## Description

Heavy Duty Metal Cutting Reciprocating Saw Blades, 12-Inch 14TPI M42 Bi-Metal +8% Cobalt Reciprocating Saw Blade For Thick Metal Fast Straight Cutting, Solid Pipes, Profiles 5-PACK

Review: Great product - I was remodeling my kitchen and I needed these to cut some screws they're keeping the cabinets together that were over 5 in long. Cut through like butter.
Review: Very good - Very good item for the price. Let me be as honest as I can; the truth is these reciprocating blades don't last. They are disposable items. In general. That goes for every single Megan model of these particular blades. This is a positive review and a compliment. I'm very impressed with the price and quality of this particular item. I have been buying the same product for a while now. I like them. I admit they don't last as long as I'd like. I wish everything lasted forever. Lol. But of course I'm grateful to find these because they are strong enough to cut through truck frames. That's a good thing.

### ⭐⭐⭐⭐ Only 4 blades used to dismantle a 12' by 16' metal shed.
*by G***N on June 4, 2021*

Liked the shorter blade for the majority of the metal that we sawed thru. Worked very well with the heavier strut and corner metals as well. Even used it to chop the plywood flooring into 2' x 2' pieces for disposal. Adapter fit right into the Milwaukee Sawzall with no worries. If needed I would definitely purchase these blades again, but they were so efficient to use that I have 8 left over from this project. Great value for the $$
