Osg HP434-2363 Corner Radius End Mill 6 Mm 4 Flute Tialn

Product Description

The OSG HP434-2363 is a solid carbide corner radius end mill designed for precision milling in demanding material applications. Part of the HP434 series, it features a 6 mm cutting diameter, 1.50 mm corner radius, and a 4-flute geometry that supports both roughing and finishing operations in a single tool. The TiAlN PVD coating provides thermal resistance and extended tool life when machining at elevated cutting speeds. A 35-degree medium helix angle promotes efficient chip evacuation while maintaining cutting stability. This end mill is intended for use in CNC machining centers and manual mills by machinists and toolroom professionals.

The HP434-2363 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its centercutting capability allows direct plunge entry into workpieces. The straight-cylindrical shank mounts directly into standard toolholders and collet chucks. Typical applications include contour milling, slot milling, and profile work in aerospace, die-and-mold, and general metalworking environments where corner integrity and surface finish are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard materials
• TiAlN PVD coating extends tool life in high-temperature cutting environments
• 1.50 mm corner radius reduces stress concentration and improves corner durability
• 4-flute, right-hand spiral design supports roughing and finishing in one pass
• Centercutting geometry enables direct plunge entry without pre-drilling
• Normal pitch, no chipbreaker — optimized for clean surface finish at regular feed rates

Compatibility

Designed for use with standard toolholders and collet chucks accepting a 6 mm straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metal, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).

Installation Notes

Installation is performed by machinists or toolroom technicians using a compatible toolholder and collet system. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Verify shank seating depth and runout with a dial indicator before initiating a cut. Consult the machine tool manufacturer guidelines and applicable shop safety procedures for spindle speed and feed rate selection.
