Sgs 30502 Ball End Mill 0.0156 in 3 Flute Solid Carbide

Product Description

The SGS 30502 is a single-end ball end mill designed for precision milling in tight geometries and contoured surfaces. Built from micrograin solid carbide, it features a 0.0156-inch (1/64-inch) cutting diameter and a 0.0313-inch (1/32-inch) length of cut, making it well suited for fine detail work, slotting, and profiling in small-feature applications. The 3-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining rigidity at small diameters. The uncoated finish is matched to a broad range of workpiece materials. This tool is used by machinists and toolroom professionals running CNC milling centers.

The SGS 30502 Series 5B end mill is intended for use on CNC machining centers where small-diameter, high-precision cuts are required. Its material compatibility codes cover hardened steels, cast irons, stainless steels, non-ferrous metals, carbon and alloy steels, and superalloys (material grade codes H, K, M, N, P, and S). The 1/8-inch shank diameter fits standard collets commonly found in CNC and manual milling setups. With a 1.5-inch overall length and regular length classification, it is appropriate for shallow-to-moderate reach applications where tool deflection must be minimized.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention at miniature diameters
• 0.0156-inch ball cutting diameter with a mill diameter tolerance of +0.000 to -0.002 inches
• 3-flute, right-hand spiral flute design with 30-degree helix angle for efficient chip flow
• Uncoated finish compatible with a wide range of ferrous and non-ferrous workpiece materials
• Single-end configuration with a 1/8-inch shank and tight shank diameter tolerance of +0.00000 to -0.00032 inches
• Series 5B, regular length at 1.5 inches OAL for stable, low-deflection performance

Compatibility

Designed for use in CNC and manual milling machines accepting a 1/8-inch shank collet. Suitable for workpiece material codes H (hardened steel), K (cast iron), M (stainless steel), N (non-ferrous), P (carbon and alloy steel), and S (superalloys) as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet. Seat the shank fully and evenly in the collet to the manufacturer-recommended grip length to prevent runout at this small diameter. At 0.0156-inch diameter, feed rates and depths of cut must be set conservatively to avoid tool breakage; consult published SGS Series 5B cutting data for starting parameters.
