Sheet metal nibbler vs. shears
I have noticed there are two types of cutters for sheet metal. One a
nibbler, one a shear. The one nibbler I see apparently cuts out small pieces, almost circles, and imagine that would be for very fine work. The other "nibbler" has two blades that are about 3/4" long that go up and down, pinching and shearing the metal. The third is a shear, much like a pair of electrified scissors. A brief description of each and its use would be appreciated. When it comes down to it, I will probably need all three for various stuff. And lastly, I see some run on air. If one has a good compressor, is there any important differences between the electric and air models? This is going to run a few bucks, so wanted to ask first. And is buying refurbished worth the savings or not? Problems later vs: new? Steve |

This one: http://www.grizzly.com/products/Pneu...Nibbler/T23085 punches out crescent-moon shaped chips with devilishly sharp points. Mine's inaccessible behind firewood now. IIRC you can't directly see the cut line and have to offset the guide or drawn line. They cut fairly tight curves. http://metal-engravings.com/wp-conte...al-Tools04.jpg has two stationary blades straddling one that pivots up and down, like twin scissors. It's the one that sometimes jams on me. They cut larger diameter curves. If you make blind cutouts with them the corners will need cleanup. I haven't tried other hand-held powered versions. And lastly, I see some run on air. If one has a good compressor, is there any important differences between the electric and air models? Mine are all air so I don't risk sharp edges or splinters cutting into a power cord. This is going to run a few bucks, so wanted to ask first. And is buying refurbished worth the savings or not? Problems later vs: new? Steve No idea. Mine are cheap imports that don't get much use. jsw |

I find that the hand shear is easier to control where it fits. 2) the little crescents of aluminum go everywhere. Not a problem if you're working on the bench. But if you were working in an electrical box, those conductive chards going everywhere would be a disadvantage. You might want to ask about the availability of replacement die. I'm quite sure that I won't be able to get a replacement when my HF unit gets dull. |

I got two variable speed electrical ones at an auction sale at an aircraft repair shop. These allow you to see where you are cutting and allow all kinds of curves, etc. Actually cut faster than I like! Just need to practice! Paul |

And is buying refurbished worth the savings or not? *Problems later vs: new? Steve Just depends on what you want to cut and to what accuracy. I've got the pneumatic nibbler that cuts the little partial circular nibbles, like the other poster said, they're nasty sharp. Takes quite a hole if you want to start in the middle of a panel. The other nibblers I have are hand-powered, good for small stuff like the electronic chassis and circuit boards they were designed for, not so great for roofing sheets. You can follow a line quite closely with those, the handle is under the work surface and you can see the punch very easily. They will cut to a sharp corner. Any of the nibbler types need to have sufficient material allowed for when laying out for filing, the cut tends to be ragged. Punch sets can be had for both types, you just have to dig around to find them. The small hand nibblers only take a 1/4" hole to start in the center of a workpiece. The electric shears I'm familiar with can do the job, but like hand shears, they'll distort the material edge while doing it. People tend to crowd the limits of what they can handle, leading to busted blades and sometimes busted innards. Blades sets, when obtainable, tend to be a little expensive. I see a lot of the shears in the pawn shops with one blade gone, good luck finding a replacement. Every OEM has its own design. I don't do a lot of compound curved sheetmetal work, if I did, a set of the rotary wheel shears would be nice, I believe the formal name for those is "Beverly", you see them used a lot for aircraft work and making custom car body parts. Only worth it if you do a lot of it and can take the tool cost off the taxes. For a lot of things, the fastest way is to get out the angle grinder, equip it with a thin metal cutting blade and go to it freehand. I had a brand of wheel called "Razorblade", were like super Dremel cutoff wheels on steroids. Just about that thin, too, but stood up better. I bought what that weld shop had on hand, haven't found them anywhere else. I've got a "shoe" for the 4 1/2", looks like the base for a Skil saw and works the same way. Kind of a pain to put on, so not really worth messing with except for long cuts. It does keep the spark tail down. Fewer holes in shirt and pants. Stan |

The cut tends to wander off the line because I keep my head as far away to the side as possible. Sometimes the job is easier and neater if I grind a shallow groove the length of the cut first and then follow it with a severing cut. jsw |

