Uxcell 3pcs Metric Hand Tap and Die Set for Thread Repair

The hand tap and die set includes 2 pieces of metric taps - 1 taper tap and 1 plug tap. The thread size is M7 x 0.75 (right-hand). The total length of the taps is 72mm / 2.83", with a thread length of 25mm / 0.98". The square shank width is 5mm / 0.2", and the accuracy grade is H2. The round die has the same thread size of M7 x 0.75 (right-hand), an outside diameter of 25mm / 0.98", and a thickness of 7mm / 0.28".

The M2 (6542) high-speed steel taps offer high hardness, good toughness, wear resistance, and excellent cutting performance. The 9SiCr alloy tool steel die provides excellent hardness, toughness and wear resistance for durability. The uncoated tap and die set delivers good cutting performance.

The taper tap is used to start the thread and guide it into the workpiece, commonly employed when tapping through holes. The plug tap creates deeper threads than the taper tap, making it suitable for both through-hole and blind-hole applications. The straight flute design of the taps provides fast downward chip removal and clean threads without burrs. The round die features a conical locking hole, ensuring strong locking and preventing looseness.

This metric tap and die set can be used to re-thread damaged or jammed threads, as well as to create new threads. It is suitable for tapping through or shallow holes in mild steels, aluminum, iron, copper, and hard plastics. The surface of the tools is lubricated with grease to prevent rust.

The tap and die set is primarily intended for hand use. The thread tap is used with a tap wrench, while the round die is used with a die stock. Applying appropriate cutting lubricant or oil during the tapping process helps achieve higher quality threads and ensures more durable tools.

To achieve clean, precise threads, users should ensure proper alignment, employ proper tapping technique, and apply consistent pressure while turning the tap and die. Periodically reversing the tapping motion helps break up chips and remove debris from the flutes, preventing clogging and ensuring smooth operation.

In summary, this versatile metric hand tap and die set is a valuable tool for re-threading damaged or jammed threads, as well as creating new threads in a variety of materials. Its high-quality construction and user-friendly design make it a reliable choice for a wide range of applications.
