The SGS 30123 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers consistent edge integrity and wear resistance across a wide range of workpiece materials. The 30123 features a 3/16 inch cutting diameter, a 5/8 inch length of cut, and a 30-degree right-hand helix. With four flutes and a variable index design, it promotes smooth chip evacuation and reduces chatter during profiling, slotting, and peripheral milling operations. This single-end tool ships uncoated and ready for use in standard CNC or manual milling setups.
This end mill is suited for use in machine shops, manufacturing facilities, and production environments where close-tolerance milling is required. It is appropriate for use on CNC machining centers and manual knee mills. The primary workpiece material codes listed by the manufacturer cover cast iron, non-ferrous metals, stainless steel, aluminum and its alloys, steel, and high-temperature alloys. The regular length configuration and straight-cylindrical shank make it a straightforward fit for standard collet chucks and end mill holders commonly found in production tooling setups.
Designed for use on workpiece materials corresponding to ISO material codes H, K, M, N, P, and S, covering hardened materials, cast iron, stainless steel, non-ferrous metals, steel, and high-temperature alloys. Fits standard 3/16 inch collet chucks and end mill holders.
Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out. Ensure the collet or tool holder is clean and free of debris before seating the shank. Verify runout after mounting and confirm tool projection is appropriate for the intended depth of cut. Follow machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds.
