Question: What is the length of these blades?
Document: They seem to be decent blades but I wouldn't know they were to short. These blades only good for half inch thick stuff. No where in description does it say how long blades are. Well I got suckered and bought two packs. Now I have 48 blades and out 20 some bucks. I went to different brand that lists length. No more black and Decker blades for me even if they post length.
Nice blades. The got me through an important job.
It's a good assortment of blades for the saw and depends on the project which blade to use which will best.
I was surprised by the amount of blades they sent, and the diversity of applications you can use this saw for!
I bought these and am thrilled with the price and selection of blades. I am quite happy with this purchase.
There jig saw blades do just as advertised and are for small projects as they hold well only against thin metals and material.
So far seems to be a great set of blades at a reasonable price. The variety covers most DIY projects.
I was a little disapointed in the quailty of the blades.The metal appears thin.The good thing is there are alot of them.
I already have the saw and having extra jigsaw blades are worth buying for the price so go and buy them.
AS advertisedI would recommend. I don't have 12 more words in my vocab to embellish on the quality of these blades
Answer: yes
