Document: This is a good starter kit to find out which blades will work for you.
Good quality blades for various types of cuts.
the Bosch blades are excellent quality. They stay sharp and are rigid enough not to bend.
By far some of the best blades out there. Have used many and these are last longer than most and don't bend or warp as bad.
In my opinion, Bosch makes the best blades for a jig saw. They last longer than most and don't cost a fortune.
I have only used one of the blades so far but it has cut really well and seems quite tough.
Got the blades real quick and they were packaged well Product does the job as described.Thank you very much
great set of blades.they cut great compared to some other blades i had before.would buy this brand again instead of the brand i had before.
What can you say about saw blades? They either cut or they don't. These cut. Stupid word count requirement Amazon - fix this now!
Good variety/assortment. Still using all the same blades I started with, for various jobs, so they don't wear out quickly!
Answer: yes
