Osg 5209200 Square End Mill 7/32 in 2 Flute Cobalt

Product Description

The OSG 5209200 is a square end mill designed for precision milling operations in metal cutting applications. Built from M42 cobalt high-speed steel, this tool delivers durability and heat resistance in demanding machining environments. It features a 7/32 inch (0.2188 inch) cutting diameter with a 1/2 inch length of cut, a 3/8 inch shank diameter, and a 2-5/16 inch overall length. The two-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation. Center-cutting capability allows for direct plunging into workpieces. The bright, uncoated finish is the as-ground standard for cobalt tooling.

This end mill is suited for general-purpose milling tasks including slotting, profiling, and facing on ferrous and non-ferrous materials. Its regular-length configuration and compact 7/32 inch diameter make it appropriate for detail work, tight pockets, and features requiring smaller-diameter tooling. It is compatible with standard CNC machining centers and manual mills equipped with an appropriate collet or chuck accepting a 3/8 inch shank. Machinists and tool and die professionals working in job shops, maintenance, and production environments are the primary users.

Key Features

• M42 cobalt steel construction for heat and wear resistance in ferrous materials
• 7/32 inch cutting diameter with 1/2 inch length of cut for controlled depth passes
• Two-flute, right-hand spiral design with 30-degree helix for effective chip removal
• Center-cutting geometry allows direct plunging without pre-drilling
• Bright/uncoated finish suited for cobalt-grade tooling without additional coating
• 3/8 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed for use in standard CNC and manual milling machines accepting a 3/8 inch straight shank. Consult machine specifications to confirm collet or chuck compatibility before use.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and powered down before inserting or removing the end mill. Secure the shank fully within the collet or end mill holder to the manufacturer-recommended engagement depth to prevent pullout during cutting. Verify runout with a dial indicator after installation before initiating a cut.
