Sgs 30125 Square End Mill 13/64 in 4 Flute Solid Carbide

Product Description

The SGS 30125 is a solid carbide square end mill designed for precision milling in a wide range of materials. With a 13/64 inch (0.2031 inch) cutting diameter and 4 flutes, it delivers efficient chip evacuation and consistent surface finishes in ferrous and non-ferrous metals, high-temperature alloys, and composite materials. The 30-degree right-hand spiral helix balances cutting force and chip flow. Micrograin carbide construction provides the edge retention and rigidity needed for demanding milling operations. This tool is suitable for CNC machining centers and manual mills where tight tolerances and repeatable performance are required.

The SGS 30125 is intended for use in professional machining environments including job shops, production machining, and tool rooms. Its 5/8 inch length of cut and 2-1/2 inch overall length make it well suited for shallow-to-medium depth slotting, profiling, and contouring operations. The primary workpiece material codes H, K, M, N, P, and S indicate compatibility with cast iron, non-ferrous metals, stainless steel, non-metals, steel, and high-temperature alloys. The straight cylindrical 1/4 inch shank fits standard collets and end mill holders commonly found in light-duty to mid-range machining setups.

Key Features

• Micrograin solid carbide construction for extended tool life and edge integrity
• 4-flute spiral design with 30-degree right-hand helix for balanced cutting forces
• Variable index geometry reduces chatter during milling passes
• Centercutting capability allows plunge entry into the workpiece
• Bright/uncoated finish suitable for use with or without cutting fluid
• Mill diameter tolerance of +0.000 / -0.002 inch for precise fitment

Compatibility

Designed for use in standard 1/4 inch collets and end mill holders on CNC and manual milling machines. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, non-metals, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Verify that the collet or end mill holder is clean and free of debris before seating the shank. Confirm proper runout with a dial indicator before beginning cuts, particularly when tolerances are tight.
