Sgs 70559 Square End Mill 0.5512in 4 Flute Altin Carbide

Product Description

The SGS 70559 is a solid carbide square end mill designed for high-performance milling in demanding industrial machining applications. Built on the Series 7MS platform, it features a 0.5512-inch cutting diameter, a 2.9528-inch length of cut, and a 4-flute spiral geometry with a variable index configuration. The AlTiN coating provides heat and oxidation resistance, making this tool well-suited for dry or high-speed cutting conditions. The micrograin carbide substrate delivers edge integrity under aggressive feed rates. This end mill is intended for use by machinists and CNC tooling professionals in production and job-shop environments.

This end mill is rated for use on a broad range of workpiece materials, including hardened steels, cast iron, stainless steel, titanium alloys, and high-temperature superalloys, as indicated by the primary workpiece material codes H, K, M, P, and S. Its regular-length classification and straight-cylindrical shank make it compatible with standard ER collet chucks and end mill holders. It is centercutting, allowing plunge entry. Typical applications include slotting, profiling, and peripheral milling on CNC machining centers and mills.

Key Features

• 0.5512-inch cutting diameter with matching 0.5512-inch straight-cylindrical shank
• 2.9528-inch length of cut suited for deep-pocket and extended-reach slotting
• 4-flute spiral geometry with variable index for reduced chatter and improved surface finish
• AlTiN coating for elevated heat resistance and extended tool life in dry cutting
• Micrograin solid carbide substrate for consistent edge sharpness and wear resistance
• Centercutting capability allows direct plunge milling without a pre-drilled entry point
• Right-hand cut, right-hand flute orientation for standard CNC spindle compatibility

Compatibility

Rated for workpiece material codes H, K, M, P, and S, covering hardened steels, cast iron, stainless steels, titanium, and superalloys. Designed as an OEM-style replacement and production cutting tool in the SGS Series 7MS end mill line.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before inserting or removing the end mill from its holder. Verify shank diameter tolerance and holder bore compatibility before seating the tool. Torque collet nuts and set screws according to the toolholder manufacturer specifications, not values specific to this end mill.
