Most pro carpenters here in Missouri have always used a Skill wom drive saw. Mine is around 25 yrs old and still working well. Since I help another retired carpenter two days per week with a small home repair business, we've been operating with his cordless tools. His are made by Milwaukee, and seem to be durable good quality tools. His set includes a circular saw, sawzall, hammer drill/drill, and impact driver. We've used them for all sorts of jobs. I've owned a pair of Makita impact drivers for three years now, and, have had great results with these. Batteries on all the cordless tools have improved over the years. Longer run time, quicker charge, and lighter weight. I have noticed his cordless circular saw will bog down when we've ripped 2x10s or 2x12s. Here, the old worm gear saw easily outperforms the cordless saw. Since I'm old and tired now, I've thought about buying a set of cordless tools. I'm partial to Makita because of the good luck I've had with they're impact guns. For those that have used cordless tools, is there a brand you like the best? Which ones have you had the best luck with?
