Sgs 35688 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The SGS 35688 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal machining applications. It features a 1/2 inch mill diameter, a 0.015 inch corner radius, and three right-hand helical flutes with a coarse pitch and high helix angle of 38 degrees. The cutting end carries a TiB2 (Ti-NAMITE-B) coating, which reduces friction and extends tool life in aluminum, copper, brass, and similar workpiece materials. This is a single-end, center-cutting tool intended for use in CNC machining centers and manual mills with compatible end mill holders. Installation and operation are performed by machinists and tool and die professionals.

The SGS 35688 is built for roughing operations on non-ferrous metals, including aluminum alloys and other materials classified under primary workpiece material code N. Its short flute length and straight-cylindrical shank make it well-suited for rigid setups in standard end mill holders. The 5/8 inch length of cut and 3 inch overall length position it for slots, pockets, and profiling passes where corner radius geometry is required to reduce stress concentrations at part features.

Key Features

• 0.015 inch corner radius with a tolerance of -0.0020 to 0.0000 inches for consistent edge geometry
• TiB2 (Ti-NAMITE-B) coating optimized for non-ferrous metal cutting
• Three right-hand helical flutes with 38-degree high helix angle for efficient chip evacuation
• Solid carbide construction for rigidity and wear resistance in roughing applications
• Straight-cylindrical shank with h6 tolerance for secure end mill holder fitment
• Single-end, center-cutting design compatible with plunge and ramp entry cuts

Compatibility

Designed for use with standard end mill holders. Primary workpiece material is non-ferrous metal (material code N). Series 43CR designation applies to SGS corner radius tooling in this geometry family.

Installation Notes

Installation is performed by machinists using compatible end mill holders and appropriate set screws or collet systems. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank diameter and holder bore tolerance before seating the tool. Follow machine tool manufacturer runout specifications and confirm the corner radius orientation is correct before initiating a cut.
