I just bought one of these saws, but from Rockwell direct on a 3 payment plan. I am very well impressed with the saw except for one minor feature. It is a plunge action saw with no way to set and lock blade depth like a circular saw. It does have a sliding lock to prevent the plunge action past a set depth though. I used it yesterday and it is fairly light and easy to handle, powerful, well balanced and the blade that came with it went through a piece of 3/4 Oak like a hot knife through butter. It also uses a standard 3-3/8 diameter blade. It has a laser light that is dead on the money even though I use a guide to cut all my wood. It also has a trigger just in front of the power trigger to unlock the plunge action which is actually a good idea. If you want to make a plunge cut in the center of a board all you do is set the saw down on the board, start the saw, depress the trigger, hold on tight and slowly plunge the blade into the wood. It only cuts to a depth of 1-1/16 of an inch which is more than enough for 90% of my needs.
Now then, I managed to defeat the plunge action and can lock in the blade to a certain depth. The saw has 3 roller bearings on each side in a track to guide the plunge. I removed one of the bearings, put a 1/4 inch lock washer in the track, tightened the screw and the washer holds the blade where I set it. Needless to say if I ever need to make a plunge cut all I do is remove the washer. Amazon.com: Rockwell RK3440K VersaCut Circular Saw: Home Improvement
When something is advertised as being foolproof there is always a better class of fool that comes along to prove them wrong.
