기능

• For parts made of relatively soft materials such as aluminum, internal threads for insertion of insert coils are processed to reinforce internal threads and increase durability.
• Since the diameter of the internal thread used to insert the insert coil is larger than that of the external thread used to insert the coil, the diameter of the insert coil tap is larger than its nominal diameter.
• Since the diameter of the pilot hole also increases, use an appropriate pilot hole diameter.
• Since the shank part is large, use it with an appropriate holder.
• There is also an Ib+30 oversize tap with internal thread shrinkage.
• Work Material: Aluminum Rolled Material, Aluminum Alloy Casting, Zinc Alloy Casting.
