Sgs 70486 Square End Mill 3/4 Inch 4 Flute Solid Carbide

Product Description

The SGS 70486 is a solid carbide square end mill engineered for high-performance milling in demanding metal-cutting applications. Built on the Series 63 platform, it features a 0.750 inch mill diameter, a 2.25 inch length of cut, and a 5.0 inch overall length on a 0.750 inch straight-cylindrical shank. The micrograin carbide substrate delivers hardness and edge retention that high-speed steel cannot match. An AlTiN coating provides oxidation resistance and thermal stability at elevated cutting temperatures. The variable index geometry reduces chatter and harmonic vibration, making this an end mill suited to aggressive material removal in ferrous and exotic alloy programs. A licensed machinist or CNC programmer will specify this tool for jobs where rigidity and surface finish both matter.

The SGS 70486 is designed for milling in ISO workpiece material groups H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon steels, and high-temperature alloys. The long flute length of 2.25 inches accommodates deep shoulder milling, slotting, and profiling operations where standard-length end mills fall short. Its centercutting geometry allows plunge entry when the tool path requires it, giving programmers flexibility in approach strategy without requiring a separate roughing step.

Key Features

• AlTiN finish for elevated heat resistance and extended tool life in hard and exotic alloys
• Variable index flute spacing reduces harmonic chatter during full-slot and deep-shoulder cuts
• Centercutting design permits direct plunge entry without a pre-drilled pilot hole
• Micrograin carbide substrate maintains sharp cutting edges under high feed and speed conditions
• Right-hand cut, right-hand spiral flute configuration compatible with standard CNC spindle rotation
• 38-degree helix angle promotes efficient chip evacuation in long-flute cutting scenarios

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual knee mills accepting a 0.750 inch straight-cylindrical shank. Rated for ISO material groups H, K, M, P, and S as specified in the product data.

Installation Notes

Install in a properly sized collet or end mill holder rated for the 0.750 inch shank diameter and torque to the toolholder manufacturer's specification. Verify runout at the cutting tip before initiating a program, as excessive runout accelerates edge wear and reduces dimensional accuracy. Always power down and lock out the spindle before changing tooling. Follow shop-specific speeds and feeds documentation for the workpiece material group and depth of cut being programmed.
