4pcs Spiral Flute Thread Taps, M2.5 x 0.45 Nitride Coated Metric Screw Tap, Fully Ground High Speed Steel 6542 Machine Tapping Threading Tool for Machinist Thread Repair

Key Features

• Metric Spiral Flute Tap M2.5 x 0.45 metric thread, H2 tolerance (accuracy), right hand thread cutting. Spiral flutes are fully ground to provide upward chip removal, with clear threads and sharp cutting edges. Flutes on the screw tap help to remove chips and debris from the hole.
• 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. Can be used for drilling and tapping stainless steel, aluminum, alloy steel, ordinary steel, cast iron, non-ferrous metals, hard plastics, etc.
• 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. Control speed according to material hardness. The higher the hardness, the slower the speed.
• 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. The tapping angle should be 90 degrees vertical and stable. The tapping depth should not exceed 1.5 times the diameter of the tap.

Descriptions

1. 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.2. 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.3. Spiral flute tap is suitable for processing blind holes and sticky materials. Used for drilling and tapping stainless steel (below 30HRC), aluminum, die steel, ordinary steel, non-ferrous metals, and hard plastics.4. 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. Control speed according to material hardness. The higher the hardness, the slower the speed.5. Machine taps are suggested to be used with tap chucks with overload protection. It is not recommended for hand use and electric drill tapping. The tapping angle should be 90 degrees vertical and stable. The tapping depth should not exceed 1.5 times the diameter of the tap.
