1. Metric Spiral Groove Tap: Thread Size: M5 x 0.8 (Right Hand), Accuracy: H2, Total Length: 100mm (Extra Long), Thread Length: 21mm, Square Shank Width: 4mm. Spiral flutes are fully ground to allow chip removal upwards, with clear threads and sharp cutting edges. 2. 6542 (M2) Speed Steel: Runs at speeds and produces threads quickly and efficiently, providing hardness, wear resistance, and good toughness. Titanium coating provides corrosion resistance and reduces the friction coefficient for smoother tapping. 3. Applications: Taps are ideal for working with blind holes and sticky materials. Used for drilling and tapping stainless steel, aluminum, alloy steel, ordinary steel, cast iron, nonferrous metals, hard plastics, etc. The grooves on the tap help remove chips and debris from the hole. 4. Machine Tap: Suitable for drills, tapping machines, CNC, and milling machines. Used with thread oil to obtain higherquality threads and more durable taps. Machine taps are recommended for use with a tap chuck with overload protection. Not recommended for hand use or electric drills.
