Machine taps (spiral thread taps). The taps are designed so that 1 tap can be used instead of 3 for hand cutting. The machine tap is guided so that it is not subjected to the heavy side loads that hand taps receive. Therefore, machine taps can be made of very hard and durable material, which can better withstand higher cutting speeds.
