Sgs 33142 Ball End Mill 0.125 in 4 Flute Solid Carbide

Product Description

The SGS 33142 is a solid carbide ball end mill designed for precision milling in demanding metalworking and machining applications. Built to Series 1LB long-length standards, this single-end tool features a 0.125-inch diameter with a 0.75-inch length of cut and a 2.25-inch overall length. The micrograin carbide construction provides the rigidity and edge retention needed for consistent performance across a wide range of workpiece materials. The 4-flute geometry combined with a 30-degree right-hand helix supports efficient chip evacuation and smooth cutting action. It is installed and used by machinists and CNC operators working in job shops, tool rooms, and production machining environments.

The SGS 33142 is suited for milling operations across a broad spectrum of materials, including cast irons, non-ferrous metals, stainless steels, high-temperature alloys, and titanium alloys, corresponding to material codes H, K, M, N, P, and S. The long-series length makes it appropriate for applications requiring extended reach into pockets, slots, or contoured surfaces where a standard-length tool cannot access. Variable index flute spacing helps reduce harmonic vibration during cuts, improving surface finish quality.

Key Features

• 0.125-inch ball end diameter with mill diameter tolerance of +0.000 to -0.002 inches
• 4-flute spiral geometry with 30-degree right-hand helix for efficient chip flow
• Micrograin solid carbide construction for edge retention and rigidity
• Variable index flute spacing reduces chatter and vibration during operation
• Long-series 1LB design with 0.75-inch length of cut and 2.25-inch overall length
• Uncoated finish suitable for a wide range of workpiece materials without coating-compatibility concerns

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 0.125-inch tool holders and collets used in CNC machining centers, manual mills, and high-speed spindles accepting 1/8-inch shank tooling.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder rated for 0.125-inch shank diameter; verify shank seating depth and runout before operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Shank diameter tolerance is +0.00000 to -0.00032 inches, so collet condition and cleanliness directly affect concentricity and tool life. Follow shop-standard feeds, speeds, and depth-of-cut practices appropriate to the workpiece material and machine rigidity.
