You’ll find a circular saw in nearly every Pros arsenal. Corded models offer nearly infinite power as long as electricity is hooked up or there’s a generator nearby. And with most models offering a 15-amp motor, you get reliably solid power. Even the DIY models can make an effective cut with decent speed using an excellent blade. Around the country, these benefits make Pros keep choosing the cord over cordless convenience. Plus, corded tools don’t force you to stick with one brand’s battery platform – you can get the best tool in each class no matter who makes it.
Bosch CS5 120-Volt 7-1/4-Inch Circular Saw
When one of these drills is jammed – put into a bind-up situation – applying power to the motor will not free the bit. Some of these new cordless tools have power to spare, and sudden high-torque movements rotate the drill … and the operator's wrists and arms. This at the least is tiring. It can be dangerous. Sometime the tool will twist out of the user's hand, swing around and hit the operator or someone close to the tool, causing bodily harm. Bosch CS5 Manual
One real complaint; when you're cutting right-handed, the dust is directed right into your shoes and nailbags. The blade-left saw doesn't have a Bosch dust chute accessory available, and this saw really needs one. When you're cutting a post from right to left, the dust is projected straight up, into your face and eyes. Bosch needs a dust chute for the CS-5. I tried the dust chute for cs-10 and cs20, but it doesn't really attach to the CS-5 without major modification. It's a short-coming.
