Osg 36041611 Square End Mill 0.75in 4-flute Solid Carbide

Product Description

The OSG 36041611 is a solid carbide square end mill designed for high-performance milling in metalworking and machining applications. It features a 0.75-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length with a 0.75-inch shank. The four spiral flutes run at a 30-degree helix angle, and the tool carries OSG WXL coating for improved wear resistance and heat dissipation. Built from micrograin carbide, this end mill is suited for demanding cuts in ferrous and non-ferrous materials. It is center-cutting, allowing plunge entry, and is part of OSG Series 3604.

This end mill fits standard milling machine spindles and CNC machining centers that accept 3/4-inch straight shanks. It is used in regular-length milling operations including slotting, profiling, and peripheral milling. Typical applications include job shops, tool and die work, aerospace component machining, and general precision metalworking. The right-hand cut and right-hand flute configuration suit the large majority of CNC and manual milling setups. At 1 pound, it is sized for direct installation without additional adapters in most ER and end mill holder systems.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• WXL coating reduces friction and extends tool life in ferrous materials
• 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Center-cutting geometry allows direct plunge milling
• Four spiral flutes for balanced material removal and surface finish
• Mill diameter tolerance of plus 0.0000 / minus 0.0008 inches for consistent fit

Compatibility

Designed as an OEM-style solid carbide square end mill in OSG Series 3604, compatible with any milling machine or CNC machining center that accepts a 3/4-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. The shank must be clean and free of chips or burrs before seating in the holder; use a calibrated torque wrench on the draw bolt or collet nut per the holder manufacturer specifications. Inspect the cutting edges before each use and replace the tool if chipping or excessive wear is observed. Follow applicable shop safety standards and machine guarding requirements during setup.
