Spiral Flute Tap: M4 x 0.70, Metric, 3 Flute, Modified Bottoming, 6H Class of Fit, Powdered Metal, Bright/Uncoated MPN:03000154

Our spiral flute tap for M4 metric threads offers high performance machining capabilities with its three-flute design enabling faster and efficient chip removal while creating superior thread geometry due to a specialized profile designed for better chip evacuation from the hole. The modification bottoming style makes it suitable for breaking through previously machined holes without deformation or damaging work pieces, making it ideal for manufacturing processes demanding precision threads that meet dimensional tolerances without wear during repeated use. Its 6H fit class designates an excellent combination of strength and hardness while retaining tapping accuracy with a sharp cutting edge on all flutes resulting in outstanding durability compared to other tool materials.
