Well I took my Bauer 4.5"/7 Amp/11000 RPM Angle Grinder back to HF and got a refund.
I hadn't used it any so it was still in new condition.
I just got a Dewalt DWE 4011 and very happy with it. It came with 1/4" Thick Metal Grinder Wheel plus I bought a Flap Wheel. First sharpening job on my mower blades turned out great!
Also so re-leveled my Husq mower deck and boy! that thing is cutting smooth. Ye Haw!
