Osg 412-2500 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The OSG 412-2500 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. Measuring 0.25 inches in diameter with a 0.5-inch length of cut and a 2.0-inch overall length, this stub-length tool delivers rigidity in tight setups. The 2-flute, 30-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention required for demanding cutting applications. It is center-cutting capable, allowing direct plunge entry into the workpiece. This end mill is intended for machinists and tool-and-die professionals running CNC or manual milling equipment.

The 412-2500 is suited for slotting, profiling, and plunging operations on a wide range of workpiece materials. Its stub length-to-diameter ratio makes it a practical choice where overhang must be minimized to reduce deflection and improve surface finish. The uncoated micrograin carbide construction is appropriate for applications where coolant is used and a coated tool is not required. Right-hand cut and right-hand flute configuration is standard for conventional spindle-up milling setups.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 2-flute spiral design with 30-degree helix angle for efficient chip removal
• Center-cutting geometry allows direct plunge milling
• Right-hand cut, right-hand flute for standard milling machine compatibility
• Stub overall length of 2.0 inches promotes rigidity and reduces deflection
• Uncoated finish suitable for use with coolant in a variety of materials

Compatibility

Designed as an OEM-style tooling option for standard 1/4 inch collets and tool holders used in CNC and manual milling applications within the OSG Series 412 product line.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the collet or tool holder. Confirm the shank is seated to the full gripping depth of the holder and that the collet or chuck is torqued according to the equipment manufacturer specification. Inspect the cutting edges for chips or damage before use.
