Osg 36040311 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The OSG 36040311 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineered plastics. It features a 3/32 inch (0.0938 inch) cutting diameter, a 4-flute spiral geometry with a 30-degree helix angle, and OSG WXL finish coating for extended tool life in demanding cutting applications. The 1/8 inch shank diameter fits standard collet toolholders, and the centercutting design allows plunge entry. Machinists and tooling specialists use this end mill in CNC machining centers and manual knee mills where fine-feature work, slot milling, and contour cutting are required at small diameters.

This end mill is suited for finish milling, slotting, and profiling in small-bore and fine-detail applications across job shops, aerospace component shops, and precision manufacturing environments. The regular-length configuration keeps deflection low at this diameter. The right-hand cut and right-hand flute geometry is the standard configuration for conventional and climb milling on most CNC platforms. It is sold individually and is intended for professional machining use.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance at small diameters
• WXL finish coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 30-degree helix spiral flute geometry promotes chip evacuation and smooth cutting action
• Centercutting design enables direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute configuration compatible with standard CNC spindle rotation
• Series 3604 regular-length build minimizes deflection at 3/32 inch cutting diameter

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills accepting a 1/8 inch shank collet or end mill holder. Part of the OSG Series 3604 product family.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the 1/8 inch shank fully into a properly sized collet or toolholder and verify runout before cutting. Ensure the machine spindle is fully stopped and the control is in a safe state before changing or measuring tooling. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and depth of cut.
