Sgs 31434 Ball End Mill 0.3125 in 4 Flute Solid Carbide

Product Description

The SGS 31434 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous metals, high-temperature alloys, and composite materials. Built from micrograin carbide stock, this double-end mill delivers a 0.3125-inch cutting diameter with a 0.5-inch length of cut and a 30-degree helix angle that promotes efficient chip evacuation and stable cutting action. With four flutes in a right-hand spiral configuration, it is suited for finishing passes and light profiling where dimensional accuracy and surface finish are the priority. Machinists and tool-and-die shops rely on this geometry for contouring and cavity work in CNC machining centers.

The SGS 31434 is intended for use across a broad range of workpiece materials, covering material code designations H, K, M, N, P, and S — which correspond to hardened steels, cast irons, stainless steels, non-ferrous materials, carbon and alloy steels, and high-temperature superalloys. The double-end design extends tool life by providing a second usable cutting end, making it a practical choice for production environments where tooling cost per part is tracked. Typical applications include 3D contouring, slot milling, and profiling on vertical and horizontal machining centers running steel, aluminum, titanium, and nickel-based alloy workpieces.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• Four-flute, right-hand spiral geometry for smooth chip flow and fine surface finishes
• 30-degree helix angle balances cutting forces and chip evacuation across multiple materials
• Double-end design provides two cutting edges per tool, lowering cost per cutting edge
• Stub length classification with 2.5-inch overall length for reduced overhang and improved rigidity
• Uncoated finish suitable for use with cutting fluids or dry in non-ferrous materials

Compatibility

Compatible with workpiece material codes H, K, M, N, P, and S as designated by the supplier, covering hardened steels, cast irons, stainless steels, non-ferrous alloys, carbon and alloy steels, and high-temperature superalloys. Belongs to SGS Series 14B.

Installation Notes

Installation is performed by qualified machinists following standard CNC tooling procedures. Secure the 0.3125-inch shank in a compatible collet or end mill holder, ensuring runout is within acceptable limits before engaging the cut. Verify spindle speed and feed rate settings match the workpiece material and depth of cut before starting. Inspect the cutting edges before each use and replace the tool at the first sign of chipping or excessive wear to prevent workpiece damage.
