Spiral Flute Tap: M4 x 0.70, Metric Coarse, 3 Flute, Modified Bottoming, 6H Class of Fit, Cobalt, TiN Finish MPN:4445809

The SIGMAT593991 M4 x 0.70 metric coarse spiral flute tap is ideal for through holes in softer materials such as aluminum or brass with a minimum of breakage, splintering or burr formation. Its 3-flutes design ensures efficient chip removal and reduced friction while thread cutting which minimizes the risk of damaging the thread form. The modified bottoming feature prevents stripping out at the bottom of the hole while the cobalt composition ensures strength and durability. Its TiN coating improves wear resistance and reduces galling for longer tap life, making it perfect for manufacturing applications in the aerospace, automotive or medical industries where precision thread cutting is essential.
