The pocket in the screw head no longer looks like a plus sign (+). About a half an inch from being completely driven, the bit cams out again.I press harder and continue driving the screw.It starts to grind out the Phillips pocket in the screw head. Since I’m not pressing hard enough, the Phillips bit cams out.I insert the hex bit and tighten the chuck.So I have to use the black sleeve to open the jaws a bit. The bit I drilled the hole with is 3/16″.I grab my Phillips hex bit and try to insert it into the chuck.Rooting around in the grass and sawdust, I find the drill bit and put it in my pocket so it won’t get lost again.I curse (remember, I was a carpenter then).Being round, the bit rolls off said surface.I take the drill bit out of the chuck and lay it down on my jobsite work surface.First, I drill a screw hole, using a twist bit.Here’s the process I followed when I still worked for a living: So, by switching bits, we could drill holes and drive screws, both while using the same drill. That means they can be easily gripped by our chuck’s jaws. Remember when I told you that the front of our drill chuck has 3 jaws? Well, these driver bits have 6 sides on their bases (hex shaped). Then, someone came up with the idea of driver bits. Have you ever driven, by hand, a long screw into wood? That’s how you get big forearms. I don’t think there were impact drivers, even then. In the 80s and 90s, I was doing a lot of framing and remodeling. Since he was there, we had to wait until later to sneak in to look at his calendars. Brrrrrrr! That’s how we knew he was there. His impact wrench used compressed air and was really loud. I remember walking past the neighbor’s garage and hearing him taking lug nuts of his car’s wheels. When I was a kid (no, I didn’t know Moe), I don’t think we had these impact driver things. Impact Drivers and the New Chuck More History Now drive your screw into the hole you just made.If you are strong enough, the bit will stay where it’s supposed to. Now turn the black sleeve the other way.When the jaws are far enough apart, stick the dill bit in.(Depending upon your model of drill, you may also need to hang onto the sleeve behind the black sleeve.) I always forget which direction you turn the sleeve.
