Widia 2837501 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The WIDIA 2837501 is a 4-flute solid carbide square end mill designed for high-performance metal removal in demanding machining environments. It carries a 1/2 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length. The tool features a 38-degree helix angle with a right-hand cut and right-hand flute direction, and it is finished with a TiAlN-LW coating that supports elevated cutting temperatures and extended tool life. The Weldon flat shank provides positive retention in standard end mill holders. This tool is intended for use by machinists and CNC operators working in production and job-shop settings.

The 2837501 is engineered for machining steel, stainless steel, cast iron, superalloys, titanium, hard materials, and high-temperature alloys. It belongs to WIDIA Series 4V05, a line built around versatility across ISO material groups P, M, K, S, and H. The regular-length profile and 2 inch reach make it well suited for standard slotting, profiling, and peripheral milling operations where extended reach is not required. It is centercutting, allowing plunge entry into workpiece material.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN-LW coating supports high cutting speeds and thermal stability
• 38-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling
• Weldon flat shank provides secure seating in standard end mill holders
• Right-hand cut and right-hand flute direction for conventional CNC spindle use

Compatibility

Designed for use in standard 1/2 inch end mill holders or collet chucks with Weldon flat accommodation. Suitable for machining ISO material groups P (steel), M (stainless steel), K (cast iron), S (superalloys and titanium), and H (hard materials), as well as high-temperature alloys.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before inserting or removing the tool from the holder. Confirm that the holder bore and Weldon flat setscrew are clean and free of chips before seating the tool. Do not exceed the tool manufacturer-recommended cutting parameters for the target workpiece material and coating grade.
