Sgs 38103 Corner Radius End Mill 1in 4 Flute Solid Carbide

Product Description

The SGS 38103 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1 inch cutting diameter, a 1.5 inch length of cut, and a 0.0200 inch corner radius that reduces stress concentrations at part corners and extends tool life compared to sharp-edge end mills. The four-flute, right-hand spiral geometry supports both roughing and finishing passes in a single setup. The Weldon flat shank seats securely in standard end mill toolholders. Machinists and CNC operators running production or job-shop work install this tool in vertical mills, machining centers, and CNC knee mills.

This end mill is built for cutting steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its micrograin carbide substrate and bright uncoated finish make it well-suited for applications where coating compatibility with certain materials or cutting fluids is a concern. The Series 01C short-length configuration provides rigidity in slotting, profiling, and peripheral milling operations where deflection control is critical.

Key Features

• 1 inch cutting diameter with 0.0200 inch corner radius for reduced notch stress
• 4-flute right-hand spiral design supports roughing and finishing in one tool
• Micrograin solid carbide substrate for hardness and wear resistance in ferrous and superalloy cuts
• Weldon flat shank for positive drive retention in standard end mill toolholders
• Variable index geometry reduces harmonic chatter during aggressive cuts
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials

Compatibility

Designed for use with standard end mill toolholders accepting a 1 inch Weldon flat shank. Suitable for vertical machining centers, CNC mills, and manual knee mills running steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before tooling changes. Seat the Weldon flat fully against the toolholder set screw and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, and confirm spindle speed and feed rate match published data for the workpiece material and depth of cut.
