Sgs 00556 Square End Mill 3/64 in 4 Flute Solid Carbide

Product Description

The SGS 00556 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 3/64 inch (0.0469 inch) cutting diameter and a 9/64 inch (0.1406 inch) length of cut, this tool handles tight-tolerance work where rigidity and edge sharpness are critical. The four-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining a clean finished surface. The micrograin carbide construction provides the hardness and wear resistance needed for cutting ferrous and non-ferrous materials. It is installed and operated by machinists and CNC tooling professionals.

The SGS 00556 is suited for slot milling, profiling, and contouring operations on CNC machining centers and manual mills. Its small diameter makes it appropriate for fine-feature work, engraving details, and narrow slot cutting in molds, dies, and precision components. The straight cylindrical shank fits standard 1/8 inch collet chucks. This is a single-end tool in the SGS Series 1810 line, offered in a bright uncoated finish for general-purpose use across a range of work materials.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• Four-flute right-hand spiral design for efficient chip evacuation and surface finish
• Center-cutting capable, allowing plunge cuts directly into the workpiece
• Straight cylindrical shank, 1/8 inch diameter, compatible with standard collet systems
• Bright uncoated finish suitable for general-purpose milling of various materials
• Regular length geometry balances rigidity and reach for small-diameter work

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8 inch collet or tool holder systems; part of the SGS Series 1810 square end mill line.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth and torque the collet nut per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout significantly reduces tool life and surface quality on small-diameter end mills.
