Practical usage tips

• Use an appropriate cutting fluid or tapping oil to maintain sharpness and extend tool life.
• Begin with a steady, centered drill hole, maintaining steady pressure as you guide the tap to prevent thread distortion.
• Whether you’re tapping by hand or with a machine, apply light, continuous feeding to avoid overloading the flutes.
• Keep the tap straight and back off slightly after every full turn to break chips and reduce friction.
• Clean the tap after use and store in a dry environment to prevent corrosion on the uncoated surface.

With the Wiseman M60x5.5 right-hand bottom-lead HSS tap in your toolkit, you’ll have a robust, go-to solution for cutting large, precise metric threads efficiently and with confidence.
