Osg 5730200 Square End Mill 5/32 in 2 Flute Vanadium Hss

Product Description

The OSG 5730200 is a square end mill ground from 3 percent vanadium high speed steel, designed for milling, slotting, profiling, and side milling operations in metalworking and general machining environments. It carries a 5/32 inch cutting diameter with a 7/16 inch length of cut and a standard 3/8 inch shank diameter. The 2-flute geometry and 30-degree right-hand spiral flute design promote efficient chip evacuation and reduce cutting forces, making this configuration well-suited for work in softer metals, plastics, and composites where chip clearance matters. Licensed machinists and tool-and-die professionals are the primary installers of this tooling.

This end mill fits standard milling machine spindles, CNC machining centers, and manual knee mills that accept a 3/8 inch shank. It is built to the OSG Series 573 specification for regular-length square end mills. Its centercutting geometry allows plunge milling operations in addition to peripheral and side cuts. Uncoated vanadium HSS construction is appropriate for general-purpose machining where coolant is applied and workpiece materials are not highly abrasive.

Key Features

• Centercutting design allows both plunge and peripheral milling operations
• 30-degree right-hand spiral flute promotes chip evacuation and smooth cutting action
• 3 percent vanadium high speed steel composition provides improved wear resistance over standard M2 HSS
• 2-flute configuration maximizes chip clearance when cutting softer or gummy materials
• Uncoated finish suits general-purpose use with standard cutting fluids
• Right-hand cut and right-hand flute orientation for conventional spindle direction

Compatibility

Designed for use in milling machine spindles and CNC machining center tool holders that accept a 3/8 inch straight shank. Part of the OSG Series 573 regular-length square end mill line.

Installation Notes

Installation and setup should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling from any collet or end mill holder. Verify shank runout and holder cleanliness before tightening to reduce tool deflection and premature wear. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material being machined.
