Sgs 38219 Corner Radius End Mill 1/4 in 2 Flute Carbide

Product Description

The SGS 38219 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. With a 1/4-inch mill diameter and a 0.015-inch corner radius, this tool produces a controlled edge break on milled features, reducing stress concentrations and improving surface finish. The 2-flute, right-hand helical geometry with a 30-degree helix angle promotes efficient chip evacuation during roughing passes. Weighing 0.2 pounds, this single-end, straight-shank tool is built for rigidity and precision. It is installed and operated by machinists and CNC tooling professionals working with milling machines and machining centers.

This end mill is suited for roughing operations across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, with secondary capability in hard materials. The uncoated, bright finish micrograin carbide construction makes it appropriate for applications where coating interaction with the workpiece is a concern. Typical install scenarios include peripheral milling, slotting, and profiling where a controlled corner radius is required. It is compatible with standard end mill holders.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in ferrous and non-ferrous applications
• 0.015-inch corner radius reduces edge chipping and stress concentration at milled corners
• 2-flute, right-hand cut, 30-degree medium helix promotes chip evacuation during roughing
• Uncoated bright finish suitable for a wide range of base materials without coating compatibility concerns
• Single-end, centercutting-capable geometry supports plunge and ramp entry
• Straight cylindrical shank with h6 shank diameter tolerance for precise holder fit

Compatibility

Designed for use with standard end mill holders. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before loading or removing the tool from the holder. Verify holder runout and clamp torque per the holder manufacturer specifications before initiating a cut. Do not exceed the rated length of cut of 3/4 inch to avoid deflection or tool breakage during operation.
