Sgs 30516 Ball End Mill 0.125 in 3 Flute Solid Carbide

Product Description

The SGS 30516 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.125 inch (1/8 inch) mill diameter and a 0.5 inch length of cut, this single-end tool is built for tight-tolerance work in a wide range of workpiece materials. The micrograin carbide construction delivers hardness and edge retention that high-speed steel tools cannot match. A 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. The uncoated finish makes this tool a straightforward choice when coating is not required for the application at hand. Machinists and toolroom professionals are the primary users of this end mill.

This end mill is suited for slotting, profiling, and contouring operations that require a ball-nose geometry to produce a radiused floor or complex 3D surface. The 3-flute configuration balances chip clearance and rigidity, making it effective in both roughing passes and light finishing cuts. The 1/8 inch shank diameter fits standard collet chucks and end mill holders commonly found on CNC machining centers and manual knee mills. The right-hand cutting and right-hand spiral flute direction are consistent with conventional milling center spindle rotation. Compatible workpiece material codes include H, K, M, N, P, and S, covering a broad range of ferrous and non-ferrous alloys.

Installation Notes

This tool is installed by machinists in CNC or manual milling setups. Ensure the spindle is fully stopped and the machine is powered down before changing or seating the tool in the collet. Verify runout with a dial indicator after seating to protect the cutting edge and maintain dimensional accuracy. Follow the machine tool manufacturer guidelines for feed rate, spindle speed, and depth of cut for the specific workpiece material being machined.
