From time to time we receive a new tool at the station with limited info. A while back we received two saw blades, the diamond blade and the "nugget" blade. We all had our opinions about what we thought they'd be good for but we took them out for a test run anyway.
Diamond Blade
Aggressive Random Carbide "Nugget" Blade

This video compares the diamond blade and the nugget blade on various roofing materials. The first blade in the video is the diamond followed by the nugget. The diamond blade was about 20 seconds slower and seemed to slow down in the wood. The nugget blade slowed down on the thicker metal but was more effective overall.
Here we tested both blades on thick metal. The nugget blade bounced around a lot but got the job done. The diamond blade was much more smooth and efficient though. The nugget blade is really designed for thinner metal. It will cut thicker metal, but throws large chucks of debris and can damage the blade. The cool thing is if the blade dulls you can flip it over and you have a new blade.
In conclusion, we decided to keep the saws as we had them. One with the diamond blade for forcible entry (outboard) and the other with a nugget blade for taking to the roof (inboard).
The diamond blade is great for almost all metal and masonry but not wood.
The nugget blade is great for wood and thin metal (up to 3/16") but not masonry.

Forcible Entry Saw- Outboard
What is your experience with these or any other saw blades?
Great video Vandy!
ReplyDeleteThis is such a great blog--Thanks! We'll be going through all the postings as a school at the station.
ReplyDeleteWe've had a problem with the nugget blade seriously binding in tar-and-gravel. To the roof we take the diamond and the Ventmaster.
The nugget blade throws some nice sized wood shrapnel also. We talk about it's best usage on aluminum garage doors and run an abrasive wheel blade for metal and heavy gauge metal. The DAX blade (nugget) also states what it's made to cut on the label on the wheel.
ReplyDeleteJust some stuff we figured out, thought I'd share!
