Osg 36040911 Square End Mill 1/4 Inch 4 Flute Solid Carbide

Product Description

The OSG 36040911 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built on OSG Series 3604, it features a 1/4 inch cutting diameter with a 3/4 inch length of cut and a 2-1/2 inch overall length. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The WXL coating adds wear resistance for extended tool life. Centercutting capability allows plunge entry, giving machinists flexibility in tool paths without requiring a pre-drilled starting hole.

This end mill is suited for use in CNC machining centers and manual mills handling ferrous and non-ferrous workpiece materials. Its regular-length profile fits standard tool holders accepting a 1/4 inch shank. The micrograin carbide substrate supports consistent performance in finishing and light roughing passes. It is appropriate for job shops, tool rooms, and production environments where tight tolerances and repeatable results are required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• WXL finish coating for extended tool life and reduced friction
• Four right-hand spiral flutes with 30-degree helix for efficient chip removal
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute orientation for standard spindle operation
• Mill diameter tolerance of +0.0000 / -0.0008 inches for precise fitment

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 1/4 inch shank tool holders used in CNC and manual milling applications within the OSG Series 3604 product family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully and evenly in the collet or tool holder and torque the retention nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production run.
