Power and WeightManufacturers break cordless drill users into two distinct groups. The people in the first group want as much power as they can get and don''t mind carrying heavier tools to get it. The people in the second group are willing to sacrifice power to get a light, maneuverable drill with superior run-time.The split makes sense. People who frame, build decks, or work in sub-trades like electrical, plumbing, and hvac drill big holes and drive lags and oversized fasteners. Only the bigger, heavier drills have the power to perform those tasks. People who do finish work like hanging doors or building and installing cabinets don''t need that much power and can be more productive with a light, compact tool.

Several months ago I was drafted into installing a few extra diffuser grilles in a religious building. As I was trying to screw the diffusers into a boot we had already installed and connected flex duct to, the thought hit me: Why doesn''t someone make a diffuser and boot that you can connect to flex duct from down below, then simply snap the whole assembly into the ceiling? Imagine my surprise to find chiagodrillpress that Airtec chiagodrillpress Products chiagodrillpress Corp. makes just such an item. Their Model MY diffusers come in two-way, three-way and four-way chiagodrillpress configurations. They can accommodate 6-in., 7-in. and 8-in. flex duct and have internal balance dampers. You assemble them below, push them into place and turn screws that spread wings above the drywall
