Yeah, Ive had mine about 6 seasons now and the bit doesn't cut like it used to, and the replacement bits are about the cost of a whole new setup. So Im considering buying the drill adapter to squeeze a few more years of life out of the bit and save my arms for jigging. The first time I used a K drill was up in glacial lakes last year with 20 inches of ice, I didn't have lithium ion drill set up and was just using 18v dewalt, It took a battery per hole to drill. With a newer drill set up the K drill performs nicely but it doesn't wow me enough to justify buying one. The first time I used the Nils by hand, it did wow me how fast it would drill.
