Sgs 30043 Ball End Mill 0.2031 in 4 Flute Solid Carbide

Product Description

The SGS 30043 is a single-end ball end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cut profiles. The tool measures 0.2031 inches in diameter with a 0.625 inches length of cut and a 2.5 inches overall length. A 30-degree helix angle promotes smooth chip evacuation, while the AlTiN coating provides thermal resistance and extended tool life at elevated cutting speeds. The variable index geometry reduces chatter and improves surface finish. This end mill is installed and operated by machinists and CNC programmers working on production and prototype work.

The SGS 30043 is suited for milling operations requiring a ball-nose profile, including contour milling, slotting, and 3D surface work. The 4-flute configuration balances chip clearance and rigidity, making it appropriate for semi-finishing and finishing passes. Primary workpiece material compatibility codes H, K, M, N, P, and S indicate suitability across a broad range of ferrous and non-ferrous metals, including hardened steels, cast iron, stainless steel, non-ferrous alloys, steel, and heat-resistant superalloys. The 1/4-inch shank fits standard collets and toolholders common in CNC machining centers and manual mills.

Key Features

• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Mill diameter tolerance of +0.000 to -0.002 inches for precise fit and finish
• Single-end ball nose profile suited for contour and 3D surface milling

Compatibility

Compatible with workpiece material codes H, K, M, N, P, and S, covering hardened steels, cast iron, stainless steel, non-ferrous alloys, steel, and heat-resistant superalloys. Fits standard 1/4-inch collets and toolholders. Part of the SGS Series 1B end mill line.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle and toolholder are fully powered down and at rest before changing or measuring the tool. Verify collet condition and shank seating before tightening to prevent runout. Follow machine manufacturer torque specifications for collet nut tightening and confirm RPM and feed rate settings match the workpiece material before beginning a cut.
