Sgs 30356 Ball End Mill 0.4375 in 2 Flute Solid Carbide

Product Description

The SGS 30356 is a single-end ball end mill designed for precision milling operations across a wide range of workpiece materials. Built from micrograin solid carbide, it delivers consistent edge retention and dimensional accuracy in demanding cutting environments. The tool measures 0.4375 inches in diameter with a 1 inch length of cut and a 2.75 inch overall length. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With a right-hand cutting and right-hand flute direction, the 30356 suits standard spindle setups used by machinists and tool-and-die professionals on CNC and manual milling machines.

This ball end mill is suited for contouring, profiling, and slotting operations in ferrous and non-ferrous metals including cast iron, aluminum, titanium alloys, stainless steel, heat-resistant alloys, and plastics. The Series 3B designation indicates a regular-length configuration appropriate for general-purpose milling where extended reach is not required. The uncoated finish makes it a versatile choice when coating compatibility with specific cutting fluids or workpiece materials is a consideration.

Key Features

• Micrograin solid carbide construction for superior hardness and edge stability
• 0.4375 inch ball diameter with tight mill diameter tolerance of +0.000 to -0.002 inches
• 30-degree spiral helix angle for efficient chip flow and reduced thermal load
• 2-flute geometry optimized for slotting and profiling in a broad material range
• Single-end design with 7/16 inch shank and shank diameter tolerance of +0.00000 to -0.00035 inches
• Uncoated finish compatible with a wide variety of cutting fluid chemistries

Compatibility

Designed as an OEM-style replacement and direct-fit solid carbide ball end mill for standard 7/16 inch collet or end mill holder setups on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool. Use a properly sized collet or end mill holder that matches the 7/16 inch shank diameter to prevent runout. Verify tool projection and reach before beginning any cutting operation.
