Question: Which is better? A shear or a nibbler? What will one do that the other can't? Kind of confused.
Document: I am a professional carpenter/remodeler and have done some metal roofs before, but never one with hips and valleys. This was the first metal nibbler I have owned, so I can't compare it to others, but it worked well on the first job. I bought it for the price, but the quality has been beyond my expectations. I used it cutting metal roofing sheets on angles for hips and valleys.
Much better than I thought possible. Great for installing furnaces. Saves a ton of time well worth the money. Buy one.
I'm a contractor and have a shear but I never use it any more. Spend a little more and buy the nibbler.
The Makita JN1601 5 amp 16 gauge nibbler is one fantastic tool. It fits the hands nicely and was easy to handle. If you are putting up metal roofing or siding you diffenantly need this tool. The JN1601 exceeded my expectations. The nibbler is as awesome tool.
It cuts straight and fast. I am well satisfied. A very good product for the money.
This thing will cut circles around the Hitachi that i used to own.I am glad I spent a little extra to get much better quality
Great tool. Love it. How did I live without it? A real money maker. Light, versatile, gets the job done. I'm a professional.
Here's one of those tools that you don't think you'll use to often but it really comes in handy. cuts easily through but aluminum and copper. Even cuts through a soldered double lock of 16 oz. copper, that's 4 layers of copper and solder without a hiccup. standing seam roof and 5v ribbed roofing also no problem
this is the best nibbler i used and i use a lot of brands easy to use cut well .will buy another
I am building a barn on my property. Received the nibbler and it cut my time to fit metal by 75%. I installed R panel and it zips through the straight cuts like a knife through butter.
Answer: yes
