Sgs 40106 Ball End Mill 0.0394 in 4 Flute Solid Carbide

Product Description

The SGS 40106 is a solid carbide ball end mill designed for precision milling operations across a wide range of workpiece materials. With a 0.0394-inch (1.00 mm) mill diameter and a 0.158-inch length of cut, this tool is built for small-diameter, high-accuracy work where tool rigidity and edge quality are critical. The 4-flute, single-end geometry with a 30-degree helix angle supports efficient chip evacuation and stable cutting action. Manufactured from micrograin carbide, the 40106 delivers consistent performance in demanding cutting environments. Machinists and tool-and-die professionals working on tight-tolerance features will find this tool suited to their requirements.

The SGS 40106 is well-suited for milling small contoured features, slots, and profiling passes on parts made from a broad spectrum of materials including cast iron, non-ferrous metals, steel, stainless steel, heat-resistant alloys, and titanium. Its 1.5-inch overall length and 3.00 mm shank diameter make it compatible with standard small-bore collet systems. The right-hand cutting and right-hand flute direction follow conventional CNC and manual milling machine setups. This tool is a single-end design intended for use in production and job-shop environments where repeatable dimensional accuracy is required.

Key Features

• 0.0394-inch (1.00 mm) ball end diameter for small-feature precision milling
• 4-flute spiral geometry with variable index for reduced harmonic vibration
• 30-degree helix angle supports chip flow and surface finish quality
• Micrograin solid carbide construction for edge retention and rigidity
• Uncoated finish suitable for a wide variety of material groups including steel, stainless, non-ferrous, and superalloys
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

The SGS 40106 is a Series 1B regular-length ball end mill compatible with standard 3.00 mm shank collet chucks and tool holders on CNC machining centers and manual milling machines configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the collet or tool holder. Verify collet bore size matches the 3.00 mm shank diameter and that the tool is seated to the correct gauge length before running. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material being cut.
