Sgs 77474 Corner Radius End Mill 1 Inch 7 Flute Carbide

Product Description

The SGS 77474 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. The tool measures 1 inch in diameter with a 2.5-inch length of cut and carries a Ti-NAMITE-A coating that extends tool life in abrasive and hard-material environments. With 7 flutes and a variable helix geometry, it reduces chatter and promotes chip evacuation during aggressive cuts. The 0.12-inch corner radius protects the cutting edge and improves surface finish at part corners. This is a single-end, right-hand cutting tool with coolant-through capability, intended for use on CNC machining centers operated by skilled machinists and tool-and-die professionals.

The SGS 77474 is suited for milling steel, cast iron, stainless steel, high-temperature alloys, and hard materials. Its micrograin carbide substrate and Ti-NAMITE-A coating make it well-matched to tough, high-hardness workpieces where tool wear is a primary concern. The chipbreaker geometry further aids performance in deep-pocket and slotting operations where chip control is critical. This tool fits standard straight-shank toolholders with a 1-inch bore and is commonly deployed in production shops, aerospace component machining, and mold-and-die work.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in ferrous and high-temp alloys
• Ti-NAMITE-A coating provides enhanced hardness and heat resistance at the cutting edge
• Variable helix flute design reduces vibration and chatter during high-load cuts
• Coolant-through design delivers coolant directly to the cutting zone for heat management
• Chipbreaker geometry improves chip segmentation in deep-pocket and slotting operations
• 0.12-inch corner radius protects edge integrity and improves corner surface finish

Compatibility

Designed for use with standard straight-shank toolholders accepting a 1-inch shank diameter. Primary workpiece materials include steel, cast iron, stainless steel, and high-temperature alloys; secondary application covers hard materials.

Installation Notes

Installation requires a CNC machining center or manual mill with a straight-shank toolholder matched to the 1-inch shank diameter. Verify runout and toolholder clamping force before operation, as excessive runout will accelerate edge wear on carbide tooling. This tool is not center-cutting and should not be used for direct plunge entry. Coolant-through capability requires a machine spindle equipped with internal coolant delivery.
