My Strikemaster has always drilled very well. Only 10 months old. Never needed any downward pressure from the opperator. This weekend I set out drilling a bunch of holes. I drilled 30 holes in a row and the first 5 holes the auger cut like it always has, at the 6th hole, it cut like crap. I had to put a decent amount of pressure on the auger to cut a hole. A couple of things to add;
1.) There was no ice build up at all on the blades/auger.
2.) Blades weren’t loose, and I got a wrench to make sure they were tight.
3.) I didnt hit bottom of the lake, I was in 15ft of water.
4.) The blades didn’t have a burr, chip or anything wrong with them.
5.) The centering point was tight and very sharp.
My guess is that the blades have something wrong at the microscopic level and new blades will solve my issue. But I have heard of augers losing the correct blade pitch and needing to be adjusted.
Any advice?
