A:  Yes, you can use it on drywall. I bought these to use with a cordless screwdriver for small drilling jobs. What I've found is it works well on soft materials - like drywall - but doesn't work well on harder materials because there's too much wobble of the bit in the screwdriver chuck. That also makes the drill bit prone to snapping off from the base, if the bit is small and the material is hard.

A:  Yes. These should work very well on drywall.

A:  Just got this today, I noticed that the hex shank appears to be attached to the bit with what looks like a pin (as opposed to the competitors "pinched" - those divot you see at the hex shank). Sizes 1/16 - 1/8 are secured with one pin; sizes 9/64 - 1/4 have two pins opposite each other. I just cannot tell whether those pins goes through the bit itself. 5/16 to 3/8 the shank are machined from the bit.

A:  I can’t say how they are put together, I haven’t had any separate. The only problem I have had is in the quality of metal used. They do not hold a edge well and dull quickly when drilling in metal. I thought they would have held up better. They are ok for home owner use, but not to well for service men performing maintenance work.
