

Compatibility

Designed as a standard shank end mill compatible with 3/16 inch collets, ER-style collet chucks, and end mill holders used on CNC machining centers and manual vertical mills.

Installation Notes

End mills should be installed by qualified machinists using properly sized collets or tool holders rated for the shank diameter. Always verify runout with an indicator before production cuts. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the recommended depth of cut for the material and tool diameter combination.
