uxcell 4pcs Metric Spiral Point Thread Taps, M4 x 0.7 H2 Nitride Coated Screw Tap, Fully Ground High Speed Steel 6542 Machine Tapping Threading Tool

uxcell 4pcs Metric Spiral Point Thread Taps, M4 x 0.7 H2 Nitride Coated Screw Tap, Fully Ground High Speed Steel 6542 Machine Tapping Threading Tool

Metric Spiral Point Taps: Thread size: M4 x 0.7 (right hand); tolerance: H2; thread length: 12.9mm / 0.51"; total length: 56.5mm / 2.22"; square shank width: 3.8mm / 0.15". Straight flutes are fully ground to provide downward chip removal, with clear threads and sharp cutting edges. 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. Applications: Thread taps are great for through-hole threads. Can be used for drilling and tapping stainless steel, aluminum, alloy steel, ordinary steel, cast iron, non-ferrous metals, hard plastics, etc. Flutes on the threading 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. The point of the tap helps guide it into the hole and reduces the torque required to turn it. Tips: Machine taps are suggested to be used with tap chucks with overload protection. It is not recommended for hand use and electric drill tapping. Drill the holes with a twist drill bit first, then tap with a thread tap. The tapping angle should be 90 degrees vertical and stable.

Metric thread tap features spiral point, plug chamfer and right hand thread cutting. Straight flutes are fully ground to provide downward chip removal. The point of the tap helps guide it into the hole and reduces the torque required to turn it.
6542 (M2) high speed steel screw taps run at high speeds and generate threads quickly and efficiently, offering high hardness (HRC62-64), 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 point tap is suitable for through-hole threads. Used for drilling and tapping stainless steel (below 30HRC), aluminum, die steel, ordinary steel, non-ferrous metals, and hard plastics. Flutes on the screw tap help to remove chips and debris from the hole.
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.
Drill holes with a twist drill bit first, then tap with a thread tap. Tapping angle should be 90 degrees vertical and stable. The tapping depth should not exceed 1.5 times the diameter of the tap. Control speed according to the material hardness. The higher the hardness, the slower the speed.
