I got a Mastercraft Corded Hammer Drill from Canadian Tire hardware store. It came with a small tool-pen (don't know what to call it). In the picture below, the pen is in between the tool box and my laptop. On the one side, it has a slot to insert screw tips. And on the other side it has a stainless steel head (again, don't know technical term for this).My big question - How am I supposed to use this?Till now, I'm directly inserting the drill bits and the screw tips to the drill and it works quite well already. So what is the use of this pen at all?I would like to have a hand screwdriver that can take replaceable bits for assorted tasks. I was wondering if this pen can be used a hand driver, but no, because it doesn't have a grip.http://ift.tt/2h3Xkjq via /r/DIY http://ift.tt/2vUoU8U
