Was out in the shop yesterday putting up tools ( the rainy weekend was driving me crazy. Had to get out and do something)
I grabbed my Dewalt right angle heavy duty 1/2" drill and noticed the cord was all dry rotted and cracked. I bought this drill in 93 to put coach lanterns on Mom's front porch. About that same time I was replacing cords on dad's and grandpa's power tools. Nothing last for ever.
