Sgs 38109 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The SGS 38109 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. With a 1-inch mill diameter, a 0.0600-inch corner radius, and 4 spiral flutes in a right-hand cutting direction, this tool handles both roughing and finishing passes in a single setup. The short-length geometry features a 1.5-inch length of cut and a 4-inch overall length. The Micrograin carbide substrate and bright uncoated finish make it well-suited for cutting steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. A Weldon flat shank and variable index design contribute to reduced vibration and improved tool life.

This end mill fits into standard end mill toolholders and is appropriate for CNC machining centers and manual milling machines used in job shops, production facilities, and tool-and-die operations. The Series 01C design targets applications involving steel, stainless steel, cast iron, non-ferrous metals, and superalloys where a corner radius profile reduces stress concentration at the cutting edge and extends component life. Hard materials are listed as a secondary workpiece material, expanding its range into hardened steel applications.

Key Features

• 1-inch mill diameter with a 0.0600-inch corner radius for reduced edge chipping on workpiece corners
• 4 spiral flutes with right-hand cutting and right-hand flute direction for standard CNC compatibility
• Micrograin solid carbide construction supports high surface footage and extended tool life
• Variable index flute spacing reduces harmonic chatter during aggressive cuts
• Weldon flat shank provides positive drive engagement in standard side-lock toolholders
• Single-end, short-length geometry rated for both roughing and finishing in one tool

Compatibility

Designed for use with standard end mill toolholders. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. UNSPSC code 27112803.

Installation Notes

Installation is performed by a machinist or CNC operator using a side-lock or Weldon-style toolholder matched to the 1-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after seating the tool, and verify cutting parameters against the workpiece material before initiating a cut. Do not exceed the tool rated depth of cut for the workpiece material class.
