About this item
- Thread Size: M12 x 1. High-speed steel metric taps are with high hardness and toughness for wear resistance, well suited for general purpose applications.
- The thread tap 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 processing through holes or shallow holes on most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc.. Add appropriate tapping oil for higher quality internal threads and more durable taps.
- Straight flute design, rapid downward chip removal for efficient threading, clear threads without burrs, right hand tapping direction. Good for processing through holes or shallow holes
- Machine taps used with drilling machines, tapping machines, automatic machines, machining centers, CNC, milling machines, not recommended for hand and electric drill tapping. Recommended feed speed: ordinary steel: 6-15m/min; harder steel material: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min.
Features:
Taper cutting edges and M12 diameter straight threaded flute.
Used with some cutting fluid or keep it wet when tapping, the will last longer.
Suit for machine use to cut thread inside hole, creating a female surface which functions like a nut.
Taper offer a very gradual cutting action, is most often used when tapping material is difficult to work (e.g. alloy steel).

Tips:
1. 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; slow speed with high torque. The force must be uniform in tapping operations.
3. First drill the hole with twist drill, and then use the taps tapping. Tapping angle should be vertical 90 degree and keep stable.
4. Tapping depth should not exceed 1.5 times the diameter of the tap: For example: diameter of M5x0.8 about 5mm, the depth should not exceed 7.5mm.
