Sgs 30520 Ball End Mill 0.1563 in 3 Flute Solid Carbide

Product Description

The SGS 30520 is a solid carbide ball end mill designed for precision milling in a wide range of materials. With a 0.1563-inch (5/32-inch) mill diameter and three spiral flutes, it delivers smooth cutting action and efficient chip evacuation in demanding machining operations. The 30-degree helix angle balances cutting forces and surface finish quality. Built from micrograin solid carbide, this end mill holds tight tolerances and resists wear during high-speed metal removal. It is a single-end tool with right-hand cutting and right-hand flute direction, suited for use on CNC machining centers and manual milling equipment.

The SGS 30520 is appropriate for milling ferrous metals, nonferrous metals, high-temperature alloys, and plastics, covering primary workpiece material codes H, K, M, N, P, and S. Its regular-length Series 5B design makes it a practical choice for contour milling, slot milling, and profiling operations where a small-diameter ball nose profile is required. No extended reach or coolant-through feature is present, so it fits standard tool holders without additional adapters.

Key Features

• 0.1563-inch (5/32-inch) ball nose diameter for fine contour and profile work
• Three spiral flutes with 30-degree helix for balanced cutting and chip flow
• Micrograin solid carbide construction for wear resistance and dimensional stability
• Uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut, right-hand flute, single-end configuration
• Tight mill diameter tolerance of +0.000 to -0.002 inches

Compatibility

Designed as a standard Series 5B solid carbide ball end mill for use in conventional and CNC milling machines accepting a 3/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Verify that the machine spindle and tool holder are clean and free of debris before seating the shank. Power down and lock out the machine before inserting or removing the end mill. Follow the tool manufacturer and machine builder guidelines for runout inspection and tool-holder torque.
