1.Spiral Point Tap: Thread size: M4 x 0.7; thread tolerance: H2; thread length: 15mm / 0.59'; plug chamfer and right hand thread cutting. Straight flutes are ground to provide downward chip removal, with clear threads and sharp cutting edges. 2.Material Finish: 6542 high speed steel metric taps run at high speeds and generate threads quickly and efficiently, ing high hardness (HRC6264), wear resistance, and good toughness. Titanium coating for improving wear resistance, hardness, heat resistance, lubricity. 3.Applications: Thread taps are great for throughhole threads. Can be used for drilling and tapping stainless steel, aluminum, alloy steel, ordinary steel, cast iron, nonferrous metals, hard plastics, etc. Flutes on the screw tap help to remove chips and debris from the hole. 4.How to Use: Suitable for drill presses, tapping machines, CNC and milling machines. Used with tapping oil to get higher quality threads and more durable taps. The point of the tap helps guide it into the hole and reduces the torque required to turn it.
