M4X0.7 H2 Spiral Point Thread Tap 100Mm Extra Long HSS Tapping Threading Tool

Description: Made of high-speed steel, the tapping bit has high hardness, toughness and wear resistance, and can stably remove chips during cutting. Uncoated taps only have a base substrate, which is very suitable for a wide range of applications. Thread tapping bit features spiral point, plug chamfer and right hand thread cutting. Straight groove taps can remove chips downward, with clear threads and sharp cutting edges, ensuring fast and accurate tapping. Screw tap can be used for drilling and tapping of stainless steel, aluminum, cast iron, alloy steel, ordinary steel, non-ferrous metals, hard plastics, etc. The grooves on the tap facilitate the removal of chips and debris from the hole. Suitable for drilling machines, tapping machines, CNC machine tools and milling machines. The speed is controlled according to the hardness of the material. The higher the hardness, the slower the speed. Use with tapping oil to improve processing accuracy and reduce the probability of breakage. It is recommended to use a machine tap with a tap chuck with overload protection function. The tapping angle should be 90 degrees vertical and stable, and the tapping depth should not exceed 1.5 times the tap diameter.
