Sgs 77179 Corner Radius End Mill 1/2 in 7 Flute Carbide

Product Description

The SGS 77179 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding materials. It carries a 1/2-inch mill diameter, a 0.03-inch corner radius, and 7 helical flutes arranged in a close-pitch, variable-index pattern. The TiN coating reduces friction and extends tool life during extended cuts. With a 1-1/4-inch length of cut and 3-1/4-inch overall length, this single-end tool is engineered for controlled metal removal in tight tolerances. The micrograin carbide substrate supports rigidity and edge retention in abrasive workpiece materials. It is intended for use with standard end mill holders.

This end mill is suited for finishing passes on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The right-hand flute direction and right-hand cutting direction make it compatible with conventional CNC milling setups. The chipbreaker geometry and high helix style support chip evacuation during deep-reach finishing applications in vertical and horizontal machining centers. It is appropriate for both production shops and toolroom environments where surface finish and dimensional accuracy are priorities.

Key Features

• 0.03-inch corner radius reduces stress concentrations and improves surface finish at part edges
• 7 helical flutes with close pitch and variable index for vibration damping and smooth cutting action
• Solid micrograin carbide construction for edge retention in hard and abrasive materials
• TiN coating reduces friction and extends tool life in steel, stainless steel, and superalloy applications
• Chipbreaker geometry aids chip evacuation during finishing passes
• Right-hand cut, right-hand helix, single-end configuration for standard CNC spindle compatibility

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Secondary application covers hard materials. Shank diameter tolerance is h6 for consistent holder fitment.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the straight cylindrical shank in a properly sized end mill holder and verify runout before starting a cut. Do not use this tool for centercutting operations, as it is not center-cutting capable. Follow machine tool manufacturer guidelines for spindle speeds and feed rates appropriate to the workpiece material and depth of cut.
