Rotary metal shear drill attachment - useful?

[Stephen Tashiro]

Is the rotary type of metal shear drill attachment useful? - for example https://www.amazon.com/gp/slredirect/picassoRedirect.html/ref=pa_sp_atf_aps_sr_pg1_1?ie=UTF8&adId=A03200262ABSOEZZ8VTI1&qualifier=1680799253&id=658345145189290&widgetName=sp_atf&url=%2FElectric-Nibbler-Attachment-Adapter-Aluminum%2Fdp%2FB0BLSG7MJ6%2Fref%3Dsr_1_1_sspa%3Fc rid%3D3VAGRS9BJGHS4%26keywords%3Delectric%2Bdrill% 2Bshear%2Bnibbler%26qid%3D1680799253%26sprefix%3De lectric%2Bdrill%2Bshear%2Bnibbler%252Caps%252C1446 %26sr%3D8-1-spons%26psc%3D1%26smid%3DA3BCPFFGY5KRQW

I've not used that style but have used one that looked liked the working end of tin snips in a drill. It worked well for barn meral.

I would suggest discussing exactly what you need to cut first. I have a bunch of things to cut metal of all thicknesses but would have no use for that.

Harbor Freight sells a "knock off" version of a KEETS shear for $59.99. I've had a Millwalkie version for over forty years now. Cut a bunch of sheet metal with it.

I have an older one where a center finger goes up and down between two sides. So it cuts a small strip out completely. This prevents bending or distortion due to shear action.

Have used it for all kinds of things, including asphalt shingles. Tin, plastic sheet, anything under about 1/8" thick.

I think you meant to type Kett. I have a set (I believe they are still made in the US) and they work great.

I think I would buy the HF Bauer version over that attachment on Amazon. If it doesn't do what you want then you can return it. The Bauer will cut thicker gauge sheet metal.

Yes, this is the drill adapter version I have and feel it is useful. Didnt know what it was called, thanks.

I have used several special purpose electric metal shearing tools with the same type of action. They didn't work well on metal roofing. They couldn't cut across the ribs on the roofing without a lot of manipulation. I've never used a drill attachment with that type of action - even though I have two of them that I've never unpacked!

I don't have any immediate need to cut sheet metal. I'm just curious whether the rotary (as opposed to the scissors) type tool works well.

[Tom M King]

I would wait until you have a need, and then buy the right tool for the job. Chances approach 100% that if you buy it just in case that when a job comes up it won’t be what you need.

[Tom M King]

If you want something just in case, get a red and green pair of offset Milwaukee tin snips. Odds are you would need them even if those shears ever were needed. Offset keeps your hand up above the sheet metal on long cuts.

Wiss require some fiddling with eccentric bolts. Milwaukee’s are ready to go and stay ready.

[Tom M King]

You can make straight cuts with either, but for curves and access in tight spots, one cuts curves to the left and the other to the right.

The 809 ratings look really good! BUT if you use the "fakespot" browser add-in to analyze the reviews they give the authenticity of the posted reviews a grade of "D". So I would guess a bunch of shill reviews.

Wiss snips have worked well for me. Don't think I'll ever need to replace them but it's good to know that Milwaukee makes good ones too. Once had Craftsman but they were umm...unsatisfactory.

For anyone who has not used lefts and rights their value is a mystery. They take metal cutting up a level.

This just popped up when I was looking at another video. I want one now.

lost the video. looking.
