Osg 462-125011 Square End Mill 0.125in 2 Flute Solid Carbide

Product Description

The OSG 462-125011 is a solid carbide square end mill engineered for precision milling in demanding shop environments. Measuring 0.125 inches in diameter with a 0.75-inch length of cut and a 2.25-inch overall length, this tool is built for tight-tolerance work in steel, stainless, cast iron, and hardened materials. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. With a 30-degree helix angle and spiral flute geometry, it delivers efficient chip evacuation and reduced cutting forces. Licensed machinists and CNC operators specify this tool for finishing and semi-finishing passes where dimensional accuracy is critical.

This end mill is suited for vertical machining centers, CNC mills, and manual knee mills running right-hand spindle rotation. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole, making it adaptable to slotting, profiling, and pocket milling operations. The long-length configuration supports applications requiring extended reach into deep pockets or stepped features. Micrograin carbide substrate provides the edge retention needed in abrasive or hard workpiece materials.

Key Features

• 0.125-inch diameter with matching 0.125-inch shank for direct collet or end mill holder mounting
• TiAlN finish for high-temperature wear resistance and extended tool life
• 30-degree helix angle with spiral flutes for smooth cutting action and efficient chip removal
• Centercutting design allows direct plunge milling without a pilot hole
• Micrograin solid carbide substrate delivers consistent edge sharpness in hard materials
• Right-hand cut and right-hand flute geometry for standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for applications requiring a 0.125-inch diameter square end mill in Series 462 long-length configuration with a 0.125-inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a properly sized collet or end mill holder and torque to the machine tool manufacturer's specification. Verify spindle direction is set to right-hand rotation before engaging the cut. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
