Any friction causes heat. If the blades are spinning faster than they are made to cut then they can build up heat. When I lay the auger tip on the ice it melts in pretty quick so the blades do have a raised temperature. Will the blades turn blue... no. will they dull prematurely? quite possibly.
through how thick of ice have you guys drilled with these?
I hollowed out an old battery for a ryobi 18v drill, added wires from the battery to a small 12v 9ah lead acid battery and 6v 5ah lead acid battery in series. I can drill at least 50 holes in 12'' of hard ice even with the junk ryobi drill.
my wife will be sure I'm nuts now
I have a 10 " jiffy that runs fine, but i have been thinking of trying to lighten my load by hooking up my 18v dewalt hammer drill, to the jiffy screw to only drill two holes.does anyone think this is possible ?? james
