6 Inch Bits
Perfect length for the job that uses long screws. I easy to install to the drill. Work great on large wood columns.

Poor quality drills
Useless drills. Poorly made, weak material. Cannot drill even remotely accurate holes, they flex excessively and are supplied already dull. Waste of money and time.

Warning... Dangerous!! Do not purchase!
These flimsy things bent and broke, while in the drill, from only the centrifugal force of the tool. The schrapnel from this low quality POS flew outward and cut my arm. Beware. Longer is not better if there is no structural integrity to back up the length. If I could give it a 0 rating I would.
