I bought it for using bit type drill with air tool. The ball that holds the bit of the holder I used to date has been weakened and it is being exchanged for use as it has been removed. It seems that there is no play in the bit holder part and it can be used for a long time. Because it is used frequently, we plan to order multiple items.
Purchased to use 6.35 bits with 6.35 square socket wrench etc. With the driver, you do not enter, there is no space, on the stabilizer, it is somewhat good for difficult to remove, when you need force, when you want to tighten firmly. With this, the range of utilization of bits expands. It is convenient to have it.
