Osg 404-4724 Square End Mill 0.4724 in 4 Flute Carbide

Product Description

The OSG 404-4724 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers a 0.4724-inch (12.00 mm) cutting diameter with a 0.9843-inch (25.00 mm) length of cut. The four-flute, spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The centercutting geometry allows direct plunge entry into workpieces. Right-hand cut and right-hand flute orientation follow standard CNC and manual mill conventions. This tool is used by machinists and tool-and-die professionals in production and job-shop environments.

The 404-4724 suits general-purpose milling operations including slotting, profiling, and peripheral cutting in ferrous and non-ferrous materials. Its regular-length configuration and 12.00 mm shank diameter make it compatible with standard collets and end mill holders commonly found on vertical machining centers and knee mills. The uncoated micrograin carbide construction is well suited for applications where cutting fluid or coolant is used to manage heat at the tool-workpiece interface.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine spindle fully stopped and locked out per applicable safety procedures. Ensure the collet or end mill holder is clean and free of debris before seating the shank. Verify runout with a dial indicator before commencing cuts. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
