Osg 424-0938 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The OSG 424-0938 is a double-end square end mill designed for precision milling in metal and hard material applications. Built from micrograin solid carbide, this stub-length tool measures 3/32 inches (0.0938 inches) in diameter with a 3/16 inches (0.1875 inches) length of cut. The four-flute configuration paired with a 30-degree right-hand spiral helix delivers efficient chip evacuation and smooth surface finish at higher feed rates. A bright, uncoated finish keeps the tool ready for use across a range of general-purpose milling operations without any additional coating treatment. Licensed machinists and CNC operators are the primary users of this tool.

The 424-0938 is suited for light-duty precision slot milling, profiling, and contouring where a small-diameter, stub-length end mill is required. The double-end design extends tool life by providing two usable cutting ends on a single shank. The 1/8 inches shank diameter accommodates standard collet and end mill holder setups commonly found on CNC machining centers and manual knee mills. This tool is particularly well suited for fine-detail work in mold making, die work, and small component machining.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• Double-end design provides two cutting ends, extending overall tool life
• Four flutes with 30-degree right-hand spiral helix for efficient chip flow and surface finish
• Stub length of cut reduces deflection in tight-tolerance applications
• Bright, uncoated finish suitable for general-purpose milling without specialized coating requirements
• Right-hand cutting direction compatible with standard CNC and manual milling setups

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers and manual mills accepting a 1/8 inches diameter shank with standard collet or end mill holder tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the machine powered down and spindle locked. Ensure the collet or tool holder is clean and free of debris before seating the shank to the correct depth. Verify runout with a dial indicator before beginning cuts. Do not exceed the rated depth of cut or feed rate for the material being machined.
