uxcell 4pcs Metric Spiral Flute Thread Taps, M8 x 1.25 H2 Screw Threading Tap, Nitride Coated 6542 High Speed Steel Machine Tapping Tools for Machinist Repair

Thread Size: M8 x 1.25 (Right Hand)Accuracy: H2Thread Length: 22.6mm / 0.89"Total Length: 69mm / 2.72"Square Shank Width: 4.9mm / 0.19" (Round Shank Dia.: 6.1mm / 0.24")Material: 6542/M2 High Speed Steel (HSS)Finish: Nitride CoatedPackage Content: 4pcs x Spiral Flute Thread TapsDescriptions:Metric 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. Nitride coating increases hardness, enhances wear resistance, and reduces friction for longer service life, resulting in smoother, faster tapping performance.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.

• Metric Spiral Flute Tap: Thread size: M8 x 1.25 (right hand), accuracy: H2; thread length: 22.6mm / 0.89"; total length: 69mm / 2.72"; square shank width: 4.9mm / 0.19". Spiral flutes are fully ground to provide upward chip removal, with clear threads and sharp cutting edges.
• 6542 (M2) High Speed Steel: Run at high speeds and generate threads quickly and efficiently, offering high hardness, wear resistance, and good toughness. Nitride coating increases hardness, enhances wear resistance, and reduces friction for longer service life, resulting in smoother, faster tapping performance.
• Applications: Thread taps are great for processing blind holes and sticky materials. Used for drilling and tapping stainless steel, aluminum, alloy steel, ordinary steel, cast iron, non-ferrous metals, hard plastics, etc. Flutes on the screw tap help to remove chips and debris from the hole.
• Machine Tap: Suitable for 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. Not recommended for hand use and electric drill tapping.
• Tips: 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.
