OSG 447-6250 Left-Helix Carbide Square End Mill

The OSG Square End Mill 447-6250 is a left-helix carbide end mill designed for high-precision slotting, profiling, and contouring in ferrous and non-ferrous materials. It is commonly used in CNC machining centers for mold and die work, aerospace components, and general industrial manufacturing where square shoulders and tight tolerances are required.

The OSG Square End Mill 447-6250 is a carbide, 4-flute, left-helix end mill with a 5/8" mill diameter, 1-1/4" length of cut (LOC), and 3-1/2" overall length (OAL). It is designed for square shoulder milling and is suitable for use on a variety of materials including steel, stainless steel, and titanium alloys.

You can source the OSG Square End Mill 447-6250 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this OSG end mill to procurement teams and plant engineers internationally.

To select the correct OSG square end mill, match the mill diameter and length of cut to your workpiece geometry and material. For general machining of steel, a 4-flute design like the 447-6250 provides good chip evacuation and surface finish. Consider the helix angle—left-helix tools are ideal for climb milling and reducing chatter in thin-walled parts.
