Sgs 38133 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The SGS 38133 is a solid carbide corner radius end mill designed for precision milling in demanding industrial and machining environments. Built for single-end use, it features a 1/2 inch mill diameter, a 1 inch length of cut, and a 0.02 inch corner radius that helps reduce stress concentrations and extend tool life at part edges. The TiCN coating improves surface hardness and wear resistance, making this end mill well-suited for both roughing and finishing passes. Four helical flutes with a right-hand cutting direction provide efficient chip evacuation. A Weldon flat shank ensures positive engagement in end mill holders.

This end mill is intended for use in CNC machining centers and manual mills where close-tolerance work on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium is required. It is also rated for secondary use on hard materials. The short length type and 3 inch overall length make it a practical choice for general-purpose milling applications where rigidity and reach are balanced. It is sized for end mill holders with a 1/2 inch bore and Weldon flat retention.

Key Features

• 0.02 inch corner radius reduces edge chipping and stress concentration at part corners
• TiCN coating provides increased surface hardness and wear resistance for extended tool life
• Solid carbide micrograin construction maintains dimensional stability under high cutting forces
• Four right-hand helical flutes support efficient chip removal during roughing and finishing
• Weldon flat shank design ensures positive drive and secure clamping in end mill holders
• Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials

Compatibility

Designed for use with standard end mill holders accepting a 1/2 inch shank with Weldon flat engagement. Suitable for CNC and manual milling operations across the material grades listed in the specifications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the Weldon flat shank fully into the holder and torque set screws to the holder manufacturer's specification. Verify runout with a dial indicator before beginning cuts, and confirm appropriate speeds and feeds for the workpiece material prior to operation.
