Osg 445-1562 Square End Mill 5/32 in 3 Flute Solid Carbide

Product Description

The OSG 445-1562 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, this single-end tool features 3 spiral flutes with a 45-degree helix angle, delivering efficient chip evacuation and smooth cutting performance. The cutter measures 5/32 inch (0.1563 inches) in diameter with a 9/16 inch (0.5625 inches) length of cut. It is centercutting, allowing plunge entry directly into the workpiece. The bright, uncoated finish suits a wide range of ferrous and non-ferrous materials. Licensed machinists and CNC operators install and run this tool in production and job-shop environments.

The OSG 445-1562 is suited for slot milling, profiling, and peripheral milling operations in general machining. Its regular-length geometry and 3/16 inch (0.1875 inches) shank diameter make it compatible with standard collet chucks and end mill holders found on vertical machining centers, CNC knee mills, and manual milling machines. It is a strong choice for small-feature work requiring a sub-quarter-inch diameter cutter at a 45-degree helix, particularly in aluminum, brass, steel, and similar materials.

Key Features

• Micrograin solid carbide construction for rigidity and long tool life
• 3 spiral flutes with 45-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling into the workpiece
• Right-hand cut, right-hand flute configuration — standard CNC spindle direction
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Regular-length geometry fits standard collet and end mill holder tooling

Compatibility

Designed as a standard replacement or stock end mill in OSG Series 445. Fits any spindle setup accepting a 3/16 inch shank via collet chuck, ER collet, or end mill holder on vertical or horizontal milling equipment.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is tightened to the machine manufacturer's specification before running. Inspect the cutting edges for chips or damage before each use — carbide end mills are brittle and should not be dropped or impacted against hard surfaces.
