I bought this drill with a 6" saw and was very disappointed. This drill replaced an old 14.4v drill that I used professionally. Use it at home, 19th century .7 runs rougher, sparkles a lot and has a non-brand cartridge that jams (unlike the Jacobs cartridge on 14.4. The curves are tight again. The only advantage the 19.7 has over the 14.4 is the reset of the Battery. Like other users on this site I have gone through many batteries. I have burned 3 batteries and a charger in 4 years. The only positive thing I give this product is the performance that has saved the drill from a star. Nobody seems to make more of a quality cordless drill and everyone has downgraded their products for sale by Home Depot / Homeowners It's a coincidence that Porter Cable drills have gone down in quality than someone else started making them abroad?
