Spiral flute taps are precision-engineered cutting tools designed for creating screw threads in metal surfaces. This model is a #4-40 UNC type and offers two flutes, a modified bottoming style with a class 2B fit, and features a vanadium high-speed steel construction with an oxide coating. The two-flute design helps reduce chips, while the spiral design improves chip evacuation and provides strong tapping strength. The modified bottoming style prevents overstress on threads when starting into holes or reaming operations. This tap is ideal for professionals working in machining, automotive repair, aerospace engineering, and hobbyists who require precision and durability when creating screw threads in metal surfaces. Its coated construction increases its lifespan and ensures superior performance.
