Osg 404-6875 Square End Mill 11/16 in 4 Flute Solid Carbide

Product Description

The OSG 404-6875 is a solid carbide square end mill designed for precision milling of metals and engineered materials. This single-end tool features a 11/16 inch cutting diameter, a 1-3/8 inch length of cut, and a 4 inch overall length. The 4-flute configuration with a 30-degree helix angle promotes efficient chip evacuation and delivers a smooth surface finish. Machined from micrograin solid carbide, it offers the rigidity and wear resistance required for demanding milling operations in ferrous and non-ferrous applications. It is installed and operated by machinists and CNC programmers in production and job-shop environments.

The OSG 404-6875 is suited for slotting, profiling, and peripheral milling operations on machining centers and manual mills. Its centercutting geometry allows direct plunge entry into the workpiece. The 3/4 inch shank diameter fits standard ER and end mill holders used in vertical and horizontal milling setups. The spiral flute geometry and right-hand cut with right-hand flute configuration make it appropriate for conventional climb-milling strategies in steel, aluminum, and similar materials.

Key Features

• Solid micrograin carbide construction for extended tool life and rigidity
• 4-flute spiral design with 30-degree helix angle for efficient chip flow
• Centercutting capability allows direct plunge milling
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Uncoated finish suitable for use with cutting fluids in a wide range of materials
• Regular length series with 3/4 inch shank for broad holder compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for 3/4 inch end mill holders, collet chucks, and ER-style toolholders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool. Set tool length offset in the CNC controller before running the first pass. Apply appropriate cutting fluid or coolant as recommended for the workpiece material to extend tool life and maintain dimensional accuracy.
