Spiral Flute Tap: 2-1/4-8 UN, 6 Flutes, Modified Bottoming, 2B Class of Fit, Vanadium High Speed Steel, Oxide Coated MPN:1302504001

The Spiral Flute Tap with a diameter of 2-1/4 inches and size of 8 UN is an essential tool for professionals working in various industries requiring precision threads on metallic materials such as stainless steel, aluminum, brass, or mild steel. Its spiral flute design provides excellent chip evacuation and improved coolant flow, ensuring smooth operation with reduced wear on the tap and the cutting edges. The 6 flutes offer a faster cutting speed while its Modified Bottoming thread form provides a more considerable thread root for enhanced holding power even in critical applications. Additionally, the 2B class of fit ensures a perfect match with the hole diameter allowing accurate and consistent threads. The vanadium high-speed steel construction delivers exceptional hardness and wear resistance while its oxide coating further enhances corrosion resistance, extending the tap's longevity significantly. This spiral flute tap is ideal for use in aerospace, automotive, or general machining applications where precision and durability are crucial.
