The DeWalt 364K 7 1/2 inch saw is replacing a DeWalt 369 model that I had for the last ten years so, I expect the same service life. I built a house with the model 369, dropped it from the rafters onto a concrete slab three times; never bothered the operational abilities. Now, I'm building a large wooden boat and wanted to treat myself to a new saw that had more options; like adjusting the blade depth and angle. I located both the same old model and Model 364K on amazon. Model 364K costs about forty dollars more, but what a difference in the power to cut through wood, ease of changing blades, and of adjusting the bevel angle and depth of cut. I also like the heavier duty electric cord. If the saw lasts for ten years, I'll be very satisfied.
