Osg 6737605 Square End Mill 1/8 in 2 Flute Tin Hss

Product Description

The OSG 6737605 is a square end mill designed for precision milling operations in metalworking and machining applications. Built from M35 powdered metal high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and improved wear resistance compared to standard HSS tooling. The 1/8 inch cutting diameter and 3/8 inch length of cut make it well suited for slotting, profiling, and peripheral milling in tight geometries. The 30-degree helix angle promotes smooth chip evacuation, while the right-hand cut and right-hand spiral flute configuration are standard for most CNC and manual milling setups. This is a single-end, centercutting tool, so it can plunge directly into workpiece material.

This end mill is used in machine shops, tool rooms, and production environments where small-diameter precision cutting is required. It fits applications in ferrous and non-ferrous metals where an M35 cobalt-content steel provides the hardness and heat resistance needed at elevated feeds and speeds. The regular length designation and compact 1-7/8 inch overall length make it a practical choice for close-tolerance work in vertical milling machines and CNC machining centers.

Key Features

• M35 powdered metal high speed steel construction for elevated hardness and heat resistance
• Titanium nitride (TiN) coating extends tool life and reduces friction at the cutting edge
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece material
• 2-flute configuration provides adequate chip clearance in slotting and profiling cuts
• OSG Series 673 regular-length design for consistent dimensional repeatability

Compatibility

Designed for use in standard 3/16 inch collets or end mill holders on CNC machining centers and manual vertical mills. Fits applications within the 0.300 to 0.500 inch length-of-cut range for this tool class.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated collet or end mill holder rated for the 3/16 inch shank diameter to maintain runout tolerances. Verify tool projection and engagement length before initiating a cut to prevent deflection or premature tool failure.
