Spiral Flute Tap: #4-40, UNC, 2 Flute, Semi-Bottoming, 2B & 3B Class of Fit, Powdered Metal, Bright/Uncoated MPN:TT97207

The #4-40 UNC spiral flute tap with 2B & 3B class of fit, powdered metal construction is engineered to provide top-performance on hard metals such as steel & stainless steel through its durability, precision threading, and reduced breakage risk. The two flutes offer efficient chip removal whilst ensuring minimal vibrations and tool deflection during the cutting process; while the 2B and 3B class of fit accommodate a broader range of tolerances minimizing slippage or wobble on workpieces - leading to accurate results in critical applications. Powdered metal offers greater wear resistance than high speed steel while staying cost-competitive, increasing value for money against alternatives, and its bright uncoated surface finish eliminates the need for additional coatings preserving edge sharpness cutting through stubborn alloys with ease. With overall length measuring 2 inches, it's ideal for applications in automotive, aerospace or electrical manufacturing segments where quality threads are demanded without compromise on turnaround times due to its precision, reliability & efficiency; even at fractional sizes suitable for intricate setups requiring close-fitting parts.
