Sgs 38091 Corner Radius End Mill 3/4 in 4-flute Carbide

Product Description

The SGS 38091 is a solid carbide corner radius end mill designed for high-performance milling in demanding shop environments. It features a 3/4-inch mill diameter, 1-1/2-inch length of cut, and a 0.03-inch corner radius that reduces stress concentrations at the bottom of a cut and extends tool life. The 4-inch overall length and Weldon flat shank make it compatible with standard end mill holders. With 4 right-hand helical flutes and a medium helix angle, it handles both roughing and finishing operations. This tool is suited for machinists and toolroom operators working on steel, stainless, cast iron, non-ferrous metals, superalloys, and titanium.

The SGS 38091 fits production and job-shop environments where a single tool must transition between stock removal and finish passes. The bright, uncoated micrograin carbide construction performs well across a range of workpiece materials including hard materials. Its variable index flute spacing helps suppress chatter during aggressive cuts. This end mill is a single-end tool, so sharpening or reconditioning would be performed on the cutting end only.

Key Features

• 0.03-inch corner radius reduces edge chipping and stress risers at the base of the cut
• Micrograin solid carbide substrate for extended wear resistance and edge retention
• 4 right-hand helical flutes with variable index for chatter suppression
• Weldon flat shank ensures positive drive in end mill holders
• Bright uncoated finish suitable for a wide range of workpiece materials including superalloys and titanium
• Single-end, centercutting design supports both plunge and peripheral milling operations

Compatibility

Designed for use with standard end mill holders accepting a 3/4-inch Weldon flat shank. Suitable for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per SGS Series 01C application guidelines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Power down and lock out the spindle before inserting or removing the tool from the holder. Verify the Weldon flat is properly engaged with the set screw in the holder before operation. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material being cut.
