Spiral Flute Tap: M4 x 0.70, Metric Coarse, 3 Flute, Bottoming, 6H Class of Fit, Vanadium High Speed Steel, Bright/Uncoated MPN:4130557

The Spiral Flute Tap M4 x 0.70 is ideal for precision tapping applications in Aerospace, Automotive, Medical and Engineering industries where a top quality cut is critical for achieving the best finishes on high-strength materials such as steel, castings, stainless steel and titanium alloys. This metric coarse 3 flute bottoming tap features bright vanadium high-speed steel, making it excellent in both high production and low volume settings at affordable prices. The B6H Class of fit provides accurate hole tolerance with easy plugging in tapered, blind, spotface or through holes; while its spiral flutes prevent chip welding by continuously removing chips resulting in cleaner threads. Suited for high feed rates with low vibration and noise levels to deliver superior performance, this bright uncoated tap eliminates the need for PVD coatings or plating for improved wear resistance against chip buildup on cutting edges and lands ensuring long tool life with smooth and accurate holes every time.
