Designed for Reliable Metric Threading

This M3 tap is designed around the standard 0.50mm metric coarse pitch and a 60° ISO thread profile. The Form B lead distributes the cutting action over approximately 3.5-5 pitches, helping the tap enter the prepared hole progressively. For this M3 size, Maykestag specifies a 2.5mm tapping drill diameter, an overall length of 56mm and a thread length of 10mm. Correct alignment, suitable lubrication and the appropriate cutting data are important for achieving accurate threads and dependable tool life.
