Hand Tap Set Size: Metric thread size: M4 x 0.7; total length: 32.5mm / 1.28"; thread length: 17mm / 0.67"; square end width: 3mm / 0.12"; accuracy class: H2. Right hand thread cutting, clear threads, fast tapping with accuracy.
2 Styles of Taps: Taper Tap: Start the thread and guide it into the workpiece; Bottom Tap: Generate threads close to the bottom of a hole. The tools are precision machined to produce accurate threads, ensuring a tight and secure fit when used to tap holes.
Wide Applications: Hand taps are mainly used with tap wrenches and are suitable for re-tapping damaged or stuck threads, or to create new threads. The threading tools are used for tapping through or shallow holes in mild steels, aluminum, iron, copper, hard plastic.
Durable & Reliable: Thread taps are made of 9CrSi alloy tool steel with high hardness, wear resistance and toughness, durable and very suitable for tapping hard materials. Straight groove design can quickly remove chips downward, reduce operating resistance, and achieve efficient processing.
Tips: Tapping oil has lubrication, cooling, and anti-sticking effects. Adding appropriate tapping oil can obtain higher-quality internal threads and more durable taps. Ensure proper alignment, use proper tapping technique, and apply consistent pressure as you turn the tap to achieve clean, precise threads.
