Sgs 38087 Corner Radius End Mill 3/4 in 4 Flute Carbide

Product Description

The SGS 38087 is a solid carbide corner radius end mill designed for high-performance material removal and finishing in demanding machining applications. It features a 3/4-inch diameter, a 1-1/2-inch length of cut, and a 0.015-inch corner radius that reduces stress concentrations and extends tool life at the cutting edge. With four right-hand helical flutes in a medium helix configuration and a Weldon flat shank, this end mill delivers consistent chip evacuation and secure tool holding. The micrograin carbide construction provides the hardness and wear resistance required for cutting steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium.

This end mill is suited for both roughing and finishing operations on a wide range of workpiece materials, including hard materials as a secondary application. The short flute length geometry is appropriate for general-purpose milling where rigidity and accuracy are priorities. It mounts in standard end mill holders and is used in CNC machining centers and manual mills across production and toolroom environments. The single-end, centercutting-capable design allows plunge entry where needed.

Key Features

• 0.015-inch corner radius reduces edge chipping and improves surface finish on corners
• Micrograin solid carbide construction for hardness and wear resistance in ferrous and exotic materials
• Four right-hand helical flutes with normal pitch for balanced roughing and finishing performance
• Weldon flat shank for positive engagement and minimal pullout in end mill holders
• Uncoated bright finish suitable for applications where coating compatibility or re-sharpening is a consideration
• Variable index flute spacing reduces harmonic chatter during aggressive cuts

Compatibility

Designed for use with standard end mill holders. Compatible with machining of steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Shank diameter tolerance is h6 for precise holder fit.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before tool changes. Seat the Weldon flat against the set screw in the holder to prevent axial pullout during cutting. Verify runout after installation and before beginning a cut, as excessive runout accelerates wear on a tight-tolerance corner radius tool.
