Nibbler attachment

[ErrolFlynn]

Nibblers seem to be quite expensive. I've never actually used one before. It's not the sort of thing I'd use often. So, I'm reluctant to pay a lot for something that only gets a few weeks' work. I don't use sheet steel much at all. I wonder if anyone has experience with the nibbler attachment that can be used with an electric drill. A cheaper option. How have you found them? This sort of thing:

P&N were a good make, I thought, but the reviewers on that site give it the thumbs down.

What do you actually want it for? Nibblers are generally used for cutting out curved surfaces; they are pretty ordinary at keeping long straight lines. Those Bunnings reviews were predominantly around cutting sheets of Colorbond; I used a circular saw with an Austsaw sheet steel cutting blade (https://www.austsaw.com.au/rotary-hacksaw/) for rebuilding the front of my shed; highly recommended.

Again depending on what you want too cut with it,
Have you considered Aviation snips or a good pair of Tin snips.

There not too difficult too get use too.

the nibbler leaves a gazillion little bits of metal to pick whereas the shear cuts

You can buy 'vermin guards' but they are not cheap. I figured all I'd need would be a nibbler and some sort of template to guide it to the correct profile. And bending a piece of sheet metal shouldn't be too difficult.

[ErrolFlynn]

Tin snips would be fine (I have a pair) but given the shape I want the metal cut I think the nibbler would be best, but I have to admit to wanting the cheap option (ie. the elec drill accessory).

I used this nibbler to cut a round hole in a corrugated iron roof for an air vent in my shed:

DETROIT 500W Nibbler DEN5001 | Total Tools (https://www.totaltools.com.au/78011-detroit-nibbler-500w-den5001)

It cut like a hot knife through butter and I was very impressed with how easy it was to follow a curve and how little time it took.

However it was very loud and created a shower of fine, sharp metal offcuts to clean up after (still finding the odd piece 1 year later...)

[Skew ChiDAMN!!]

Years ago I used one ext5ensively for quite a few roof penetrations on colourbond.

It worked wonderfully for the first few but the edges of the anvil/punch quickly rounded over so it soon became almost as much of a chore as using snips. I don't think it was a P&N, it looked pretty much the same but was bright yellow and the anvil was... more substantial.

To me the main fault was that in operation one needed a hand on the drill and a hand on the attachment, making things awkward when one needed a third hand for anything else. (Like, holding the sheet or stopping yourself from sliding off the roof. :rolleyes:)

If I was doing that job again, I'd look at a dedicated unit even if only to free up a hand.

It's a good price compared with the others on the market. It was the price that was forcing me to consider a drill attachment. But for this one, the online reviews support your experience too. Thanks for that Letaage.

Good point. Never thought of that.

I can't vouch for the longevity of the tool, I have only had it for about a year and used it for one job, but I was impressed with how fast it cut and it seems decently made for the price.

I had also considered the drill attachment style nibblers and using snips for the job but the dedicated nibbler saved a lot of time and grief.

I have the same one and have used multiple times for various projects over the last 5 years or so and is still going strong, for $159.00 was a no brainer for me, does what it is designed to do and was not prepared to spend money on an attachment that might not do the job as well,.

[ErrolFlynn]

Thanks for that. Good to know.

You may have completed the job by now but this shear is another alternative.

I have the first one and used it extensively. I used it for cutting a Trimdeck profile. I found it worked better with a corded drill than a cordless drill, but much depends on the physical shape of the drill. My memory is that I used it so much it wore out an old Bosch drill that I had had for many years.

Having said that, I always thought a powered tool would be ideal for cutting the ridge capping to suit corrugated iron roofing.......until I saw my son do the same thing with tin snips.....much faster! You need curved cutting snips. Left cutting if you are right-handed and right cutting if you are left-handed. He did it entirely by sight, but if you are like me, measure the depth of the corru and draw a line along the flashing and mark off the peaks. Cutting such a short distance is much easier than long straight lines. My son did that fairly easily too.....using two straight cutting tin snips about 10/15mm apart and both hands! He is a reasonably accomplished carpenter/builder and it would seem ambidextrous.

:rolleyes:

These are the type of aviation style snips. Not a recommendation one way or the other. Literally the first one that came up in a search. I was actually looking for the Weiss brand, but failed.

Thanks, Paul. It's useful to hear of practical experiences. I won't be starting my actual job for a while yet. I'm just gathering information.

Though, I have to say that as I will be cutting a lot of curves I suspect the nibbler will be best. I was planning/hoping to be able to design a jig with the profile I need. Presumably by running the nibbler against the template, the cut will be as near as perfect as I'm going to get. I doubt straight-edge snips or curved snips would manage that as well as the nibbler.
