Review on 🔪 50-Piece Contractor Jigsaw Blades Set with Storage Case - Assorted T-Shank Jig Saw Blades for Precise Wood, Plastic, and Metal Cutting (T118A, T118B, T101AO, T101B, T101BR, T144D) by Dominic Mayo

so thought it would be a great deal. And maybe they are if they really stay in your instrument. I use a DeWalt 20v cordless jigsaw and the metal cutting blades just fall out of the machine on contact with friction. They seem to snap well - pull on them and they seem to be securely locked into the tool. Pull the trigger and they stay in place - place the bit on the metal tube and "Ring!" The blade falls out and falls to the ground. Tried several blades for cutting metal and same problem with all of them in the set. The only wooden blade we tried today worked with no issues. Maybe the side wings or lugs are just a bit wider and offer a more secure fit - I don't know and can't tell other than that they just don't stay in the puzzle and are therefore useless.
