Drywall bit

Don't have a driver but if I've got to use it in hammer I use a different sort if magnetic slider bit which stops it punching thro'. Looked at and didn't rate the W,,, ring magnet at all, or the price,
 
I don't use the black screws because of the splinters I use the zinc plated silver ones
I try to get the coarse thread screws, they don't seem to splinter and the thread is more robust. As for impact drivers, never had a problem with those metal dimple bits, the trigger is usually a variable speed, just take care
 
had a box of screws from walls and ceilings once. Swarf was ridiculous in my fingers. I could have been picked up by a high power magnet if I was in a James Bond film!
Shhhh , new magnetic swarf removing screw holder coming to the market
