Spiral Flute Tap: M16 M, 3 Flutes, Semi-Bottoming, 6H Class of Fit, High Speed Steel, Uncoated MPN:8251228

Seco's spiral flute tap is designed for through-hardened materials such as cast iron, mild steel, aluminum, brass and copper. This tool is made of high speed steel (HSS) to provide exceptional durability and can easily drill holes without breaking or bending due to its unique design. The 3 flutes help eject chips from the hole efficiently while reducing clogging and heat generation. With a 6H class of fit, this tap provides greater accuracy in starting and ending tapped holes accurately while maintaining consistent thread depths. The spiral flute design also ensures cooler drilling and reduces cutting pressure resulting in faster and smoother performance for professional users. The uncoated high speed steel offers excellent durability even without coatings, making this tap the perfect choice for applications that require frequent change of tapping operations.
