Sgs 35621 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The SGS 35621 is a solid carbide corner radius end mill designed for precision material removal in non-ferrous metal applications. Built to Series 43CR specifications, it features a 1/2 inch cutting diameter, a 0.1200 inch corner radius, and 3 right-hand spiral flutes with a 38-degree high helix angle. The long-length geometry provides a 2 inch length of cut and a 4 inch overall length, making it well suited for reaching deeper features without sacrificing rigidity. The bright/uncoated finish is appropriate for non-ferrous materials where coating buildup is a concern. This tool is installed and used by machinists and CNC operators in production and job shop environments.

The 35621 is intended for roughing operations on non-ferrous metals such as aluminum, brass, and copper alloys. Its coarse pitch and high helix promote efficient chip evacuation in these materials. The single-end, straight-cylindrical shank fits standard end mill toolholders with a 1/2 inch bore. It is suited for use in vertical machining centers, horizontal mills, and CNC milling machines where toolholder rigidity and accurate runout are maintained.

Key Features

• 0.1200 inch corner radius reduces stress concentration and extends tool life at workpiece edges
• Solid carbide construction provides rigidity and wear resistance in non-ferrous cutting applications
• 38-degree high helix angle promotes smooth cutting action and efficient chip evacuation
• 3-flute, right-hand spiral geometry optimized for coarse-pitch roughing passes
• Long-length design with 2 inch LOC and 4 inch OAL allows reach into deeper pockets and features
• Bright/uncoated finish suited for non-ferrous metals where uncoated carbide performs best

Compatibility

Designed for use with standard end mill toolholders accepting a 1/2 inch straight-cylindrical shank. Intended for non-ferrous metal workpiece materials as specified by the manufacturer primary workpiece material designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before loading the end mill. Secure the shank to the full recommended engagement depth in the toolholder to minimize runout and prevent pullout under cutting loads. Verify spindle speed and feed rate settings are appropriate for the workpiece material and depth of cut before initiating the program.
