Sgs 70487 Square End Mill 3/4 in 4 Flute Solid Carbide Altin

Product Description

The SGS 70487 is a solid carbide square end mill designed for high-performance milling in demanding production environments. Built on the Series 7 platform, it features a 3/4 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length with a straight cylindrical shank. The AlTiN coating improves heat resistance and extends tool life when cutting harder alloy steels, stainless, titanium, and high-temp alloys. Four spiral flutes with a 38-degree helix angle and variable index geometry reduce chatter and improve chip evacuation. Micrograin carbide substrate provides the hardness and edge retention needed for aggressive material removal at elevated feed rates.

This end mill is suited for CNC machining centers handling steel, cast iron, non-ferrous metals, and exotic alloys, corresponding to ISO material groups H, K, M, P, and S. The extra-long configuration and 3 inch length of cut make it appropriate for deep-pocket milling, cavity work, and side milling where reach beyond standard lengths is required. The centercutting geometry allows for direct plunging. Right-hand cut and right-hand flute orientation is standard. A licensed machinist or CNC programmer typically selects and sets up this tooling in a production shop environment.

Key Features

• AlTiN finish for elevated heat resistance and extended tool life in hard and abrasive materials
• 38-degree helix spiral flute design promotes smooth cutting action and efficient chip removal
• Variable index flute spacing reduces harmonic vibration and chatter during heavy cuts
• Centercutting capability allows direct plunge entry without pre-drilled pilot holes
• Micrograin carbide substrate delivers consistent edge retention across long production runs
• Extra-long length classification with 3 inch LOC suited for deep-pocket and cavity milling

Compatibility

Designed for use in CNC machining centers and milling machines accepting 3/4 inch straight cylindrical shank toolholders. Compatible with ISO material groups H, K, M, P, and S, covering hardened steels, cast iron, stainless steels, carbon steels, and high-temperature alloys.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine spindle fully stopped and control in a safe state. Use a torque-rated toolholder appropriate for 3/4 inch straight shank tooling and verify runout after seating. Confirm cutting parameters including spindle speed, feed rate, and depth of cut against published speeds and feeds for the specific workpiece material before initiating the cut. Do not exceed the recommended length of cut for side milling passes without verifying deflection limits.
