Spiral Flute Thread Taps 1/4-20 UNC 2B Screw Threading Tap Tapping Tools

Thread Size: 1/4-20 UNC (Right Hand) Accuracy: 2B Thread Length: 20.8mm / 0.82" Total Length: 68mm / 2.68" Square Shank Width: 4.5mm / 0.18" (Round Shank Dia.: 5.8mm / 0.23") Material: 6542/M2 High Speed Steel (HSS) Finish: Uncoated Package Content: 1pcs x Spiral Flute Thread Tap Descriptions: Thread tap features spiral flutes, clear threads without burrs, and right hand thread cutting. Spiral flutes are fully ground to provide upward chip removal. Flutes on the screw tap help to remove chips and debris from the hole. 6542 (M2) high speed steel screw taps run at high speeds and generate threads quickly and efficiently, offering high hardness, wear resistance, and good toughness. Uncoated taps feature just the base substrate without any additional coatings, great for a wide range of applications. Spiral flute threading tap is suitable for processing blind holes and sticky materials. Used for drilling and tapping stainless steel, aluminum, die steel, ordinary steel, non-ferrous metals, and hard plastics. Machine threading tap is used with drill presses, tapping machines, CNC and milling machines. Used with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap chucks with overload protection. It is not recommended for hand use and electric drill tapping. Tapping angle should be 90 degrees vertical and stable. The tapping depth should not exceed 1.5 times the diameter of the tap. Control the speed according to the material hardness. The higher the hardness, the slower the speed.
