After determining the torque tool, select a bit according to the following instructions:
1. Select root shape from A to H.
2. Select the edge shape and then decide the bit model to be used.
Ex. If you select RTD120CN with the root shape C and the point shape plus bit #1, then, you should choose No. 106.
※Bit root shapes A, D, E, F and G are Tohnichi special-purpose bits. B, C and H bits are available in the local market and can be used.
