Blades work well and cut desired materials effectively.I purchased two of these Imperial extended reach blades to use with my Dewalt 20V oscillating tool where the depth of cut needed is too much for a standard length blade. I sometimes run into this when cutting in electrical boxes for flush mounting outdoor receptacles. These blades give the extra length needed to finish the cut and save me another trip to the truck to get a reciprosaw with a longer blade to finish the job. The blades are decently made and holding up well. I've been using Imperial blades with my oscillating tools for a couple of years for wood and plastic pipe and have been happy with them. These extended cut blades are performing as well as their standard blades have for me so I will definitely be purchasing them again.This blade is longer than most and that is very handy. Imperial blades are made in the USA which is awesome and well worth it to buy in bulk. It lasts a while and can really get in there compared to other blades.The extended length of this blade made the plunge cuts preciseThese are only rated for WOOD only - they are NOT rated for nails - 10 pack - all wood only. IBOA133-10 Imperial Blades.As describedit does what the video showsWears out quick on hard or 2” 2x4’s. Its easy to install and remove and the extra length really helps.Only long bit I’ve found. They work great
