Review on TOLESA 9 Inch 14TPI Heavy Metal Cutting Reciprocating Saw Blades - Bi-Metal Sabre Saw Blades For Metal Pipe, Sheet Metal, Rebar, And Cast-Iron - Better Wear Resistance - 5 Pack by Seth Hogate

Bought this to demo a door rough in opening which was too small. I needed to get between the stud and the sheating to cut the galvanized sheathing nails around the door so that I can surgically remove the studs and replace them to build the correctly sized opening. These blades were perfect for the job. It made quick work of getting in between the sheathing and the studs and also between two studs that were nailed together to cut the nail that was holding them together.It was easy to get the blade between rather tight fitting sheating. It also took less than 1/2 second to cut through galvanized sheating nails. It too about 1/2 second to 1 second to cut through 3 inch full round head nails shot from a framing nailer. The blades caused pretty minimal damage to the wood stud and the sheathing . Of course there was some surface damage where I cut but I am happy with the performance of these blades.After cutting, the blades still have a lot of life left in them. I would have been happy to demo one rough door opening and throw the blade away. The blades performed better than expected. This one is a keeper.
