4pcs Metric Machine Tap M2.5 x 0.45mm M3 x 0.5mm H2 HSS Uncoated 3 Straight Flutes Thread Tapping DIY Tool

Key Features

• Thread Size M2.5 x 0.45mm, M3 x 0.5mm. High-speed steel taps are with high hardness and toughness for wear resistance, well suited for general purpose applications.
• Can make new threads or re-thread damaged or jammed threads. Uncoated taps feature just the base substrate without any additional coatings, and fit a wide range of applications.
• Suitable for most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc.. Appropriate addition of coolant (e.g., water) can extend the service life when tapping.
• Standard metric thread design, clear and tidy, provide rapid chip removal for efficient threading.
• The mini metric taps are mainly used for clocks, watches, low hardness wood and soft metal hole processing.

Recommended hardness of tapping material is not too high: Suitable for most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc. Appropriate addition of coolant (e.g., water) can extend the service life when tapping.2. Please control speed according to material hardness. The higher the hardness, the slower the speed. Fast speed with small torque; the slow speed with high torque. The force must be uniform in tapping operations.3. First drill the hole with a twist drill, and then use the taps tapping. The tapping angle should be vertical 90 degrees and keep stable.4. Tapping depth should not exceed 1.5 times the diameter of the tap: For example diameter of M5x0.8 is about 5mm, and the depth should not exceed 7.5mm.
