Sgs 30131 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The SGS 30131 is a solid carbide square end mill designed for precision milling in a wide range of materials. With a 1/4 inch cutting diameter, 3/4 inch length of cut (LOC), and 4 flutes, it delivers clean, accurate cuts in ferrous and non-ferrous metals, composites, and high-temperature alloys. The 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. A micrograin carbide grade provides the hardness and wear resistance needed for demanding cutting applications. This tool is a single-end, right-hand cutting end mill with a bright uncoated finish, suited for use in manual mills and CNC machining centers.

This end mill is intended for use in metal fabrication shops, tool rooms, and production machining environments. It handles a broad primary workpiece material range, including cast iron, non-ferrous metals, stainless steel, steel, superalloys, and other machinable materials. The straight-cylindrical shank fits standard 1/4 inch collet chucks and end mill holders. With a regular-length classification and 2.5 inch overall length, it is well suited for general-purpose profiling, slotting, and peripheral milling operations where rigidity and tool life are priorities.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 4-flute, variable index geometry for improved chatter resistance and surface finish
• 30-degree right-hand spiral helix for efficient chip evacuation
• Centercutting capable, allowing plunge entry into workpiece material
• Bright uncoated finish suitable for a wide range of base materials
• Right-hand cutting direction, compatible with standard spindle rotation

Compatibility

Designed as a direct-fit replacement for standard 1/4 inch diameter, 4-flute solid carbide square end mills used in CNC and manual milling applications across ferrous metals, non-ferrous metals, stainless steel, and high-temperature alloy workpieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the collet or end mill holder to the recommended engagement depth before tightening to prevent pullout under cutting loads. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Verify runout after installation using a dial indicator before beginning the cut.
