Sgs 35684 Corner Radius End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The SGS 35684 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal applications. It features a 3/8-inch cutting diameter, a 1-1/2-inch length of cut, and a 0.03-inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in high-cycle operations. The three-flute, right-hand helical geometry promotes efficient chip evacuation. A TiB2 (Ti-NAMITE-B) coating reduces built-up edge and friction when cutting aluminum and other non-ferrous materials. This tool is installed by machinists and toolroom technicians in CNC machining centers and manual mills.

The 35684 is suited for roughing passes in non-ferrous metals such as aluminum, brass, and copper alloys. The long-length configuration, with a 4-inch overall length and a 3/8-inch straight-cylindrical shank, accommodates applications requiring extended reach into deep pockets or cavity features. The coarse pitch and high helix angle support aggressive material removal rates while maintaining part surface quality. It mounts in standard end mill holders compatible with a 3/8-inch shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous cutting
• TiB2 (Ti-NAMITE-B) coating reduces friction and built-up edge on aluminum and non-ferrous alloys
• 0.03-inch corner radius reduces edge chipping and stress concentration at the tool tip
• Three-flute, right-hand helical geometry promotes efficient chip evacuation
• Long-length series with 4-inch OAL for extended-reach applications
• Coarse pitch, high helix angle optimized for roughing passes

Compatibility

Designed for use with standard end mill holders accepting a 3/8-inch straight-cylindrical shank. Intended for primary use in non-ferrous metal workpiece materials per Series 43CR application guidelines.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the end mill holder to the manufacturer-recommended engagement depth before tightening. Confirm spindle direction is set to right-hand rotation before operation. Inspect the cutting edges and corner radius for chips or wear before each use, and replace the tool if edge integrity is compromised.