Beats trying to manage a 4x8 or 4x4 sheet of 16 ga. though the B3 by a mile. Recently someone gave me a cheap Chinese air nibbler. It never worked right and I threw it away after determining that I couldn't figure out how to make it right. Now that I have air, I use one of those two-prongs-up, one-prong-down bits for an air chisel/hammer on light stuff with excellent results. -- Mike Spencer Nova Scotia, Canada |

I inherited a radial arm saw that just might be up to the task, but may only cut half of the sheet at a time, and I would have to build a table to secure the entire sheet to keep from launching it. I hate cutting this stuff with a circular saw, although it has been suggested by others. I will only do it when no other way is possible, or it is a small cut. Right now, I'm ready to order a DeWalt W890 for the straight work, and am deciding on a nibbler and handheld anvil type for finer work. Steve |

Bob I have tried a standard metal cutting blade, and it's just a lot of noise, sparks, and it eats one blade per sheet. I do hear you that there is a different blade that might be my answer. I will have about a $600 outlay here in steel alone, and if this blade will do the simple job I need, it will be worth it. I will need the other type shears and nibblers for other type of work I'll be doing. But this will get me past this stage of the project. Steve |

One a nibbler, one a shear. The one nibbler I see apparently cuts out small pieces, almost circles, and imagine that would be for very fine work. The other "nibbler" has two blades that are about 3/4" long that go up and down, pinching and shearing the metal. The third is a shear, much like a pair of electrified scissors. A brief description of each and its use would be appreciated. When it comes down to it, I will probably need all three for various stuff. And lastly, I see some run on air. If one has a good compressor, is there any important differences between the electric and air models? This is going to run a few bucks, so wanted to ask first. And is buying refurbished worth the savings or not? Problems later vs: new? Steve Hi Steve, You should check out this video on youtube https://youtu.be/M2ceCfijw-0 Beverly Shear B1 It's the best bench top sheet metal shear I've seen. Expensive and tough to find, but very versatile! Does anyone have any experience with the HF version of the Beverly? It's just $139 on sale right now. I've been enamored of the Beverly for decades now, having used one once, in another life. They are not bad. Need a Beverly? I find them every now and then. Yes, grab one for me (cheap to free) for the next trip, please! Next year? Gunner, who hopes your trip home went well. It did. Nobody stole anything out of the back of the truck, and only one bucket overturned, spilling cutoff material all over the floor of the bed. Luckily, it was all larger than the gap at the tailgate, or I would have had a major lawsuit on my hands as small pieces of steel bounced into windshields and punctured tires all along I-5. g Couldn't find a 1" micrometer or the odd pair of parallels, eh? Oh, and you didn't even mention the Current Project Trailer. bseg Oh ****...sorry about that. I couldnt find your various emails..missed the micrometer(s) and parallels. Those however I can ship cheaply. Crom knows Ive got enough mics..though am short on extra parallels https://picasaweb.google.com/1040422...2602/Metrology Anything else in the above link you need? |

Expensive and tough to find, but very versatile! One of my best scores ever was finding a Beverly B3 cheap when I was on the road with a backpack. I went over to the nearest hardware store for a spool of twine and a suitcase handle. Put the B3 lever in my pack, lashed the suitcase handle to the shear and finished the trip with the B3 as luggage. I have a Bosch nibbler that's good for up to 16 ga. steel. Makes a nice cut but I find it real hard to follow a line, either drawn curves or straight with a clamped-on guide. I use it mostly for whacking a rough piece out of 16 ga. that will be less awkward to manage than a 4x4 or 4x8 sheet, then take the rough piece to the B3 to cut the finished shape. Blades need sharpening after 35 years, leaves an annoying burr that it didn't used to. Oh, and the nibbler leaves these horrible little pointy crescents of steel all over the place. Go for a Beverly if you can find one to match your budget. -- Mike Spencer Nova Scotia, Canada |

It is just that statements that are not correct grate on me just the same as misspelled words or wrong punctuation grate on other people. Dan |

Go for a Beverly if you can find one to match your budget. How flat does steel cut in a shear like that come out? Any curl at all? For pieces several inches in both dimensions, very little. A kidney- or rose-petal-shaped piece half the size of a place mat in 16 ga. comes out pretty flat. For making narrow strips, e.g, 1" x 20", quite a lot. Annoying, but my old cast iron 3' treadle shear won't do 16 ga. Always use it for straight cuts in lighter material. -- Mike Spencer Nova Scotia, Canada |
