Osg HP434-3931 Corner Radius End Mill 10mm 4 Flute Tialn

Product Description

The OSG HP434-3931 is a solid carbide corner radius end mill engineered for high-performance milling across a wide range of workpiece materials. It features a 10 mm cutting diameter, a 1 mm corner radius, and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life in demanding cutting environments. With four flutes, a medium helix angle of 30 degrees, and a centercutting design, this end mill handles both roughing and finishing operations in a single tool. The 22 mm length of cut and 100 mm overall length suit it for general milling work where reach and rigidity are both important. Machinists and CNC programmers specify this tool when surface finish and edge integrity at corners are critical requirements.

The HP434-3931 is suited for use in vertical and horizontal machining centers and CNC milling machines where straight-cylindrical shank toolholders are in use. Its 10 mm shank diameter with h6 tolerance fits standard collet chucks, end mill holders, and shrink-fit toolholders. The right-hand cutting and right-hand flute direction make it compatible with conventional milling center setups. This tool is appropriate for production shops, tool and die operations, and maintenance machining environments where a single end mill must perform across multiple material types.

Key Features

• TiAlN PVD coating improves heat resistance and tool life in steel, stainless, and hard materials
• 1 mm corner radius reduces stress concentration and chipping at workpiece edges
• Centercutting design allows plunge entry without a pre-drilled hole
• Four-flute spiral geometry supports both roughing and finishing in one tool
• Normal pitch and medium helix angle balance chip evacuation with surface finish quality
• Mill diameter tolerance of 0.00 to -0.04 mm ensures consistent fit in close-tolerance applications

Compatibility

Designed for use with standard straight-cylindrical shank toolholders. Rated for cutting steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling and machine tool safety procedures. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated to the recommended engagement depth in the toolholder and that the holder is torqued according to the toolholder manufacturer specifications. Inspect the cutting edges and coating for damage before each use, as carbide end mills are brittle and sensitive to impact.
