Cleveland HSS End Mill 39743

The Cleveland C39743 is a square end mill made from high-speed steel for general-purpose milling. It features a 0.75 inch cutting diameter and a 3 inch length of cut. The tool has an uncoated finish and a Weldon flat shank for secure holder retention. Overall length measures 5 1/4 inches with a 3/4 inch shank diameter.

Machinists needing long reach in steel

This tool suits machinists who need extended reach for deep pockets or cavities in ferrous materials. The high-speed steel substrate handles interrupted cuts and less rigid setups better than carbide alternatives. Buyers who need higher material removal rates in hardened alloys or who require coated tooling for heat resistance should look at different tooling.

3 inch length of cut

The 3 inch length of cut is the critical dimension that determines whether this end mill reaches the required depth in a single pass. It defines the maximum axial engagement possible without multiple setups or a longer tool. Verify that your workpiece depth and fixture clearance match this cutting length before purchasing.
