Spiral Point Tap: MF4x0.5 Metric Fine, 3 Flutes, Plug Chamfer, 6H Class of Fit, Powdered Metal High-Speed Steel, AlCrN Coated MPN:6635107

The spiral point tap with MF4x0.5 metric size allows for tapping precision holes with minimal deformation when drilling into a range of materials such as mild steel, cast iron, stainless steel or aluminum up to about 3/16 diameter (dependent on the tool's geometry), using the plug chamfer helps maintain hole alignment during reaming and countersinking processes; being manufactured from powdered metal high-speed steel provides outstanding heat resistance for extended durability while the AlCrN coating minimizes friction, reduces wear as well as prevents oxidation allowing a smoother cutting action which contributes to its longevity. With it being part of 6H class fit (based on the ISO metric thread tolerance), you can achieve precise threads resulting in better functionality; these taps are suited for production facilities, machine shops or workshops that require high precision and high-speed drilling, as well as anyone looking to repair threads with little run-out while maintaining high accuracy.
