Drill It

I got these hex drill because regular drills in the Hart drill I bought just spun in the housing, even if I used wrenches to tighten them they would spin. These hex drills are exactly what I needed. I drilled the shed door and a piece of flat metal and bolted the spring to the door because of wind it was tearning the screws out.

These drills fit in my Milwaukee impact driver perfectly. They were immediately useful in my deck repair project. The clear plastic case is a bonus allowing me to confirm that drill bits are all in place in the case.
