Description:
1. Straight flute tap for clear threads without burrs, right hand tapping direction. Quick downward tip removal provides efficient threading and is suitable for use with through or shallow holes.
2. Screw taps are used to create new threads or recreate damaged or clogged threads. Widely used in most metals, iron plates, copper, zinc, alloy steel, polished steel, A3 steel, stainless steel etc. Add appropriate tapping oil for better quality internal threads and durable taps.
3. 6542 high speed steel metric tap provides high hardness, good durability, abrasion resistance, and excellent cutting performance. Titanium coating provides excellent corrosion resistance, improves abrasion resistance and hardness, reduces friction coefficient for smooth tapping.
4. Machine taps are used with tapping machines, drill machines, milling machines, C NC Recommended feed speed: general steel: 6-15m/min, hard steel: 5-10m/min, stainless steel: 2-7m/min, cast iron: 8-10m/min. Not recommended for manual and electric drill tapping.
Note:
1. Control the speed according to the hardness of the material. The harder the slower the speed. Use high speed with small torque, low speed at high torque. Tapping operations require even pressure
2. First, drill a hole with a twist drill bit, then tapping with a screw tap. Tapping angle must be 90 degree vertical and stable
3. The tapping depth should not exceed 1.5 times the diameter of the tap(i.e. the diameter M5x0.8 should not exceed 7.5mm and the depth should not exceed 7.5mm)
