I have been very happy with the quality of these blades. Although Imperial was purchased by Milwaukee Tools, I hope they do not change The performanceNot the best blades they wear out quick.Great product, and quick delivery time.Great price and great product. We have used many different types of blades these hold up nicely and are half the price of the leading brands at home depot and Lowes.nice toolsuper fast cutting and durable!Careful, this thing severed right off at the seam. Got lucky, missed my face by a hair. Probably used about 5 times before it happened, mostly drywall cutting so hardly any wear and tear, no reason for this to happen except for poor quality.I found these blades wear just as fast as cheaper ones. The holes don't seem large enough for my blade quick release to fully close.
