■ This is used to cut a comparatively soft material, such as <2D aluminum, and create an internal thread for accommodating a helical coil wire screw thread insert, in order to reinforce Nitride the internal thread and increase durability. Recommended Tapping Speed depending on Materials ■Oversize taps of Ib+30 are also available to allow for shrinkage of internal threads.
