Spiral Point Tap: 1-8 UNC, 4 Flutes, Plug Chamfer, 2B Class of Fit, High-Speed Steel-E-PM, TiN Coated MPN:9039920254000

Grainger's precision Spiral Point Tap offers superior performance in machining and tooling applications where the highest thread quality is required for metallic materials. With a UNC #1-8 size, this high-speed steel tool excels at cutting through hard metal such as stainless steel or aircraft-grade aluminum without compromising threads' integrity. Its 4 flutes provide excellent chip removal rates and decreased thrust forces allowing users to achieve extended service life while the plug chamfer prevents reaming and minimizes thread damage. This Spiral Point Tap features TiN coating which provides improved lubricity, enhanced durability against heat buildup on difficult-to-cut metals, and lengthens its lifespan compared to uncoated equivalents. Its exceptional cutting ability makes it a preferred choice among automotive or aerospace manufacturers; precision machining shops, and engineering firms that seek accurate thread creation without compromises in performance or quality.
