Osg 412-4375 Square End Mill 7/16 Inch 2 Flute Carbide

Product Description

The OSG 412-4375 is a solid carbide square end mill designed for precision milling in metal, composite, and hard material applications. It features a 7/16 inch cutting diameter with a 5/8 inch length of cut and a stub-length overall length of 2-1/2 inches. The two-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, it delivers rigidity and wear resistance suited to high-tolerance machining work. This is a centercutting end mill, meaning it can plunge directly into a workpiece. It runs right-hand cut with right-hand flute spiral and is supplied uncoated.

The 412-4375 is suited for slot milling, peripheral milling, and plunge operations in ferrous and non-ferrous materials. The stub-length profile provides added rigidity in setups where minimal overhang is critical, making it a practical choice for die and mold work, fixture machining, and general-purpose CNC milling. The 7/16 inch shank diameter matches the cutting diameter, simplifying toolholder selection in standard collet chucks and end mill holders.

Key Features

• 7/16 inch cutting diameter with matching 7/16 inch shank diameter for straightforward toolholder compatibility
• Micrograin solid carbide construction for extended tool life in demanding cuts
• 30-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Stub overall length of 2-1/2 inches maximizes rigidity and minimizes deflection
• Right-hand cut and right-hand flute, uncoated — ready for use or customer-applied coating

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 7/16 inch collet chucks and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
