IMPA 631462 HAND TAPS set of 2 pcs HSS BSP 1 1/2" x 11

This set of two taps is made of high speed steel and is intended for use on British standard pipe threads. The taps are 1 1/2" x 11 and have a number of unique features that make them ideal for use in a wide variety of applications. The first is that they are designed to cut both internal and external threads. This is possible because the taps have a flute that extends the full length of the tap. This allows for a more even distribution of cutting forces, which results in a more accurate thread. The second unique feature of these taps is that they have a spiral point. This point is designed to prevent the tap from walking or skating across the workpiece. This results in a more accurate and consistent thread. Finally, these taps are also designed to be used with a tap wrench. This wrench allows for more precise and controlled turning, which results in a more accurate and consistent thread.
