Spiral Flute Tap: M4x0.70 Metric Coarse, 3 Flutes, Modified Bottoming, 6H Class of Fit, Vanadium High Speed Steel, Oxide Coated MPN:2290601

The spiral flute tap M4x0.70 metric coarse, 3 flutes, Modified bottoming, 6H class of fit is designed for tapping through hole in softer material like aluminum and other non-ferrous materials. It provides efficient thread forming while leaving burr-free holes in the process. Vanadium high-speed steel construction makes it hardened for heat and wear resistance providing long lasting performance under extreme conditions. Oxide coated finish increases lubricity during cutting operations and makes the tool corrosion resistant. Its applications include use by engineers, mechanics, technicians, and hobbyists in machining, maintenance and repair industries requiring M4 metric tap size holes or similar thread patterns on metal workpieces.
