I have a StrikeMaster Laser Mag Express Auger. I'm very happy with the weight,and overall performance but I'm very disappointed with the quality of the blades. Seems if I even look at them the wrong way they get dull. Costing me 131.87 a year for 2 sets of blades and 2 power points. I'm not applying any pressure while drilling. Am I alone on this or is anyone else experiencing a simular situation ?
