These assortments contain general-purpose bits.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Designed for screws with a square recess in the head, these are also known as Robertson bits.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.
These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. Turn the collar on the driver to adjust torque. When set torque is reached, the driver slips to disengage and stop turning the fastener, preventing overtightening. Sets come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.
Note: Accuracy ratings do not apply to the lower 20% of the torque range.
