Sgs 30778 Square End Mill 1/8 Inch 3 Flute Solid Carbide

Product Description

The SGS 30778 is a solid carbide square end mill designed for precision milling in a wide range of metalworking applications. It features a 1/8 inch cutting diameter, a 1/2 inch length of cut, and a 1-1/2 inch overall length with a straight cylindrical 1/8 inch shank. The three-flute geometry combined with a 30-degree spiral helix and TiCN coating delivers efficient chip evacuation and extended tool life in demanding cutting conditions. Centercutting capability allows both plunge and profile operations. This tool is built from micrograin solid carbide for rigidity and wear resistance at small diameters.

The SGS 30778 is suited for slot milling, profiling, and contouring operations on a broad range of workpiece materials including cast iron, non-ferrous metals, stainless steels, carbon steels, high-temperature alloys, and hardened materials. Its compact 1/8 inch diameter makes it a common choice for detailed work in die and mold, aerospace component machining, and precision part manufacturing. Right-hand cut and right-hand flute orientation follow standard CNC machining center conventions.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• TiCN coating for improved surface hardness and lubricity across varied workpiece materials
• Three-flute spiral design at 30-degree helix angle for balanced chip load and smooth finish
• Centercutting geometry enables direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for use in standard CNC and manual milling setups
• Regular length Series 5 classification for consistent reach and rigidity

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 1/8 inch collet or tool holder systems on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Use a torque wrench and appropriate collet nut tool when tightening to the tool holder specification. Verify runout with a dial indicator before beginning the cut, as small-diameter carbide end mills are sensitive to excessive runout and can fracture.
