Osg 36040111 Square End Mill 1/16 in 4 Flute Solid Carbide

Product Description

The OSG 36040111 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built to Series 3604 specifications, it features a 1/16 inch cutting diameter, a 3/16 inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The micrograin carbide construction provides edge retention and dimensional stability in demanding cuts. The WXL finish enhances wear resistance and reduces heat buildup at the cutting edge. At 1-1/2 inches overall length with a 1/8 inch shank, this tool fits standard collet chucks and is suited for fine-detail work in ferrous and non-ferrous materials.

This end mill is used in CNC machining centers and manual milling machines for slotting, profiling, and contouring operations. The centercutting geometry allows plunge entry, making it effective for cavity work and pocket milling. The right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups. Its small diameter and regular-length profile make it well suited for finishing passes, tight-tolerance slots, and detail work where larger tooling cannot reach.

Key Features

• Solid micrograin carbide construction for edge retention and long tool life
• WXL coating finish reduces wear and thermal buildup during cuts
• 30-degree helix angle with 4 spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute for standard milling machine spindle compatibility
• Mill diameter tolerance of +0.0000 / -0.0008 inches for tight-fit slot work

Compatibility

Designed as an OEM-style replacement and standard-fit tool for CNC machining centers and manual mills using 1/8 inch collet or chuck systems. Belongs to OSG Series 3604.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the collet. Verify collet size matches the 1/8 inch shank diameter before tightening. Do not exceed the recommended depth of cut for the 3/16 inch length of cut to avoid tool deflection or breakage.
