BOSCH OSC4F 4-Inch Bi-Metal Multi-X Segment-Blade

These are the best for cutting fiberglass. Makes my boat projects way easier with less dust. And I put a lot of pressure on them and they last a very long time. Soft metal is ok, don't try hardened steel, you need carbide for that.

Used blade to cut bottom of steel clad door and needed a little bigger than the standard 3" blade. It did the job but most of teeth broke of or worn off at end of job. Considering price I wont use this blade again when cutting metal, if it will only last for one job.

This blade is good and works well. But do not expect it to last very long and, as you probably already know, the price is pretty high. I think that Bosch thinks very highly of their products.

Bosch quality seems to be very good. Huge time saver. Some tasks would be nearly impossible to perform without this tool.

IS A VERY FUNTIONAL AND GOOD QUALITY
