Sgs 38003 Corner Radius End Mill 1/8 in 4 Flute Carbide

Product Description

The SGS 38003 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous materials in metalworking and machining applications. It features a 1/8 inch diameter cutting edge with a 0.02 inch corner radius, 4 helical flutes with a 30-degree helix angle, and a 1/2 inch length of cut. The uncoated micrograin carbide construction delivers consistent performance across roughing and finishing operations. The single-end, right-hand cutting configuration suits vertical and horizontal milling setups where close-tolerance profiling and edge finishing are required.

This end mill is appropriate for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. With a 1/8 inch shank diameter and 1-1/2 inch overall length, it fits standard end mill holders used in CNC machining centers and manual milling machines. The corner radius geometry reduces stress concentration at the cutting edge, making it well suited for slot milling, profile milling, and contour work where edge life matters.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance across a broad material range
• 0.02 inch corner radius reduces edge chipping and extends tool life in profiling cuts
• 4 right-hand helical flutes with 30-degree helix angle for efficient chip evacuation
• Uncoated finish suitable for dry or wet cutting conditions without coating adhesion concerns
• Variable index flute spacing reduces harmonic vibration during aggressive material removal
• Compatible with end mill holders via straight-cylindrical shank with h6 shank diameter tolerance

Compatibility

Designed for use with standard end mill holders. Suitable for CNC machining centers and manual mills accepting a 1/8 inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metal, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by qualified machinists following standard tooling change procedures. Power down and lock out the machine spindle before changing tooling. Seat the shank fully in the end mill holder and verify runout with a dial indicator before beginning a cut. Follow the machine tool manufacturer guidelines for speed and feed recommendations based on workpiece material and depth of cut.
